Summary:To facilitate measurement work of radioactivity concentration (radioactivity strength) of a clearance object.SOLUTION: A clearance measuring device 1 includes: a profile measuring device 2 for measuring radioactivity strength of a clearance object by following a measurement surface; a control device 3 for controlling operation of the profile measuring device; and an evaluation device 4 for evaluating radioactivity concentration of the clearance object. The profile measuring device includes: at least one shape measuring device 12 for measuring a shape of the clearance object; a radiation detector 13 for detecting radiation strength of the clearance object; and a movement mechanism 14 for moving the radiation detector. The control device has a movement control part 20 for controlling operation of the movement mechanism. The movement control part moves the radiation detector following the measurement surface of the clearance object according to the shape of the clearance object measured by the shape measuring device. The evaluation device evaluates radioactivity concentration of the clearance object on the basis of radiation strength detected by the radiation detector.SELECTED DRAWING: Figure 1 【課題】クリアランス物の放射能濃度（放射線強度）の測定作業を容易化する。【解決手段】クリアランス測定装置１は、リアランス物のクリアランス物の放射線強度を測定面に倣って測定する倣い測定装置２と、倣い測定装置の動作を制御する制御装置３と、クリアランス物の放射能濃度を評価する評価装置４と、を備えている。倣い測定装置は、クリアランス物の形状を測定する少なくとも１つ以上の形状測定装置１２と、クリアランス物の放射線強度を検出する放射線検出器１３と、放射線検出器を移動させる移動機構１４と、を有している。制御装置は、移動機構の動作を制御する移動制御部２０を有している。移動制御部は、形状測定装置で測定されたクリアランス物の形状に応じてクリアランス物の測定面に倣って放射線検出器を移動させる。評価装置は、放射線検出器で検出された放射線強度に基づいてクリアランス物の放射能濃度を評価する。【選択図】図１
