A tattoo depicting radiation means a warning against danger, a threat, the death of nature and all living things, the study of the forbidden and the unknown, an attraction to the unknown, a tendency to make spontaneous decisions, a craving to look for something new, a love of collecting, a fan of a work or a computer game "Stalker" .
The value of the radiation tattoo
The symbol of radiation (radiation hazard) is one of the twelve signs developed and adopted by the world community, which indicate a certain area with some kind of threat to human life and health.
Outwardly, the sign of radiation is well known and looks like a yellow circle, which is divided into six parts, resembling petals or propeller blades, three of which are black. In this case, two such black sectors look up, and one down.
According to the first version, the indicated sign of radiation represents an inverted shamrock, which embodies the death of all living things. According to the second interpretation, this black and yellow sign resembles the military banner of the inhabitants of Japan, who live on its western islands. A third version has also been established that this graphic symbol of radiation hazard represents an atom with three types of its radiation - Alpha, Beta and Gamma.
Despite the seemingly positive yellow color against the background of the sign, this circle does not cause any positive emotions in a person, including if applied to the body as a tattoo. Even nature has created such a combination of colors as a clear signal of danger, as evidenced by such a bright color of poisonous insects and snakes, which, by their appearance, seem to warn to stay away from them.
The meaning of a tattoo depicting radiation appears completely different if its owner is familiar and is a true connoisseur of such an exciting computer game as Stalker. The intention of the creators is that the main character in the story becomes a resident of a new era - the world that survived after the Chernobyl disaster, in which global transformations took place. The player becomes a stalker, that is, a person whose occupation is the study and development of previously forbidden unexplored territories, who must find certain objects and anomalies located in the exclusion zone, that is, in radioactive terrain.
If the owner of the tattoo puts a sign of radiation hazard as a symbol of "Stalker", then the image will have the following meanings.
The first is an irresistible craving for the unknown, the unknown. This interpretation is close to a person who can often make rash decisions and strive to constantly look for something new. The owner of such a tattoo cannot sit in one place idle, he is always in a state of search for the best.
The second is the passion for collecting. Often, fans of games or works with a plot similar to Stalker are seriously passionate about collecting strange, extraordinary things in their opinion.
The third and most banal is a sign of love for a game or a book. Basically, fans of "Stalker" on the verge of fanaticism put this meaning into the tattoo, but these are rare.

Story
At that time, there were a huge number of different warning symbols, but there was no standardization. So Dow decided to develop its biohazard symbol. More than one department of the company was involved in its development. The requirements were simple - you need a unique, simple, but memorable sign. To this end, a public study was conducted, as a result of which the most memorable symbol was chosen. It turned out to be this three-sided symbol of a bright orange color, since it is this color, as various studies have shown, that is best seen under any conditions.
Charles Baldwin, an environmental engineer who was involved in the design of the sign, said:
After that, the symbol was presented to the scientific community, and was approved by all necessary authorities. Today, this “biohazard” sign can be found in laboratories around the world.
Appearance
All parts of the biohazard label may be drawn using a compass and/or straightedge. The main outline of the symbol is a simple trefoil, which is made up of three equally intersecting circles, as in a triple Venn diagram, where the intersecting parts are erased. The diameter of the intersecting part is equal to half the radius of these three circles. Then, three inner circles are inscribed in the original circles with a size of 2/3 of the radius of the original circles so that they slightly touch the outer side of the three intersecting circles. The small circle in the center has a diameter equal to half the radius of the three inner circles, its arcs are erased at 90, 210, 330 degrees. The arcs of the inner circles and the small circle are connected by lines. And finally, the ring below it is at a distance of the perimeter of an equilateral triangle formed by the centers of three intersecting circles. The outer circle of the ring is drawn and closed with arcs from the centers of the inner circles with a shorter radius of the inner circles
warning sign
Warning signs typically use an exclamation point to warn, draw attention to danger or surprises.
chemical hazard
A chemical hazard symbol is a pictogram used on containers of hazardous chemicals to indicate specific risks and necessary precautions. The various notation systems are shown below.
