more than 10 %. Then register five DER measurement results in the
protocol with 5 s interval.
Calculate the average DER value and the main relative error of
measurement in percentage.
The dosimeter is acknowledged to have passed the verification if the
main relative error in percentage during measurement of each DER level
does not exceed
measured DER in µSv/h.
3.2.4.4 Calculation of main relative error of photon-ionizing
radiation DE measurement
Prepare the dosimeter for photon-ionizing radiation DE measurement
according to item 2.3.3.8 of the OM.
Prepare the УПГД-3В testing equipment for operation according to its
operating manual.
Fix the dosimeter in the УПГД-3В carriage holder so that the
mechanical center of gamma beam coincides with the center of the detector.
