This lecture focus on the evaluation of equivalent doses in radiation applications other than the medical field. Equivalent dose limits are established based on the recommendations of the International Commission on Radiological Protection (ICRP) in radiation safety standards of Japan. The equivalent doses of workers are evaluated with the operational quantities defined by the International Commission on Radiation Units and Measurements (ICRU). Domestic safety standards are based on the concept of the ICRP's 1990 recommendations, but data used for dose evaluations in accordance with the 2007 recommendations, which replaced these recommendations, have also been made public. In addition, many issues have been pointed out regarding the use of dose in radiation protection, and ICRP published Publ. 147, which clarifies these issues. Efforts are currently underway internationally to resolve the issues presented here. However, consideration and improvement measures are required about issues clarified in Publ.147 within the current protection system.
