During maintenance, inspection and modification of equipment, work may be carried out under high radiation conditions. Figure 1 is a schematic diagram of a high radiation flow installation.In the case of a light water reactor (1), workers are affected by radiation emitted from pressure vessels, primary system equipment, piping, etc. Therefore, in order to prevent the exposure dose from exceeding the control value, the worker 2 should use an alarm meter that issues an alarm when a predetermined exposure dose is reached, in addition to a personal exposure measuring device such as a film batch, pocket dosimeter, or thermofluorescence dosimeter. Work while carrying it.
かかる高放射線下の作業では、管理値を超えないまでも
、当初の計画値を超過する場合があり、作業全体の作業
者の線被ばく線量の調整、確認の遅れが問題になる。In such high radiation work, even if the control value is not exceeded, it may exceed the originally planned value, and delays in adjusting and confirming the line exposure dose of workers during the entire work become a problem.

業範囲が限定される等の欠点が生じた。In order to solve these problems, a device has been created that extracts the alarm meter signal and receives and manages the exposure dose of the worker 2 under high radiation dose using radio, but because the shielding wall 3 is thick, The disadvantage was that the signal could not be reached. Another idea was to use a wired device to connect the alarm meter signal to a place outside the shielding wall 3 that is not affected by radiation.
There were disadvantages such as the danger of the worker getting his/her foot caught on the wire and the work range being limited.

のである。In order to achieve the above object, the present invention installs a receiver 4 for receiving a wireless signal emitted from an alarm meter and an A/D conversion signal transmitter 7 inside a radiation shielding wall 3, and transmits the radio signal to a remote location via a penetration part of the shielding wall. The information is transmitted by wire 8 to the CRT 9 of the data bank built into the computer belonging to the exposure dose manager 5.
従って本発明によれば、作業者は作業性を損う（３）
ことなく、放射線量を時々刻々把握しながら安全に作業
することができる。Therefore, according to the present invention, a worker can work safely while grasping the radiation dose from time to time without impairing work efficiency (3).
