- Scope
- This standard specifies the measurement method of in-situ high-purity germanium spectrometer for measuring nuclide radioactivity concentration and radioactive fallout ash deposition flux in soil. This standard is applicable to the determination of artificial radioactive nuclides in surface soil during emergency monitoring of nuclear accidents. Radiation environment quality monitoring can be implemented as a reference. For newly settled radioactive fallout ash, the lower detection limit of 137Cs activity concentration measured by this standard is 100 Bq/m2. 2
