scope:

This International Standard is applicable to housed scintillators for registration and spectrometry of alpha-, beta-, gamma-, X-ray and neutron radiation.

Their basic parameters such as a light output and intrinsic resolution are established. This Standard specifies the requirements for the equipment and the methods of defining the basic parameters of housed scintillators, such as:

- The direct method is intended for light output measurement of scintillators on the base of any given scintillation material. The scintillators certified using this method can serve as a working standard of housed scintillators (hereinafter - working standard) when using the method of comparison.

- The method of comparison with the working standard is intended for housed scintillators based on the same scintillation material as the one of the working standard.

The standard does not apply to gas or liquid scintillators and scintillators for counting or current measurement.
