Tritium in environmental objects in the area affected by FSUE Mayak Production Association in 2014 –15

Comparison of tritium volume activity (VA) rates in objects of environment in the Mayak Production Association (Mayak PA) affected area in the period from 2014 to 2015 with tritium VA rates in the same or similar objects of environment measured in the period from 2001 to 2013. Water samples from environmental objects —precipitations, ponds, wells—were the material for this research. Tritium VA in various environmental objects was measured using liquid scintillation method. The results were processed using parametric and nonparametric methods of statistical analysis. In samples collected in 2014 –15 from open reservoirs located in Mayak PA affected area tritium VA was 1.4 times lower than the level of tritium VA in water samples from the same reservoirs collected in 2001 –03. There was no statistically significant difference between tritium VA in water samples from the same open reservoirs collected in periods 2009 –12 and 2014–15. Tritium VA in the water sample from production reser...
