Tritium content in precipitation and atmospheric water vapour of the reactor hall in the Vinča institute of nuclear sciences

Tritium activity was determined in precipitation samples collected at two locations in Belgrade over the period 1998-2007: meteorological station Belgrade (Zeleno Brdo 44º47' N, 20º32' E, altitude 243.2m asl) and the station at the Vinča Institute of Nuclear Sciences. Tritium concentrations in precipitation ranged from 0.4 to 4.41 Bq l-1 (samples collected at Zeleno Brdo) and from 2.31 to 41.30 Bq l-1 (samples collected at VINS). Tritium content in atmospheric water vapour of the indoor reactor hall and inside of the reactor during the regular inspection of the fuel channels in the Vinča Institute of Nuclear Sciences in March and May 2006 was measured. The obtained results showed that the tritium content in HTO form varied from 1.56x102 Bq m-3 to 4.05x102 Bq m-3.Physical chemistry 2008 : 9th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 24-28 September 200
