1 – Time of statistical information accumulation required to obtain measurement
results with estimated limits of statistical deviations equal to the specified limits of
statistical deviations determined by the dosimeter.
2 – Time of statistical information accumulation required to obtain measurement
results with specified limits of statistical deviations equal to the main relative
permissible error limit.
Figure А.2 - Dependence diagram of statistical information accumulation time
required to obtain measurement results with estimated limits of statistical
deviations equal to the main relative permissible error limit (1) and specified limits
of statistical deviations (2) determined by the dosimeter from photon-ionizing
radiation DER when measured by the control unit
