The quantity of committed dose depends on the amount of ingested radioactive material and the time it stays inside the body. The total dose accumulated during the 50 years following the intake is called the committed dose. When a radioactive material gets in the body by inhalation or ingestion, the radiation dose constantly accumulates in an organ or a tissue. Commonly used subunits are mCi (millicurie), ♜i (microcurie), nCi (nanocurie), and pCi (picocurie).ġ Ci = 1000 mCi 1 mCi = 1000 ♜i 1 ♜i = 1000 nCi 1 nCi = 1000 pCi.īecquerel (Bq) or Curie (Ci) is a measure of the rate (not energy) of radiation emission from a source. One curie is a large amount of radioactivity. Commonly used multiples of the Bq unit are kBq (kilobecquerel), MBq (megabecquerel), and GBq (gigabecquerel).ġ kBq = 1000 Bq, 1 MBq = 1000 kBq, 1 GBq = 1000 MBq.Īn old and still popular unit of measuring radioactivity is the curie (Ci). One becquerel is an extremely small amount of radioactivity. Radioactivity or the strength of radioactive source is measured in units of becquerel (Bq).ġ Bq = 1 event of radiation emission per second. It does not take into account food you eat which contains radition.
Parameters shown are reasonable initial values which can be modified as needed. The calculator only determines dose rates for situations, where the activity concentration or annual exposure of radon and/or its progeny is known. The calculator only determines doses to exposed individuals. This calculator performs radiation dose calculations for individuals exposed to Radon-222 and its decay products. (working level month)1 WL exposure for 170 hours
