GB/T 11683-1989 in English

《GB/T 11683-1989应急辐射防护用携带式高量程X、γ和β辐射剂量与剂量率仪》由TC30（全国核仪器仪表标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准适用于核事故应急期间测量X、γ和β辐射产生的高剂量或高剂量率的便携式仪器。对X、γ辐射是指自由空气中的空气吸收剂量与剂量率，对β辐射测量是指人体组织深度为7mg/cm2处的组织吸收剂量与剂量率。若采用周围剂量当量(剂量当量率)、定向剂量当量(剂量当量率)或空气比释动能(空气比释动能率)为被测的量，本标准仍适用，但需将约定真值的辐射量由吸收剂量(剂量率)改变为相应的辐射量。本标准适用于对场外实施应急监测的仪器。这种仪器亦可用于应急期间场内的测量。

Scope

This standard specifies the performance and design requirements of portable high-range X, γ and β radiation dose and dose rate meters for emergency radiation protection, including general characteristics, radiation characteristics, electrical characteristics, mechanical characteristics, safety characteristics, environmental characteristics, inspection Programs and Documentation. This standard applies to portable instruments for measuring high doses or high dose rates produced by X, gamma and beta radiation during emergency nuclear accidents. For X and Y radiation, it refers to the air absorbed dose and dose rate in free air. For β radiation measurement, it refers to the tissue absorbed dose and dose rate at a depth of 7 mg/cm² of human tissue. If ambient dose equivalent (dose equivalent rate), directional dose equivalent (dose equivalent rate) or air kerma (air kerma rate) is used as the measured quantity, this standard is still applicable, but the agreed true value of radiation The amount changes from the absorbed dose (dose rate) to the corresponding radiation amount. This standard applies to instruments for emergency monitoring outside the site. This instrument can also be used for in-field measurements during emergencies. This standard also provides a basis for selecting instruments for emergency radiation monitoring, which must be able to provide data reliably and quickly to make timely decisions for emergency actions.
