Abstract

Atmospheric tritium activity was measured regularly around Kakrapar Atomic Power Station (KAPS) since gaseous waste which contains tritium is being released through a 100 m high stack at KAPS site. Data collected shows a large variation of 3H concentration in air, fluctuating in the range of ≤0.2−19.9 Bq·m−3. Significantly, higher tritium levels were measured in samples at the site boundary (1.6 km) of KAPS compared to off-site locations. The atmospheric dilution factor was found to be in the range of 1.1·10−7–2.9·10−7 s·m−3. The scavenging ratio of KAPS site was found to be varying from 0.4·104 to 16.7·104 (Bq·m−3 rain water per Bq·m−3 air). The inhalation dose to a member of general public at different distances (1.6−30 km) from KAPS site was found to be 0.07 μSv·y−1.
