Radiation travels with a speed either equal to, or almost equal, to the speed of
The ability of radiation to penetrate the human body ranges from very little (less
than 1/1000th for alpha particles) to deep penetration (gamma rays).
This radiation travels in straight lines with some scattering.
Some types of ionizing radiation are very well absorbed by air--(examples--alpha,
beta, and neutrons); other types are not absorbed by air (example--gamma
rays). (para 2-4)
Skin or bones.
The gestation stage at which the radiation occurs. (para 2-5c)

Survey leakage or exposure to radioactive sources.
Enforcement of SOPs on radiation.
