time
Exposure from radioactive materials taken into the body by breathing or swallowing radioactive dusts, vapors or gases. It is also possible to absorb through the skin through cuts or abrasions. Any radioactive material which presents an external hazard is likely to be an even more serious hazard if it gets into the body. Protection - Shielding by special protective clothing, breathing apparatus, no smoking or eating in the area, prompt, thorough washing of personnel, clothing and tools immediately after exposure.
