A type of radiation exposure measurement device. An electrometer made of thin fibers is built into a fountain pen-shaped cylinder. A voltage is applied to the fibers in advance, and the fiber is displaced due to discharge caused by ions produced by radiation. Before digital electronic dosimeters using semiconductor detectors became widespread, they were mainly used as personal dosimeters for work management.

放射線に対する被曝線量測定器の一種。細い繊維でつくった電位計を万年筆型の円筒に組み込んだもので,あらかじめ繊維に電圧を与えておき,放射線のつくるイオンによる放電のため,繊条が変位するのを観測する。半導体検出器を使ったデジタル式の電子式線量計が普及する前は,主として作業管理のための個人用線量計として使われていた。
