<p>PROBLEM TO BE SOLVED: To hold a dosimeter vertically to the incident direction of radiation to take a correct measurement by fixing a rotating shaft to the upper end part of the rear face of a capsule holder, and rotatably installing a clip on the rotating shaft. SOLUTION: In a dosimeter holder for holding a portable dosimeter, a rotating shaft 16 is fixed to the upper end part of a rear face of a capsule holder 15 in the lateral direction of the capsule holder 15. A clip 17 is rotatably installed on the rotating shaft 16. When a worker takes a posture of tilting forward, even if the clip 17 tilts, the capsule holder 15 keeps the vertical state to the horizontal plane by its dead load because the clip 17 is rotatably installed on the rotating shaft 16 provided on the capsule holder 15. Accordingly, radiation from a radiation source placed in front of the worker irradiates vertically to the capsule holder 15.</p> |
