Estimation of shallow-dose equivalent using a two-element dosimeter.

Abstract

Estimation of shallow-dose equivalent using a two-element dosimeter is described under the guidelines of a standard adopted by the Health Physics Society Standards Committee and the dosimetry practices followed by most dosimeter processors. This standard is to be used in a future mandatory testing program in the U.S. A mathematical formulation, correlating dosimeter response and "shallow-dose equivalent factors" at different energies, is presented. A thermoluminescent dosimeter (TLD), currently used at the Idaho National Engineering Laboratory, is examined for determining shallow-dose equivalent response and the results are discussed for beta as well as photon responses.
