Place the УПГД-3В carriage together with the dosimeter in the
position, where DER from
statistical error of DER measurement results goes down to the value of not
more than 10 %. Then register five DER measurement results in the
protocol with 5 s interval.
Calculate the DER value in µSv/h by the formula (1).
Calculate the main relative error of measurement in percentage.
