sign of radiation - it is one of the 12 accepted everywhere signs showing areas with a particular view of the threat to human life and health.The statement "Caution Radiation!" Became topical immediately after the Second World War.It was invented and first used the sign of radiation hazards in the laboratory of the American University of California at Berkeley.Physicists from Berkeley played a significant role in the invention of the atomic bomb, and then hydrogen.The process of the invention, the sign after, in 1952, was described in a letter to one of the participants - chemist Nelsen Gardena.A small group of researchers offers some sign of samples, and have chosen this that best visualized the threat.He was purple on a blue background.Purple in his Roman value was chosen because of the high cost of this particular color of paint - is excluded mindless copying, writes Garden.Furthermore, it does not conflict with any other popular in this field of science color.The same principle has been chosen and a blue background color.
black on yellow
modern image - a black mark on a yellow background - it came later, when the signs of radiation have been used more frequently.Objects carrying radioactive danger was over.Gardena, one of the inventors of the mark, did not like the black on a yellow sign of radiation.He believes that the frequent use of the yellow color in the designation of objects disavows any danger of increased risk is radiation.In addition, the yellow sign is difficult to see against the bright blue sky.Nevertheless yellow background was selected in 1948 in the standardization of the sign as the primary.The sign of three petals and three blades is remained purple.The authors found a new image that is a combination of colors is clearly seen in the open air at a distance of 20 feet.Today's American standards (ANSI), established in the late 1950s, and allow the use of black and purple marks radiation.
visual sign value
Interestingly, usually in the form labels are classic triangle with a particular image inside.According to the Russian guests, this sign - a warning.Signs of poison and radiation are represented in 9 of the 10 cases on the basis of the square.By itself, a sign of radiation - circle, which is divided into six sectors.Three of them - black.Two black petal-sector show up, one down.What does he sign?There are two versions.The first - an inverted shamrock as a symbol of nature destruction, a second, more cynical - a sign similar to the battle flag of the Japanese living in the west of the island empire.By the way, surprising similarity of the sign with radiation symbol automaker Mitsubishi.But the upside.
new sign of radiation
In 2007, a new sign or ionizing radiation hazard.This interest is a sign of radiation in the pictures.On the red background is shown in black traditional sign of radiation, skull and crossbones - the sign of death, running man - a call to leave the affected area.The authors believe that this sign is more understandable.But for some reason, difficult to explain, as a source of danger - the same is not clear layman trilobes fan, not all at once and not perceived as a mortal threat!IAEA sincerely believes that a new sign will be clear less educated people who do not understand the first character, which has no intuitive echo in the soul of a representative of poorly educated people.Somehow, their confidence makes you wonder.Which intuitive echo of this propeller should cause a Czech or Swedish?However, the IAEA is now trying to introduce a new sign it, despite its more complex visual perception.Interestingly, on the recognition of new signs of radiation were tested in countries such as the United States, Morocco, Kenya, Thailand, India and Ukraine.Symbol agreed with the World Organization for Standardization ISO, and in industry implemented by means of its implementation mechanisms.
And where does Roerich?
But is there any other kind of intuitive symbols have this sign?Surprisingly its similarity with the flag Roerich.Three circles in a circle, similarly arranged petals sign of radiation.There is a certain esoteric version, which says that the earth rests on some cosmic way, but the road was closed distortions in the application of nuclear weapons.So sign radioactive danger - it upended the way and sign the Roerich Banner.An analogue of an inverted pentagram or the crucifixion.But even without the obvious symbolism Way opposition symbol of peace (pax culturae) and the nuclear threat.
Application radiation hazard signs
Initially in America soon after the invention of his plan to put a mark on the refuge designed to protect against nuclear threats.Then this idea was abandoned, as the sign indicates danger, not hiding from it.Now, according to GOST 17925-72, in Russia this sign indicate the room objects and devices that carry the actual or potential radiation hazards.It may be nuclear, vehicles, in which there is a transport of radioactive substances, physical laboratories, accelerators and many other facilities, really carrying radioactive danger.In short, where the radiation level is really elevated.Allowed to use the sign of radioactive hazard for educational purposes, conferences, booklets, during training.According to the Standard, the use of radiation hazard sign for avatars on social networks and in the manufacture of jewelry, and other similar purposes is not allowed.But nobody is watching.And the sanctions for disorderly and unauthorized use of the mark is not provided.According to GOST, by the way, the shamrock has to be red, but allowed and black on a white background.
Coverage
signs of radiation can celebrate not only objects, but also space.The range of characters, standing at the entrance to the industrial facility, covers the entire territory of the object.There is the concept of "zone", has, thanks to the "Stalker" by the Strugatsky brothers, their emotional.Who is somewhere on the border between the civil defense and cyberpunk campaign is to find places from radiation contamination, preserved since the Soviet times, and activists try to mark them as characters, even if made in the form of graffiti on the walls.But activists are not always right.The danger may be imaginary.And people saw a "black propeller" on a yellow background on the wall of his house on the street, getting nervous.Most likely, the state program is needed to search for, identify and decontaminate such sites, along with the campaign of debunking rumors.And if such rumors, that is misinformation, someone is engaged professionally in India as global corporations struggled with nuclear power?The new radiation warning sign too similar to the visualization of the wrath of the gods, and call for the destruction of the object of their anger was kindled.In short, the use of radiation danger signs need eyes to eyes.
signs of radiation and the human psyche
It is obvious that the human psyche tend to exaggerate the threat.Radiation hazard scares a long time, it is clear that the population of the Far East, these fears did not arise out of nowhere.Radiation and people are familiar with, of course, since the beginning of mankind, the relic radiation of the radiation has always been, but now the fear of mutations and changes in the genetic code under the influence of the hidden sources of radiation as great as ever.And not just word of mouth, but also the media fanning the rumors intensified.Perhaps, very soon data on background radiation we will get together with the weather forecast, and at airports to passengers' luggage will be pasting posters - "radiation is safe."
Underground
Interestingly, for advanced youth these characters have become part of the club culture.Many nightlife mark this sign cocktails, private areas and even bathrooms.All is good, the mentality of the younger generation and not so kind.Young happy to modernize sign of radiation, a photo of him in the gas, oil, or a fashionable style can be seen in various design projects.But again, remember the old anecdote about a boy and the wolf attacked him ... If the sign is used many times in a safe situation, consciousness can ignore it in a situation of danger.
Hopefully, our hipsters and ravers will not seek atomic bomb shelter in the near future, or confuse them with a smoking room, but some state control over the use of the sign is not intended to be present.
