Evaluation of thoron-daughter instruments

Creators

Description

Several DOE decontamination and decommissioning sites need to accurately measure thoron-daughter concentrations during decontamination efforts. Because the workers at these sites receive their dose from thoron-daughters rather than thoron gas, the thoron-daughter concentration is the measurement of interest. Some instruments currently used for making radon-daughter concentration measurements also claim the ability to measure thoron-daughter concentrations. This study evaluated the validity of those claims
