This standard applies to apparatus for the non-destructive measurement of radioactive contamination of fur and cloth samples for the presence of gamma emitting radionuclides. The apparatus is designed for the testing of samples of differing weights and dimensions and may consist of the following parts: – device for sample radioactivity measurement; – auxiliary equipment for sample weight and dimension determination. The tests of cloth for nuclides emitting only alpha and low energy beta (Emax less than 150 keV) particles are not considered in this standard as the radiation from these nuclides present no risk from external radiation. This standard however may be applied to apparatus for the testing of cloth for the presence of beta emitting radionuclides (the beta radiation having an Emax greater than 150 keV). The object of this standard is to define mechanical and operational characteristics, minimum performance characteristics and general test procedures for equipment for the testing of fur and cloth samples.
