Abstract

The exposure rate constant r is calculated and tabulated for 1084 nuclides. The exposure rate constant is defined as the ratio of the product of the exposure rate and the square of the distance from a radioactive point source to the source
strength Q.

The dose equivalent rate constant T is here defined as the ratio of the mean dose equivalent rate to a water cylinder of 30 cm diameter and 100 cm height placed 100 cm from a radioactive source to the source strength Q. The source is placed at the midplane of the cylinder. The dimensions of the cylinder were chosen to approximate a human phantom of 70 kg mass. The dose equivalent rate constant is calculated and tabulated for 1084 nuclides. For both quantities, r and T, the contributions from photon energies below 30 keV and X-rays are omitted.

The data are based on the Evaluated Nuclear Structure Data File, which is compiled by the Nuclear Data Group at Oak Ridge National Laboratory.
