The pioneer in radiation protection
Chiyoda Technol Corporation is a pioneer in radiation protection, which started the first radiation monitoring service using film badges in Japan in 1954.
In 2000, we succeeded in switching from film to glass and realized the first large-scale monitoring service using glass dosimeters in the world.
The glass dosimeter-based measuring method, which activates fluorescence centers formed by radiation exposure using laser and measures them retrospectively, have been known since the end of World War II. However, these dosimeters had been considered as dream instruments and used only in research institutions because of the high technology barrier for actual use.
Eight years later, our glass dosimeter monitoring system was introduced to the monitoring service of the Institut de radioprotection et de sûreté nucléaire, France, which is one of the most authoritative radiological research institutions in Europe, in high recognition of its uniqueness in the world.
There are many types of glass dosimeters that meet various needs, including small-sized dosimeters characterized by high precision at high doses, which are highly recognized in medical settings, and environmental dosimeters characterized by high precision at low doses, as well as personal dosimeters for radiation workers.
