Health risk of radioactive material How does radioactive material case health effect ? strip away electrons from atoms break some chemical bonds How does radioactive material case health effect ? strip away electrons from atoms break some chemical bonds

What kinds of health effects does exposure to radiation cause? stochastic non-stochastic 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. Is any amount of radiation safe? There is no firm basis for setting a "safe" level of exposure above background for stochastic effects.
