Radiophotoluminescence (RPL) dosimetry using silver-activated phosphate glass has emerged as a key technology for individual monitoring in the 1990s. The defect centres associated with RPL are formed upon radiation exposure in a non-ionizing excitation process.

When the glasses are subsequently exposed to ultraviolet radiation, visible light is emitted with an intensity that is linearly related to the absorbed dose from ionizing radiation. Unlike thermally (TL) or optically stimulated luminescence (OSL), the induced luminescent centres associated with RPL are not destroyed by the normal reading process and are extremely stable, so that fading at room temperature is negligible over a period of several years and the dose information can be obtained repeatedly at any time during long-term dose accumulation.

Participants of the webinar will learn about:

• IAEA GSR Part 3 requirements and GSG-7 guidance for technical service providers for external individual monitoring;
• RPL dosimetry and setting an RPL dosimetry laboratory for individual and workplace monitoring;
• Routine operation of an RPL dosimetry laboratory for individual monitoring;
• Clinical applications of RPL dosimeters;
• Experience of laboratories to deal with the COVID-19 pandemic;
• Experience of the IAEA Radiation Safety Technical Services on characterization of RPL dosimetry system for individual monitoring.

Presenters:

• Yasuhiro Koguchi, Deputy Head of Oarai Research Center, Chiyoda Technol Cooperation in Japan.
• Alain Savary, Head of Metrology and Method Unit of the Department dedicated to the radiological monitoring of workers at the Institute for Radiological Protection and Nuclear Safety (L’Institut de Radioprotection et de Sûreté Nucléaire, IRSN) since 2015.

And Burçin Okyar, Michael Hajek, Roman Abutalipov from IAEA.