The National Fire Protection Association in the United States has a diamond-shaped symbol with four colored sections and numbers in them indicating the degree of threat (from 0 to 4; 0 - no risk, 4 - maximum risk). The red section indicates flammability, the blue section indicates health risks, the yellow section indicates explosiveness, and the white section indicates special information. This designation is used primarily in the United States.
Europe uses a different standard. Rolling stock carrying dangerous goods is marked with an orange sign, on which the bottom number indicates the substance being transported, the top number indicates the danger that it may pose.

Hazard symbols in the Russian Federation
In the Russian Federation, there is GOST R 12.4.026-2001 “Signal colors, safety signs and signal markings”, which establishes the purpose, application rules, types and designs, color image, dimensions, technical requirements and characteristics, test methods for safety signs, including and containing danger symbols. In accordance with this GOST, safety signs are a color-graphic image of a certain geometric shape using signal and contrasting colors, graphic symbols and (or) explanatory inscriptions, designed to warn people about an immediate or possible danger, to prohibit, prescribe or permit certain actions, as well as to information about the location of objects and means, the use of which eliminates or reduces the impact of dangerous and (or) harmful factors. Safety signs are standardized and are also given in the previous GOST R 12.4.026 SSBT “Signal colors, safety signs and signal markings”
Types of safety signs
1. Forbidding - a red circle with a white field inside, crossed out by an inclined red stripe;
2. Warning - an equilateral yellow triangle with rounded corners, apex up, with a black border;
3. Prescriptive - a green square with a white border and a white square-shaped field;
4. Index - a blue rectangle, edged with a white border along the contour with a white square inside.
Symbolic images made in black color are placed inside the sign, specifying the content of the sign. If necessary, additional plates with explanatory inscriptions are used to clarify or strengthen the effect of the sign.
The zone of validity of signs placed at the entrance (entrance) to the production facility applies to the entire facility.

An excerpt characterizing the symbols of danger
“Yes, I was,” Pierre answered. “Tomorrow there will be another battle ...” he began, but Natasha interrupted him:“But what about you, Count?” You don't look like yourself...
“Ah, don’t ask, don’t ask me, I don’t know anything myself. Tomorrow... No! Farewell, farewell,” he said, “terrible time!” - And, lagging behind the carriage, he moved to the sidewalk.
Natasha still leaned out of the window for a long time, beaming at him with an affectionate and slightly mocking, joyful smile.
Pierre, since his disappearance from home, had been living for the second day in the empty apartment of the late Bazdeev. Here's how it happened.
Waking up the next day after his return to Moscow and meeting with Count Rostopchin, Pierre for a long time could not understand where he was and what they wanted from him. When, among the names of other persons who were waiting for him in the waiting room, he was informed that a Frenchman was also waiting for him, who had brought a letter from Countess Elena Vasilyevna, he was suddenly overcome by that feeling of confusion and hopelessness, which he was able to succumb to. It suddenly seemed to him that everything was now over, everything was mixed up, everything had collapsed, that there was neither right nor wrong, that there would be nothing ahead and that there was no way out of this situation. He, smiling unnaturally and muttering something, then sat down on the sofa in a helpless pose, then got up, went to the door and looked through the crack into the waiting room, then, waving his hands, I returned back and took up the book. Another time, the butler came to report to Pierre that the Frenchman, who had brought a letter from the countess, really wanted to see him even for a minute, and that they had come from the widow of I. A. Bazdeev to ask to accept the books, since Ms. Bazdeeva herself had left for the village.
“Ah, yes, now, wait ... Or not ... no, go tell me that I’ll come right now,” Pierre said to the butler.
But as soon as the butler came out, Pierre took the hat that lay on the table and went out of the office through the back door. There was no one in the corridor. Pierre walked the entire length of the corridor to the stairs and, grimacing and rubbing his forehead with both hands, went down to the first platform. The porter stood at the front door. From the platform to which Pierre descended, another staircase led to the back door. Pierre followed it and went out into the yard. Nobody saw him. But on the street, as soon as he came out of the gate, the coachmen standing with the carriages and the janitor saw the master and took off their hats in front of him. Feeling the fixed gazes on himself, Pierre acted like an ostrich that hides its head in a bush so that it will not be seen; he lowered his head and, quickening his pace, walked down the street.
