Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 13161-2003 "Direct reading personal X and gamma radiation dose equivalent and dose equivalent rate monitor" and GB/T 14323-1993 "X, gamma radiation personal alarm device", compared with GB/T 13161-2003 and GB/T 14323-1993 main technology the changes are as follows.

--- Integrate different instrument standards for different types of radiation (X, gamma, neutron and beta radiation) into one standard, extending the standard Range of use;

--- Electromagnetic compatibility performance requirements and tests increase RF electromagnetic fields, conducted disturbances caused by fast transients or bursts, induced by surges Conducted disturbances, conducted disturbances caused by radio frequency, 50 Hz magnetic field, voltage sag and short interruptions;

--- Mechanical performance requirements and tests have increased the flutter test;

--- Added "uncertainty" content;

--- Removed "storage, transportation, packaging, signs".

This standard uses the translation method equivalent to the use of IEC 61526:2010 "radiation protection equipment to measure X, gamma, neutron and beta radiation personal dose when Volume Hp (10) and Hp (0.07) Direct Reading Personal Dose Equivalent Apparatus.

The individual doses are equivalent to Hp (10) and Hp (0.07).

For personal dose equivalent Hp (10) or personal dose equivalent rate H p(10) and X and gamma radiation give the two minimums of photon energy Rated range. The first rated range is 20keV~150keV for workplaces using low energy X-rays (eg medical diagnosis), Two rated ranges from 80 keV to 1.5 MeV are used in workplaces where high energy X-rays and/or gamma sources are used (eg industrial). For neutrons Radiation, the minimum rated range of neutron energy is 0.025 eV (thermal neutron) ~ 5 MeV. The rated range can be extended to different radiation field related targets all energy that is covered.

For individual dose equivalents Hp (0.07) and X and gamma radiation, the minimum rated range of photon energy is 20 keV to 150 keV, for beta radiation, the minimum rating range is 0.2 MeV to 0.8 MeV. The rated range can be extended to cover different radiation field related standards Have energy.

Examples of extended nominal ranges are given in Appendix C.

In some applications (eg 6 MaiV photon radiation in the vicinity of a nuclear reactor), it is desirable to measure photon energy up to 10 MeV Personal dose equivalent (rate) Hp (10). In some other applications, it is desirable to measure Hp(10) down to 10 keV.

For personal dose equivalents, it is required to measure the dose values Hp(10) and Hp(0.07) and give the dose rate value H for monitoring.

GB/T 2900.81-2008, GB/T 2900.82-2008, GB/T 6592-2010 and ICRUREPORT 51..1993 and the following terms and definitions apply to this document.

Acceptance test acceptance test in order to prove to the customer that the instrument meets the contract test requirements specified in its specifications.

Calibration (for this standard) calibration(forthepurposeofthisstandard) Quantitatively determine the parameters under a controllable standard test condition where all m relative response values rq are 1 and all l deviations Dp are 0.

The relationship between the calibration factor N0 and the nonlinear response correction value rn is examined.

Calibration factor Under the specified reference conditions, the ratio of the agreed true value Hr of the specified reference radiation at the test point to the indicated value Gr. Expressed as.

Note 1. (See GB/T 12162.3-2004) When the dosimeter indication is measured, the calibration factor N is dimensionless. The dosimeter accurately indicates the agreed true value when the calibration factor is 1.

Note 2. (see GB/T 12162.3-2004) The reciprocal of the calibration factor is equal to the response under the reference conditions. The calibration factor is only relative to the reference condition, and the ringing it should be possible to target any conditions at the time of measurement.

Note 3. (See GB/T 12162.3-2004) The value of the calibration factor may vary with the measured value. At this point the doser is said to have a non-linear response.

Coefficient of variation the ratio of the standard deviation s of a set of n measured values xi to its arithmetic mean x.

Note. The calibration results are only valid for this detector unit.

Example. Calibrate a personal dosimeter using a phantom. The personal dosimeter and phantom and the combination of the readout instrument and the cable form a detector device.

In the formula.

G --- the indicated value of the affected quantity;

Gr --- indication value under reference conditions.

Note 1. This term is derived from 311-07-03 "Changes in the amount of influence" in GB/T 2900.77-2008, in order to avoid confusion (changes in (indicative values)" and "changes in response", which is referred to as "deviation" in this standard.
