Since 2012, International Standardization Organization TC85/SC2 Working Group 19 dealing with 'Individual monitoring for external radiations' has been conducting important work revising the 21909 standard on passive personal neutron dosemeters. A consensus in the community acted that the 2005 version( 1) needed to be revised for two main reasons: (1) to achieve a document applicable to all systems irrespectively to the considered techniques and (2) to reach harmonisation between performance tests and conditions of use at the workplaces. The document was completely rewritten to be binding enough to ensure that any neutron dosimetry system fulfilling the criteria would be reliable in most of the usual work situations, in terms of dose level, energy and direction distributions of the neutron fluence. This paper explains the reasons behind the revision and the new philosophy of the series published in 2021, so that Individual Monitoring Services may better understand how to apply the requirements in practice.
自 2012 年以来，国际标准化组织（ISO）TC85/SC2 工作组 19 一直在进行修订“个人外照射监测”的 21909 号标准的重要工作。社会上达成共识，认为有两个主要原因需要修订 2005 年版（1）：（1）实现一份适用于所有系统的文件，而不考虑所考虑的技术；（2）实现工作场所的性能测试和使用条件之间的协调。该文件经过全面重写，具有足够的约束力，以确保任何满足标准的中子剂量计系统在大多数常见工作情况下，在剂量水平、中子注量的能量和方向分布方面都具有可靠性。本文解释了修订的原因以及 2021 年发布的系列标准的新理念，以便个人监测服务机构能够更好地理解如何在实践中应用这些要求。
