Investigating the variation of I-131 concentration in the breathing air at the distillation area

Abstract

Based on the analysis of I-131 concentration and yield over time, this research indicated that the concentrations in the indoor air at the operating area varied over a wide range. In addition, the concentrations and the yields were weakly correlated. This result will help the radiation workers avoid the risks of internal radiation contamination at the distillation area.

Keywords: I-131 concentration; air sample; internal radiation contamination.
