BS EN 61526:2007 Radiation protection instrumentation - Measurement of personal dose equivalents Hp(10) and Hp(0,07) for X, gamma, neutron and beta radiations - Direct reading personal dose equivalent meters and monitors
This International Standard applies to personal dose equivalent meters with the following
characteristics:
a) They are worn on the trunk or the extremities of the body.
b) They measure the personal dose equivalents Hp (10) and Hp (0,07) from external X and
gamma, neutron and beta radiations, and may measure the personal dose equivalent
rates H& p (10) and H& p (0,07) .
c) They have a digital indication.
d) They may have alarm functions for the personal dose equivalents or personal dose
equivalent rates.
This standard is therefore applicable to the measurement of the following combinations of
dose quantities (including the respective dose rates) and radiation
1) Hp(10) and Hp(0,07) from X and gamma radiations;
2) Hp(10) and Hp(0,07) from X, gamma and beta radiations;
3) Hp(10) from X and gamma radiations;
4) Hp(10) from neutron radiations;
5) Hp(10) from X, gamma and neutron radiations;
6) Hp(0,07) from X, gamma and beta radiations.
This standard specifies, for the dosemeters described above, general characteristics, general
test procedures, radiation characteristics as well as electrical, mechanical, safety and environmental
characteristics. The only requirements specified for associated readout systems
are those which affect its accuracy of readout of the personal dose equivalent and alarm
settings and those which concern the influence of the reader on the dosemeter.
This standard also specifies classes of personal dose equivalent meters in relation to
retention of stored information (see 6.1). In addition, usage categories are given in Annex ZA
with respect to different measuring capabilities.
This standard does not cover special requirements for accidental or emergency dosimetry
although the dosemeters may be used for this purpose. The standard does not apply to
dosemeters used for measurement of pulsed radiation where the dose rate in the pulse
exceeds the specification such as that emanating from linear accelerators or similar
equipment.
