Dose per content function

A set of tabulated values $z(t) = e(50)/m(t)$ or $z(t) = h_T(50)/m(t)$ used in assessing exposures from occupational intakes of radionuclides, where $e(50)$ is the effective dose coefficient, $h_T(50)$ is the equivalent dose coefficient for a tissue or organ, and $m(t)$ is the reference bioassay (retention or excretion) function. Values of $z(t)$ represent the committed effective dose or committed equivalent dose to an organ $r_T$ per predicted activity content in the body or in a given organ (Sv Bq^-1) or per daily excretion.
