Radiological protection requires the quantification of the extent of exposure of the human body to ionizing radiation. To this end, the International Commission on Radiological Protection (ICRP) and the International Commission on Radiation Units and Measurements (ICRU) developed a dosimetry system consisting of protection quantities and operational quantities. The existing dosimetry system has been successfully used in radiological protection practice and regulations. Nevertheless, the system has some limitations and needs further improvements to consider changes in the fields of radiological protection. ICRP and ICRU have been discussing the issues to propose an alternative system of radiation dosimetry. This presentation overviews recent discussion on the protection quantities and operational quantities by ICRP and ICRU and the proposed dosimetry system for radiological protection.

Japanese translation of ICRP Publication 116 entitled "Conversion Coefficients for Radiological Protection Quantities for External Radiation Exposures" was published by the Japan Radioisotope Association in March 2015. The book gives fluence to dose conversion coefficients for both effective dose and organ absorbed doses for various types of external exposures, consistent with the 2007 Recommendations of the ICRP. A complete set of conversion coefficients is provided in an accompanying CD in ASCII format and Microsoft Excel software. This article overviews ICRP Publication 116 and its impact to practice of radiation protection.

In 2007, the International Commission on Radiological Protection (ICRP) adopted new fundamental recommendations on radiation protection in ICRP Publication 103 (ICRP103). The recommendations revised procedure for the assessment of effective dose used for radiological protection. The revision required new dose conversion coefficients for external radiation exposures. The sets of conversion coefficients were compiled by the Task Group on Dose Calculations (DOCAL) of ICRP Committee 2, and published as ICRP116. This presentation reviews ICRP116 and discusses the impact of new dose conversion coefficients on radiation protection practice.
