- Scope
- This standard specifies the analysis method for 226Ra/228Ra activity ratio in geological water samples, where 226Ra is measured by emanation method, and 228Ra is measured by its subscript Body 228Ac was measured on a low background beta device. This standard is applicable to the analysis of 226 Ra and 228 Ra activity ratio in surface water, groundwater, uranium pit water and uranium factory wastewater. Environmental sewage, seawater and solid samples can also be used as a reference after corresponding treatment. Measuring range: 226Ra specific activity>3.6×10-3Bq/L and 228Ra specific activity>3.5×10-3Bq/L Various ratios.
