适用范围

This part of IEC 62387 applies to all kinds of passive dosimetry systems that are used for measuring the personal dose equivalents Hp(10) or Hp(0,07) or the ambient dose equivalent H*(10). 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. This standard is intended to be applied to dosimetry systems that are capable of evaluating doses in the required quantity and unit (Sv) from readout signals in any quantity and unit. The only correction that may be applied to the evaluated dose (indicated value) is the one resulting from natural background radiation using extra dosemeters. NOTE The correction due to natural background may be made before or after the dose calculation. In this standard, requirements are stated for minimal ranges of influence quantities, for example 80 keV to 1,25 MeV for photon energy (see Tables 3 to 5). A dosimetry system shall at least fulfil the requirements stated for these minimal ranges. However, the manufacturer may state larger ranges for the different influence quantities, for example 60 keV to 7 MeV. These larger ranges are called rated ranges. In such cases, the dosimetry systems must fulfil the requirements stated for these rated ranges. Thus, dosimetry systems can be classified by stating a set of ranges (for dose, energy, temperature etc.) within which the requirements stated in this standard are met (Capabilities of the system, see Clause 7). In addition, usage categories are given in Annex D with respect to different measuring capabilities.
