1 Scope
This document describes procedures for calibrating and determining the response of
dosemeters and dose-rate meters in terms of the operational quantities for radiation
protection purposes defined by the International Commission on Radiation Units and
Measurements (ICRU). However, as noted in ICRU 56 [ 2 ] , the ambient dose equivalent, H *(10), used for area monitoring, and the personal dose equivalent, H p (10), as used for individual monitoring, of strongly penetrating radiation, are not
appropriate quantities for any beta radiation, even that which penetrates 10 mm of
tissue ( E max > 2 MeV).
This document is a guide for those who calibrate protection-level dosemeters and dose-rate
meters with beta-reference radiation and determine their response as a function of
beta-particle energy and angle of incidence. Such measurements can represent part
of a type test during the course of which the effect of other influence quantities
on the response is examined. This document does not cover the in-situ calibration
of fixed, installed area dosemeters. The term “dosemeter” is used as a generic term
denoting any dose or dose-rate meter for individual or area monitoring. In addition
to the description of calibration procedures, this document includes recommendations
for appropriate phantoms and the way to determine appropriate conversion coefficients.
