标准范围

IEC 61526:2024适用于具有以下特性的个人剂量计:a)它们戴在躯干、靠近眼睛或四肢上。b)它们测量来自外部X和γ、中子（不用于Hp（3））和β辐射的个人剂量当量Hp（10）、Hp（3）和Hp（0，07），并且可以测量相同辐射的相应个人剂量当量率（用于报警目的）。c)它们具有数字指示。可以附上也可以不附上该指示。d)除混合式剂量计外，它们具有个人剂量当量或个人剂量当量率的报警功能。对于混合式剂量计，应在相关读出系统中实现个人剂量当量的报警功能。本文件规定了剂量计及其相关读出系统（如果提供）的要求。本文件规定了上述剂量计的一般特性、一般测试程序、辐射特性以及电气、机械、安全和环境特性。与上一版相比，此版本包括以下重大技术变更:a)标题的修改；b)包括眼睛晶状体中剂量的测量量Hp(3)；c)包括皮肤和四肢剂量的测量量Hp(0,07)；d)在主动和被动之间包括剂量计:“混合剂量计”；e)包括软件要求；f)线性要求与IEC 62387协调；g)修订中子能量响应要求。

IEC 61526:2024 applies to personal dosemeters with the following characteristics:
a) They are worn on the trunk, close to the eye, or on the extremities.
b) They measure the personal dose equivalents Hp(10), Hp(3), and Hp(0,07), from external X and gamma, neutron (not for Hp(3)), and beta radiations, and may measure the respective personal dose equivalent rates for the same radiations (for alarming purposes).
c) They have a digital indication. This indication may or may not be attached.
d) They have alarm functions for the personal dose equivalents or personal dose equivalent rates except for hybrid dosemeters. For hybrid dosemeters an alarm function for the personal dose equivalents shall be implemented in the associated readout system.
This document specifies requirements for the dosemeter and, if supplied, for its associated readout system.
This document specifies, for the dosemeters described above, general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and envi-ronmental characteristics.
This edition includes the following significant technical changes with respect to the previous edition:
a) Modification of the title;
b) Inclusion of the measurement quantity for the dose in the lens of the eye, Hp(3);
c) Inclusion of measurement quantity for dose in the skin and extremities, Hp(0,07);
d) Inclusion of dosemeters between active and passive: "hybrid dosemeters";
e) Inclusion of software requirements;
f) Harmonization of requirements for linearity to IEC 62387;
g) Revised neutron energy response requirements.
