Scope

This Standard specifies the radiological protection requirements and safety requirements of
detection instruments of source container and sealed radioactive source (hereinafter referred as
“sealed source”); and requirements of radiological protection testing and inspection.
This Standard is applicable to those detection instruments with sealed source and based on
particle fluence measurement (hereinafter referred as “detection instrument”); such as the level
gage, densimeter, hygrometer and nuclear scale.
