Synosis Points
1
In the context of increasing use of radiation and radioactive substances across multiple sectors, there is rising concern about health risks and public perception. These concerns underscore the importance of continuously monitoring radiation exposures, evaluating trends, and assessing their relative impacts on both the public and workers.
2
To ensure that radioactivity monitoring data are reliable, comparable, and fit for their intended purposes, it is essential to agree upon standardized methods for sampling, handling, preparation, and measurement. Such standards help maintain measurement consistency over time and enable laboratories to demonstrate technical competence, particularly in proficiency tests and accreditation processes.

This document outlines a method for determining the activity concentration of beta-emitting radionuclides using liquid scintillation counting (LSC). The technique involves preparing a scintillation source by combining the test sample with a scintillation cocktail, enabling the detection of beta radiation through light emissions. Test samples may be in various forms, including liquids (aqueous or organic) or solids (such as particles, filters, or planchets).
