Define as the type of waste consist of radionuclides exceed the level a adopted by IAEA

Radioactive waste

Philosophy of radioactive waste managementProtection of people and environment from the harmful effects of ionizing radiation

Basic concept radiation protection TimeShieldingDistant

Oil drilling : NORM waste {238U ,226Rn 222Rn}Mining : {238U ,226Rn 222Rn}Medical : {60Co ,137Cs and 125,131I}Industry : {90Sr ,192Ir and Am Be }Reactor {Spent fuel and Fuel processing}Military :depleted uranium

What kinds of health effects does exposure to radiation cause?stochastic non-stochastic

Is any amount of radiation safe?

There is no firm basis for setting a "safe" level of exposure above background for stochastic effects.

How do we know radiation causes cancer????????????????????(depend on human immune system)

Aren't children more sensitive to radiation than adults?Yes, becausechildren are growing more rapidly there are more cells dividing
