Description

The results are reported of a laboratory study into the static and dynamic ageing of adsorbent GA-J for iodine filters in nuclear power plants. The adsorbent ageing was assessed using the standard test of the efficiency of capture of 131I-labelled CH3I. It was found that the reduction in adsorbent efficiency due to static ageing was insignificant (approx. 2% per year) while the efficiency reduction due to dynamic ageing was marked. It was about 40% over one year of exposure to ambient air and was mainly due to adsorbent poisoning. (author)