Of all the things that lay ahead of Pierre that morning, the business of dismantling the books and papers of Iosif Alekseevich seemed to him the most necessary.
He took the first cab he came across and ordered him to go to the Patriarch's Ponds, where the house of Bazdeev's widow was.
Constantly looking from all sides at the moving carts of those leaving Moscow and recovering with his fat body so as not to slip off the rattling old droshky, Pierre, experiencing a joyful feeling similar to that experienced by a boy who has run away from school, started talking with the cab driver.
The driver told him that today they were dismantling weapons in the Kremlin, and that tomorrow the whole people would be driven out beyond the Trekhgornaya outpost, and that there would be a big battle.
Arriving at the Patriarch's Ponds, Pierre found Bazdeev's house, which he had not been to for a long time. He approached the gate. Gerasim, the same yellow, beardless old man whom Pierre had seen five years ago in Torzhok with Iosif Alekseevich, came out to his knock.
- Houses? Pierre asked.
- Due to the current circumstances, Sofya Danilovna and the children left for the Torzhkov village, Your Excellency.
“I’ll go in anyway, I need to sort out the books,” said Pierre.
- Please, you are welcome, brother of the deceased, - the kingdom of heaven! “Makar Alekseevich remained, yes, as you please know, they are in weakness,” said the old servant.
Makar Alekseevich was, as Pierre knew, the half-mad brother of Iosif Alekseevich who drank heavily.
– Yes, yes, I know. Let's go, let's go ... - said Pierre and entered the house. A tall, bald old man in a dressing gown, with a red nose, in galoshes on his bare feet, was standing in the hall; seeing Pierre, he angrily muttered something and went into the corridor.
“They were of great intelligence, but now, as you will see, they have weakened,” said Gerasim. - Do you want to go to the office? Pierre nodded his head. - The office was sealed as it was. Sofya Danilovna was ordered, if they come from you, then release the books.
Pierre entered the very gloomy office into which he had entered with such trepidation during the life of the benefactor. This office, now dusty and untouched since the death of Iosif Alekseevich, was even gloomier.
Gerasim opened one shutter and tiptoed out of the room. Pierre walked around the office, went to the cabinet in which the manuscripts lay, and took out one of the once most important shrines of the order. These were genuine Scottish acts, with notes and explanations from the benefactor. He sat down at the dusty writing table and laid the manuscripts in front of him, opened them, closed them, and finally, pushing them away from him, leaning his head on his hands, he thought.
Several times Gerasim carefully looked into the office and saw that Pierre was sitting in the same position. More than two hours have passed. Gerasim allowed himself to make some noise at the door in order to draw Pierre's attention to himself. Pierre did not hear him.
- Will you order the driver to let go?
“Ah, yes,” Pierre said, waking up, hastily getting up. “Listen,” he said, taking Gerasim by the button of his coat and looking down at the old man with his shining, moist, enthusiastic eyes. “Listen, do you know that tomorrow there will be a battle? ..
“They did,” answered Gerasim.
“I ask you not to tell anyone who I am. And do what I say...
- I obey, - said Gerasim. - Would you like to eat?
No, but I need something else. I need a peasant dress and a pistol,” said Pierre, suddenly blushing.
“I’m listening,” said Gerasim after thinking.
Pierre spent the rest of that day alone in the benefactor's study, pacing uneasily from one corner to another, as Gerasim heard, and talking to himself, and spent the night on the bed prepared for him right there.
Gerasim, with the habit of a servant who had seen many strange things in his lifetime, accepted Pierre's relocation without surprise and seemed to be pleased that he had someone to serve. On the same evening, without even asking himself what it was for, he got Pierre a caftan and a hat and promised to get the required pistol the next day. Makar Alekseevich that evening twice, slapping his galoshes, went up to the door and stopped, looking ingratiatingly at Pierre. But as soon as Pierre turned to him, he bashfully and angrily wrapped up his dressing gown and hurriedly left. While Pierre, in a coachman's caftan, purchased and steamed for him by Gerasim, went with him to buy a pistol at the Sukharev Tower, he met the Rostovs.
