Abstract Objective To investigate the total alpha and total beta radioactivity levels in source water in the areas with three nuclear facilities in Sichuan Province, and provide baseline database for radioactivity level in source water in the areas with nuclear facilities.Methods According to the national standard "Standard examination methods for drinking water-Radiological parameters"(GB/T 5750.13-2006),the total alpha and total beta radioactivity in source water in the areas with three nuclear facilities in Sichuan province were investigated.Results The total alpha activity in source water in the areas ranged from 0.016 Bq/L to 0.188 Bq/L, andthe total beta activity was in a range of 0.028~0.229 Bq/L. Both the levels of total alpha and total beta activity were at the national average middle and lower levels. They still belong to the normal background levels.Conclusion The levels of total alpha and total beta radioactivity in source water in the areas with three nuclear facilities are lower than the national standard set for drinking water quality (GB 5749-2006).
