Radiation protection instrumentation - Passive integrating dosimetry systems for environmental and personal monitoring Part 1: General characteristics and performance requirements
 N EN 62387-1

Annotation

Scope and object

This European Standard applies to all kinds of passive dosimetry systems that are used for measuring

– the personal dose equivalent Hp(10) (for whole body dosimetry),

– the personal dose equivalent Hp(0,07) (for both whole body and extremity dosimetry),or

– the ambient dose equivalent H*(10) (for environmental dosimetry).

It applies to dosimetry systems that measure external photon or beta radiation in the dose range between 0,01 mSv and 10 Sv and in the energy ranges given in the following Table. All the energy values are mean energies with respect to the prevailing dose quantity. The dosimetry systems usually use electronic devices for the data evaluation and thus are often computer controlled.

NOTE 1 In this standard, "dose" means personal or ambient dose equivalent, unless otherwise stated.

NOTE 2 For Hp(10) and H*(10) no beta radiation is considered. Reasons: 1) Hp(10) and H*(10) are a conservative estimate for the effective dose which is not a suitable quantity for beta radiation. 2) No conversion coefficients are available in ICRU 56, ICRU 57 or ISO 6980.

NOTE 3 The maximum energy ranges are the energy limits within which type tests according to this standard are possible.

In addition, this standard can be applied for testing neutron dosimetry systems concerning the design (Clause 8), the instruction manual (Clause 9), the software (Clause 10), environmental influences (Clause 13), electromagnetic influences (Clause 14), mechanical influences (Clause 15), and the documentation (Clause 16). The test utilizing radiation (Clauses 13 to 15) shall be done with neutron reference radiation qualities according to the ISO 8529 series.