On September 1, at night, Kutuzov ordered the retreat of Russian troops through Moscow to the Ryazan road.
The first troops moved into the night. The troops marching at night were in no hurry and moved slowly and sedately; but at dawn, the advancing troops, approaching the Dorogomilovsky bridge, saw in front of them, on the other side, crowding, hurrying along the bridge and on the other side rising and flooding the streets and alleys, and behind them - pushing, endless masses of troops. And causeless haste and anxiety seized the troops. Everything rushed forward to the bridge, onto the bridge, into the fords and into the boats. Kutuzov ordered that he be taken around the back streets to the other side of Moscow.
By ten o'clock in the morning on September 2, only the troops of the rear guard remained in the Dorogomilovsky suburb. The army was already on the other side of Moscow and beyond Moscow.
At the same time, at ten o'clock in the morning on September 2, Napoleon stood between his troops on Poklonnaya Hill and looked at the spectacle that opened before him. From August 26 to September 2, from the battle of Borodino to the entry of the enemy into Moscow, all the days of this anxious, this memorable week, there was that extraordinary autumn weather, which always surprises people, when the low sun heats hotter than in spring, when everything glitters in the rare, clean air so that it hurts the eyes when the chest grows stronger and fresher, inhaling the odorous autumn air, when the nights are even warm and when in these dark warm nights from the sky incessantly, frightening and delighting, golden stars are pouring.
On September 2, at ten o'clock in the morning, the weather was like this. The sparkle of the morning was magical. Moscow from Poklonnaya Gora spread out spaciously with its river, its gardens and churches, and it seemed to live its own life, quivering like stars, its domes in the rays of the sun.
At the sight of a strange city with unprecedented forms of extraordinary architecture, Napoleon experienced that somewhat envious and restless curiosity that people experience when they see the forms of an alien life that does not know about them. Obviously, this city lived with all the forces of its life. By those indefinable signs by which, at a long distance, a living body is unmistakably recognized from a dead one. Napoleon from Poklonnaya Gora saw the trembling of life in the city and felt, as it were, the breath of this large and beautiful body.
- Cette ville asiatique aux innombrables eglises, Moscou la sainte. La voila donc enfin, cette fameuse ville! Il etait temps, [This Asiatic city with countless churches, Moscow, their holy Moscow! Here it is, finally, this famous city! It's time!] - Napoleon said and, getting off his horse, ordered the plan of this Moscou to be laid out in front of him and called the translator Lelorgne d "Ideville. "Une ville occupee par l" ennemi ressemble a une fille qui a perdu son honneur, [City occupied by the enemy , is like a girl who has lost her innocence.] - he thought (as he said this to Tuchkov in Smolensk). And from this point of view, he looked at the oriental beauty lying in front of him, which he had never seen before. It was strange to him that, at last, his long-standing, which seemed to him impossible, wish had come true. In the clear morning light, he looked first at the city, then at the plan, checking the details of this city, and the certainty of possession thrilled and terrified him.
“But how could it be otherwise? he thought. - Here it is, this capital, at my feet, waiting for its fate. Where is Alexander now and what does he think? Strange, beautiful, majestic city! And strange and majestic this minute! In what light do I present myself to them! he thought of his troops. “Here it is, the reward for all these unbelievers,” he thought, looking around at those close to him and at the troops approaching and lining up. - One word of mine, one movement of my hand, and this ancient capital of des Czars perished. Mais ma clemence est toujours prompte a descendre sur les vaincus. [kings. But my mercy is always ready to descend to the vanquished.] I must be magnanimous and truly great. But no, it's not true that I'm in Moscow, it suddenly occurred to him. “However, here she lies at my feet, playing and trembling with golden domes and crosses in the rays of the sun. But I will spare her. On the ancient monuments of barbarism and despotism, I will write great words of justice and mercy ... Alexander will understand this most painfully, I know him. (It seemed to Napoleon that the main significance of what was happening lay in his personal struggle with Alexander.) From the heights of the Kremlin - yes, this is the Kremlin, yes - I will give them the laws of justice, I will show them the meaning of true civilization, I will force generations boyars lovingly commemorate the name of their conqueror. I will tell the deputation that I did not and do not want war; that I waged war only against the false policy of their court, that I love and respect Alexander, and that I will accept peace conditions in Moscow worthy of me and my peoples. I do not want to take advantage of the happiness of war to humiliate the respected sovereign. Boyars - I will tell them: I do not want war, but I want peace and prosperity for all my subjects. However, I know that their presence will inspire me, and I will tell them, as I always say: clear, solemn and great. But is it really true that I'm in Moscow? Yes, here she is!
