VERIFICATION TECHNIQUE
Attention! The present verification technique is used for the wrist gamma
dosimeter PM1603, the verification of PM1603A and PM1603B modifications of
PM1603 dosimeter is carried out according to this verification technique. The
verification should be carried out in accordance with the items of verification
technique which are relevant to the present dosimeter modification.
А.1 Introduction
This verification technique extends to wrist gamma dosimeters PM1603, PM1603A
PM1603B, corresponds to the Methodical Instructions 1788 "Radiation-monitoring devices
for measuring the exposure dose and exposure dose rate, absorbed dose and absorbed
dose rate of photon radiation in air. Verification technique" and establishes the verification
technique for dosimeters.
The verification should be carried out by local bodies of the metrological department
of the State Standard Committee and by institutions authorized to carry out these works.
The verification of a dosimeter should be carried out when releasing for sale, when
releasing from repair and during operation and storage with a time interval of 12 months.
