Human bodies, in the natural radioactive background of earth, are radioactive. There
are presence of the radionuclides, 40K, 14C and 3H, as the isotopic components of
the respective naturally occurring body-constituent elements. The average effective
internal radiation dose for a 70 kg reference man has been estimated to be about
0.3 mSv/y which in comparison with the accepted International Standard of radiation
exposure dose of 3 mSv/y for a man, may not be so harmful.

Abstract


Human bodies, in the natural radioactive background of earth, are radioactive. There
are presence of the radionuclides, 40K, 14C and 3H, as the isotopic components of
the respective naturally occurring body-constituent elements. The average effective
internal radiation dose for a 70 kg reference man has been estimated to be about
0.3 mSv/y which in comparison with the accepted International Standard of radiation
exposure dose of 3 mSv/y for a man, may not be so harmful.
