Temporal distribution of tritium in the atmospheric environment of Mumbai
- 1. Environmental Studies Section, Health Physics Division, Bhabha Atomic Research Centre, Mumbai (India)
Description
Atmospheric Tritium level in the air moisture around Mumbai was estimated at several locations covering a radial distance of 20 km from the discharge point of CIRUS at BARC. Samples were collected by cold finger method from selected locations at 1 meter above ground level from 1.6 km to 20 km radial distance over a period of 3 years 2007-2009; during pre-monsoon, monsoon and post-monsoon seasons. Tritium was estimated in the air moisture by Ultra Low level Liquid Scintillation Spectrometer. The minimum detectable limit for the air moisture samples was 0.02 Eq/m3. Air tritium level was found to be maximum at the nearby locations during monsoon. However, during post-monsoon season the levels were higher at distances >3 km. In general, tritium level in the atmospheric air was in the range of 0.02-2.29 Bq/m3. The dose due to inhalation was observed to be in the range of 8.66E-8 to 9.9E-6 Sv/y which is very much lower than the prescribed limit. (author)
