International Standards on Food and Environmental Radioactivity Measurement for Radiological Protection: Status and Perspectives

Abstract

Radiological protection is a matter of concern for members of the public and thus national authorities are more likely to trust the quality of radioactivity data provided by accredited laboratories using common standards. Normative approach based on international standards aims to ensure the accuracy or validity of the test result through calibrations and measurements traceable to the International System of Units. This approach guarantees that radioactivity test results on the same types of samples are comparable over time and space as well as between different testing laboratories. Today, testing laboratories involved in radioactivity measurement have a set of more than 150 international standards to help them perform their work. Most of them are published by the International Standardization Organization (ISO) and the International Electrotechnical Commission (IEC). This paper reviews the most essential ISO standards that give guidance to testing laboratories at different stages from sampling planning to the transmission of the test report to their customers, summarizes recent activities and achievements and present the perspectives on new standards under development by the ISO Working Groups dealing with radioactivity measurement in connection with radiological protection.

Radiation protection among health care workers: knowledge, attitude, practice, and clinical recommendations: a systematic review

“…Specifically, the HCWs exposed to radiation develop cancer by approximately more than 40% compared to patients and other groups [7]. To prevent the side effects of radiation, the International Radiation Protection Association (IRPA) has designed some guidelines to limit the dose received by the HCWs, and it is periodically reviewed [8,9]. The most important method of proper radiation protection principle implementation is education [10].…”

Uncertainty, Detectability and Conformity in Measurements of Ionizing Radiation

“…6) The methodology provided by these guides and ISO 11929 has been taken into account also in a number of ISO standards dealing with environmental radiation measurements; see e.g. CALMET 7) and CALMET et al 8) for surveys. This paper summarizes some basics of the underlying methodology and gives some guidance for the practical application.…”
