Becquerel bq - Study guides, Class notes & Summaries

The radiation dose or amount of radiation that has been absorbed by a substance. Measured in rads (grays). - Answer absorbed dose The process whereby the particles or photons in a beam of radiation are reduced in number or energy as they pass through a medium. - Answer absorption The process of bombarding stable atoms with neutrons to make them radioactive. - Answer activation The activity of a radioisotope is the number of disintegrations that occur for a given quantity of the radiois...
