Transportable Automated Iodine-131 and Xenon-133 Sampling System

Abstract

The fission products Iodine-131 and Xenon-133 from medical radioisotope production waste at Atomic Energy Canada Ltd’s (AECL) Chalk River Laboratories (CRL) are monitored under AECL’s Environmental Protection Plan. At site, most radioactive waste monitoring is done automatically, however a portable system is being developed to gather information about possible localized emissions and support continuous improvements in the emission monitoring program. Considering the operator exposure time to radiation and measurement limitations caused by manual operations, the sampling system has been fully automated. This paper outlines the design and development of the Transportable Automated Iodine and Xenon Sampling System. This system features a fully automated instrument with configuration flexibility, sampling repeatability, reduced operator exposure time to radiation and ease of transportability.
