Measurement of radioiodine in Purex stack gases
The chemical behavior of iodine-131 in stack air from this site's Purex process is reported. The radioiodine in the stack gases apparently consists of variable proportions of molecular vapor and other forms of iodine, thus causing the efficiencies for most collection media to vary widely. Activated charcoal is a satisfactory collection medium although Process gases (ammonia and oxides of nitrogen) lower the efficiency of the charcoal from 99 to 88%. Ambient temperature and humidity had no effect on deposition and retention of iodine in long stainless steel sampling lines. Process conditions did have an effect and estimates of iodine released were 10 to 15% low due to this line loss. (auth)
