New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 22127 : 2019 ‘Dosimetry with radiophotoluminescent glass dosimeters for dosimetry audit in MV x-ray radiotherapy’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Nuclear Energy for Peaceful Applications Sectional Committee and approval of the Chemical Division Council.

A radiophotoluminescent glass dosimeter (RPLD) is a cumulative radiation dosimeter usually made of silver-activated phosphate glass. The silver atoms act as radiophotoluminescence (RPL) centres excited by ionizing radiation. The number of RPL centres excited is proportional to the absorbed dose to the RPLD.
