Abstract With the continuous progress in the radiation protection, the international standards related to ionizing radiation dosimeters are also continuously updated and iterated.In order to summarize the development status of IEC and ISO standards in the field and provide reference for the production and selection of dosimeters, by researching and comparing the content of different versions of relevant standards, summarizing the development overview of relevant IEC and ISO standards and the modifications and updates made in the latest version for the dose monitoring instruments of photon, β and neutron, as well as the differences in performance requirements and specifications for various aspects of instruments between the different current standards were compared.It was found that the international standards under each monitoring category tended to be unified in the development process, no longer divided by detector types, etc.Moreover, the overall application scope of these standards was broader, but the relevant standards of dose measurement instruments for pulsed radiation still need to be developed.And different standards applicable to the same monitoring classification had basically the same performance requirements for instruments, however, due to the different purposes and application scenarios of IEC and ISO standards, there were differences in the focus of performance requirements and specifications between the two.
