As a radiation safety expert, I've spent a considerable amount of time studying the relationship between radiation and its perception in various media and culture. The association of green with radiation is a fascinating subject that has roots in both scientific phenomena and cultural representations.
The perception of green as a color associated with radiation likely stems from the phenomenon known as Cherenkov radiation. Cherenkov radiation occurs when charged particles, such as electrons, travel through a medium like water or air at a speed faster than the speed of light in that medium. This causes the particles to emit a faint glow, which can appear blue or green depending on the medium and the observer's perspective. This effect is named after the physicist Pavel Cherenkov who first described it. The blue or green glow is not inherent to radioactivity itself but is a byproduct of the interaction between fast-moving particles and the medium they are traveling through.
In the context of nuclear reactors and other facilities where radioactive materials are handled, workers often wear special badges designed to detect exposure to radiation. These badges contain materials that react to ionizing radiation, and while they do not emit a green glow, they serve as a reminder of the invisible nature of radiation. The badges are a crucial tool for monitoring the safety of workers and ensuring that they are not exposed to harmful levels of radiation.
The cultural association of green with radiation has been further reinforced by its use in various forms of media, including movies, television shows, and video games. Often, radiation is depicted with a green glow to make it visually identifiable to the audience. This visual representation has become a convention, and while it is not scientifically accurate, it has become a part of the collective understanding of what radiation "looks" like.
It is important to note that the actual color of radiation, if it could be seen by the human eye, would not be green. Radioactive materials do not emit visible light on their own. The glow associated with radioactivity in media is purely a creative choice to make an invisible force visible and to evoke a sense of danger or mystery.
In conclusion, the association of green with radiation is not based on scientific fact but rather on a combination of a specific physical phenomenon, the need for visual representation in media, and the cultural understanding that has developed over time. While Cherenkov radiation can produce a blue or green glow under certain conditions, this is not a characteristic of radioactivity itself. The use of green to represent radiation in media has become a convention that has influenced public perception, even though it does not accurately reflect the physical properties of radiation.

They have to wear special radiation exposure detection badges, precisely because radioactivity is invisible. ... When the electrons fell back down to their original energy level, they gave off a greenish glow -- hence the myth of anything radioactive having a green glow.May 20, 2008
