radioactive contamination. Flashcards
what is radioactive contamination?
unwanted presence of materials containing radioactive atoms on other materials.
what is the hazard of the contamination caused by?
due to the decay of the contaminating atoms.
what is the type of radiation emitted which effects the hazard?
irradiation.
what is irradiation?
process of exposing an object to the hazard.
deliberate or accidental.
doesn’t cause the object to become radioactive.
when using radioactive sources you can protect yourself against unwanted radiation by doing what?
using sources at the lowest activity possible for the shortest amount of time as possible.
wearing appropriate clothing such as a lead apron.
not handling sources with bare hands.
what are some examples of where you need to be able to compare hazards associated with contamination and irradiation?
food contaminated with an alpha source would be more hazardous than food contaminated with a gamma source.
an area contaminated with an alpha source would not be dangerous unless it was entered.