Biohazard sign
In the modern world, more and more often you can find interesting signs in a triangle. And one of these signs is called a biohazard sign. This sign is displayed in a triangle or square on a dark orange or yellow background.
Description of the biohazard symbol
The very basis of the symbol is an ordinary shamrock, which is based on three equal intersecting circles (highlighted in black in the figure). Inside these circles, three more are inscribed to the circle, the radius of which is 2/3 of the radii of the original circles. It can be seen that these three circles are inscribed closer to the outer side of the previous circles. The small circle in the center has a diameter equal to half the radius of the three inner circles and is connected by lines to the arcs of these circles. If you attach a protractor, you can see that these lines are located at angles of 90, 210 and 330 degrees. Under this whole figure in the center is a ring formed by the centers of the first three intersecting circles.
History of the Biohazard Sign
The biohazard label was developed in 1966 by the Dow Chemical Company. But at first, this mark was intended to be placed on the chemical products of this particular company. The requirements for developing the company's own logo were simple - it must be unique and memorable. And as a result of public research, this symbol turned out to be the most memorable of all presented on display.
Today, the biohazard sign can be found in all biological laboratories. And during its manufacture, as well as other danger signs, requirements are imposed in accordance with GOST R 12.4.026-2001.
It is not difficult to guess what the biohazard sign, or the so-called "biohazard", is intended for. It denotes a threat associated with the harmful effects on a living organism of various kinds of pathogens.
Some facts from history
In the 60s of the last century, scientist Charles L. Baldwin expressed his opinion that it was necessary to come up with a special symbol that would let others know about the danger of the object to which it is attached.
First of all, the use of this kind of sign should have spread to such areas of life as healthcare, industry and science.
To bring his idea to life, Baldwin began to collaborate with a design team that also worked in his company and until now was engaged in a rather unremarkable business - packaging design.
After some time, the biohazard sign created by joint efforts began to appear only in some laboratories, hospitals, storage facilities, and then all over the world.
What do we need to draw?
Thanks to the uncomplicated design, drawing a biohazard sign is quite simple. We will need: a simple pencil, a sheet of paper, a pen (ideally black gel), a compass, an eraser and a bit of patience, which is always necessary for a good artist.
Getting Started
To explain everything to readers intelligibly and clearly, we suggest drawing a biohazard sign in stages.
First of all, using a compass, draw a circle. Its diameter should not be too large relative to the paper sheet.
At the second stage, we add small “tubes” to the central (very first) circle, as shown in the figure below. This must be done so that the arcs between adjacent "tubes" are equal to each other.
Now you need to draw three identical circles. This is done as follows: at the same distance from the central circle (it must be greater than the third, largest circle), three points are deposited, which should lie, as it were, on the continuation of the “tubes”. We put the compass on one of the existing points and draw a circle so that it touches the nearest ends of the "tube".
As you can see, between the second and third circles just drawn, a figure resembling a bent rectangle has formed. We simply paint over this space.
Now, using the outside of the three circles as a guide, draw three curved U-shapes (as shown in the photo). Albeit remotely, but the drawing already resembles a biohazard sign.
We paint over the resulting figure, leaving the “tubes” white. We wait until the ink or paint dries, and erase the unnecessary components that were drawn with a simple pencil with an eraser.
The international biohazard sign is ready. How you will use it is only a figment of your imagination.
We hope that the article on how to draw a biohazard sign in stages was useful to you.
Walking zabroshkam, do not forget to follow basic safety rules. This should help us. In particular, I would like to review the most common warning signs.
These pointers refer to danger symbols- easily recognizable symbols designed to warn of hazardous materials or locations.
