Description
The present paper is aimed at studying the decrease in workplace contamination with tritium after removal of the neutron generator. The values of volume activity (in the near vicinity of the institute) decreased from about 400 Bq m-3 to the level about 20 Bq m-3 of the air. This value is however by three orders of magnitude higher than present background concentrations of tritium in ground level air of Prague. In the monitored period of the highest contamination the limit of tritium concentration in the atmosphere valid that time for workers handling ionizing radiation was not exceeded, its value being 1.8 x 105 Bq m-3. The highest measured concentration in the radioisotope storage room, which was entered only occasionally, reached only 25% of the mentioned limit. (author)
