Radiation protection instrumentation – Passive integrating dosimetry systems for personal and environmental monitoring of photon and beta radiation - Edition 1.0
 N 62387

Annotation

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).

NOTE 1 The term "environmental dosimetry" means ambient, area, and environmental monitoring in this standard.

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. 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 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.
