Prepare the radiometer for photon-ionizing radiation DER measurement
(hereinafter called DER) according to item 2.3.3.6 of the OM. Program 3 % value
of the specified limit of statistical deviations.
Place the УПГД-3В carriage together with the radiometer in the position, where
Cs source is 800 μSv/h, and wait until the estimated level of statistical
137
DER from
deviations of DER measurement results goes down to the value of not more than
3 %. Then enter five DER measurement results with 5 s interval in the report.
Calculate the average DER value and the main relative error during
measurement, expressed as a percentage, according to the recommendations of
DSTU GOST 8.207:2008 standard.
The radiometer is acknowledged to have passed the verification if the relative
main error in percentage when measuring DER does not exceed 15+2/M,
where M is a dimensionless value that is numerically equal to the value of measured
DER in μSv/h.
