5.4 Verification Officers Qualification Requirements
5.4.1 Only persons certified as state verification officers in accordance with established pro-
cedure are allowed to conduct measurements during verification and (or) to analyze measurement
results.
5.5 Safety Requirements
5.5.1 Any works with radioactive sources must be done according to state and local safety
instructions for radioactive sources and other ionizing radiation sources valid at the verification site.
The verification process should be considered as work under special conditions.
5.6 Verification Conditions
5.6.1 Instrument verification is carried under normal environmental conditions:
- ambient air temperature (20 5) С;
- relative air humidity 60 (+20; -30) %;
- atmospheric pressure 101.3 (+5.4; -15.3) kPa;
- external gamma background radiation no more than 0.2 μSv/h.
