The revised JIS Z4511:2018 (X and gamma reference radiation for calibrating dosemeters and doserate meters and for determining their response as a function of photon energy) was published in July 2018. JIS Z4511:2018 is MOD to ISO 4037 part 1 to part 4, and the contents are quite different from the previous document. The several calibration methods are added as informative annex. In this paper, points of difference in new and previous documents are explained.
