Development of the new glass badge

The glass dosemeter, which is a component of the glass badge (GB), is used on the basis of radiophotoluminescence phenomenon. Chiyoda Technol Corporation has been providing it for personal monitoring services since the year 2000. Through the experience acquired over 15 y, Chiyoda Technol Corporation has developed the New GB, which was brought into service in Japan for radiation monitoring in January 2014. The New GB was developed with the aim of improving radiation measurement methods, streamlining the provision of GB monitoring services and realising a user-friendly dosemeter. As the result, in this study, the measurable energy range covered for beta rays was expanded to include those emitted from 147Pm, the directional dependency was improved, a film was designed to remove secondary electrons arising from interactions between incident photons and the metallic filters, and the arrangement of the metallic filters was optimised.
