This 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(3) (for eye lens dosimetry),

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

  • the ambient dose equivalent  H*(10) (for environmental dosimetry), or

  • the directional dose equivalent H’(0,07) (for environmental dosimetry).

This standard applies to dosimetry systems that measure external photon and/or beta radiation in the dose range between 0,01 mSv and 10 Sv and in the energy ranges given in Table 1. 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.

Table 1
Mandatory and maximum energy ranges covered by this standard

[This table has been removed.]

a

The following beta radiation source are suggested for the different mean energies: For 0,06 MeV: 147Pm; for 0,8 MeV: 90Sr/ 90Y; for 1,2 Mev: 106Ru/ 106Rh.

b

For beta-particle radiation, an energy of 0,7 MeV is required to reach the radiation sensitive layers of the eye lens in a depth of about 3 mm (approximately 3 mm of ICRU tissue).

c

For beta-particle radiation, an energy of 0,07 MeV is required to penetrate the dead layer of skin of 0,07 mm (approximately 0,07 mm of ICRU tissue).

NOTE 2

In this standard, “dose” means dose equivalent, unless otherwise stated.

NOTE 3

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 6980‑3 .

NOTE 4

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

The test methods 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) are independent of the type of radiation. Therefore, they can also be applied to other dosimetry systems, e.g. for neutrons, utilizing the corresponding type of radiation for testing.

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 5

The correction due to natural background can be made before or after the dose calculation.
