Zusammenfassung: | To efficiently inspect a shielding body.SOLUTION: In a relative data acquisition step of a method for inspecting a shielding body 20, dose length relative data showing a correlation between a length L from a radiation source 101 and a dose of radiation is acquired. In a dose reference value acquisition step, a reference value of a dose at each of a plurality of inspection positions M set to a second side of a scheduled installation position is acquired in the case that the radiation source 101 separated to a first side from the scheduled installation position of the shielding body 20 to be installed radiates radiation. The reference value of the dose at each of the plurality of inspection positions M is acquired on the basis of a length L between the radiation source 101 and each of the inspection positions M, and the dose length relative data. In a passing dose detection step, a detector 102 detects a passing dose obtained by causing radiation radiated form the radiation source 101 in a fixed state to pass through the shielding body 20 at each of the plurality of inspection positions M of the second side of the shielding body 20.SELECTED DRAWING: Figure 8
【課題】遮蔽体の検査を効率良く行う。【解決手段】遮蔽体20の検査方法の相関データ取得工程では、放射線源101からの距離Lと放射線の線量との相関を示す線量距離相関データを取得する。線量基準値取得工程では、設置すべき遮蔽体20の設置予定位置から第一側に離間させた放射線源101で放射線を放射した場合に、設置予定位置の第二側に設定される複数の検査位置Mのそれぞれにおける線量の基準値を取得する。複数の検査位置Mのそれぞれにおける線量の基準値の取得は、放射線源101とそれぞれの検査位置Mとの距離L、及び線量距離相関データに基づいて行う。通過線量検出工程では、遮蔽体20の第二側の複数の検査位置Mのそれぞれにおいて、固定状態の放射線源101から放射された放射線が遮蔽体20を通過した通過線量を検出器102により検出する。【選択図】図8 |
