Abstract

Data on131I concentration in the atmosphere of Prague observed during the first days after the Chernobyl accident are presented. The sampling device enabling the differentiation between aerosol-fixed and gaseous form of131I is briefly described. The highest total131I concentration, 63 Bq.m−3, was observed between 30 April and 1 May. Until 9 May the level of131I activity ranged between 14 and 1 Bq.m−3 and then dropped below 1 Bq.m−3. The content of gaseous131I was found to be a significant and represented on average 60–80% of its total activity.
