This Standard specifies the scintillation type radiation meters used for measuring the activity concentration of gamma-emitting radionuclides in food/foodstuffs (hereafter referred to as "radiation meters") under field conditions where radioactive substances have spread due to the nuclear reactor accident, etc.
It does not apply to the low background stationary radioactivity analysis equipment such as a germanium gamma -ray detector used in specialized agencies for analysis.
In addition, this Standard is applicable also to the measurement of environmental samples in general such as soil, sewage, plant and animal life.
NOTE 1 The pretreatment method of samples is not covered by this Standard.
NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
lEC 61563 : 2001 Radiation protection instrumentation – Equipment for measuring specific activity of gamma-emitting radionuclides in foodstuffs (MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
