Photon Factory


Regarding the change of personal dose control

March 23, 2023

We would like to inform you that we will not ask you to bring your personal dosimeter any more from April 2023, when you conduct radiation work at Photon Factory. It is because new measuring service in accordance with ISO/IEC 17025 will be introduced, in compliance with the changes in the law in Japan.

Monitoring your radiation exposure will be performed by the dosimeter we provide. But, please note that you should follow the instruction from your affiliation, if there are any. You can check the result of your exposure dose by logging in the "User Portal" system of KEK.

Please remember that you should be certified as a "Radiation Worker" by your institution, as before.
