Determination of gross α and ß radioactivity of drinking water in a district in Shanghai

Objective To investigate the radioactive level of gross alpha and beta in drinking water in one district in Shanghai and provide a scientific basis for measuring the level of radiation in case of drinking water pollution due to potential nuclear accidents.

Methods A total of154 samples collected across the district were monitored by using the standard examination method for drinking water - radiological parameters GB/T 5750.13-2006.

Results All the samples of the drinking water conformed to the standard for drinking water quality GB 5749-2006. The differences between different seasons were significant. The difference of gross alpha and beta radioactivity of drinking water was significant between the high water period and the dry water period. The former was higher than the latter.

Conclusion It is very important to monitor and study radioactivity of drinking water regularly for the prevention and control of health damage caused by radioactive water pollution.
