PROBLEM TO BE SOLVED: To provide a contamination inspection device that can accurately find the degree of radioactive contamination of an object to be measured even when the degree is converted into a surface contamination density, by obtaining a more detailed distribution than the width of a detector without lowering the sensitivity of a radiation detecting means. SOLUTION: This contamination inspection device is provided with the radiation detecting means 1; a radiation counting means 2 constituted of an amplifier, a counter, a computer or multi-channel scaler which reads out and stores counted values, etc.; and a discrete value integrating means 3. This device is also provided with an activity and contamination density converting means 4, a contamination distribution displaying means 5, and a transporting speed and counting time control means 6 which sets and controls the transporting speed of the object to be measured and counting time intervals. In addition, this device is also provided with an object-to-be-measured transporting means 7. COPYRIGHT: (C)2004,JPO&NCIPI
