Abstract
Exact working-level hour cumulative exposure measurements require knowledge of all the potential a energy in 1 liter of air, with this a energy coming from the decay of raa and rac' daughters. This can be done by measuring a emission from the daughters with a system that also determines the energy of the a particle, and is, therefore, able to determine which daughter decayed. However, simple counting of total a emission and the assignment of a predetermined energy to the a particle whose value is prescribed from statistical studies of typically found daughter ratios, allow acceptable accuracies in working-level hour measurements.
