BS IEC 61275 is an international electrotechnical commission standard on radiation protection instrumentation that discusses the measurement of discrete radionuclides in the environment to ensure protection against radiation hazards.
BS IEC 61275 is applicable to a portable or transportable photon spectrometry assembly using a high purity germanium (HPGe) detector to survey, in situ, at 1 m above ground level, areas in the environment for discrete radionuclides. Such equipment is used to make rapid assessments of activity levels and corresponding free air exposure rates from photon emitting radionuclides.
These measurements may be used to develop guidance for subsequent follow-up action, for example including radiological assessments, sampling, and monitoring programmes.
BS IEC 61275 specifies for such an assembly the general characteristics and test methods for evaluating radiation, electrical, mechanical, safety and environmental characteristics specific to the applications described above. Advice is also provided in annexes as to the calibration, appropriate use and interpretation of the system for in situ measurements.
The purpose of BS IEC 61275 is to specify the performance characteristics of assemblies intended for the determination of surface soil activity.
Accordingly, BS IEC 61275
BS IEC 61275 on in-situ spectrometry system for measuring discrete radionuclides is useful for:
An In-situ spectrometry system is a combination of instruments or assemblies designed to measure, in situ, the fluence of the gamma-ray incident on the detector, to rapidly survey areas for discrete radionuclides present in the soil or air, either natural or manmade.
BS IEC 61275 provides you with guidance on general requirements, classification of the performance characteristics, general characteristics, effective range of measurement of an assembly, general test procedures, radiation tests and assembly characteristics.
The requirements, test methods and procedures provided by BS IEC 61275 assist you in improving the performance and quality of the in-situ spectrometry system for measuring discrete radionuclides in the environment and ensure protection against severe health issues due to exposure to radiation.
With obedience and compliance to BS IEC 61275, you can enhance in-situ spectrometry systems’ efficacy and manufacture a standardized product.
BS IEC 61275:2013 supersedes IEC 61275:1997 which is withdrawn. BS IEC 61275:2013 has made some technical changes compared to the previous editions IEC 61275:1997. These include:
