What is radiation hazardous?
Ionizing radiation. Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.
Is red a safety color?

Who made the radiation symbol?
The life of the radioactive ‘trefoil’ began in 1946 at the University of California, Berkeley. The symbol was first ‘doodled’ by members of a research group headed by Nels Garden, who wrote in a letter that the symbol “would best symbolize the degree of hazard, type of activity, etc., but which was simple in design”.
How many hazard symbols are there?
The GHS system, part of OSHA’s Hazard Communication Standard (HCS), consists of nine symbols, or pictograms, providing recognition of the hazards associated with certain substances. Use of eight of the nine are mandatory in the U.S., the exception being the environmental pictogram (see below).
How many types of radiation hazards are there?
There are four basic types of ionizing radiation: Alpha, beta, gamma and x-ray, and neutron particles. All of these types of radiation are caused by the activity of unstable atoms. Alpha radiation comes from the decay of heavy atoms such as uranium and radon.
Is radiation a physical hazard?
Physical hazards include exposure to slips, trips, falls, electricity, noise, vibration, radiation, heat, cold and fire. The following table summarizes the sources of physical hazard exposure and their health effects.
What are the types of hazards?

What is the blue glow from radiation?
Caused by particles traveling faster than light through a medium, Cherenkov Radiation is what gives nuclear reactors their eerie blue glow. As it turns out, that spooky blue light is a real phenomenon, and it’s called Cherenkov Radiation.
