Detection unit 101b is based on the predicted value of the count value that comparison information preparing department 101a is obtained and as radioactive ray detection The comparison of the count value (measured value) of the testing result in portion 12, distinguishes the purposes of pipe arrangement P.In addition, when relatively, detection unit 101b The predicted value of the count value that can not be obtained comparison information preparing department 101a is directly used as comparison information.Detection unit 101b can be with The predicted value is multiplied by into predetermined coefficients etc., according to the different purposes of pipe arrangement P, calculate threshold value as comparison information higher limit and Lower limit, compares the testing result of radioactive ray test section 12 whether in the threshold range.
For example, the predicted value of count value when pipe arrangement P is " gas piping " by detection unit 101b is multiplied by predetermined coefficients etc. Threshold value is calculated, when measured value is in the threshold range, it is " gas piping " to distinguish pipe arrangement purposes.Additionally, detection unit 101b The predicted value of count value when can be " water supply pipe " by pipe arrangement P is multiplied by predetermined coefficients etc. to calculate threshold value, works as measured value When in the threshold range, pipe arrangement purposes can be distinguished for " water supply pipe ".And work as measured value not at " gas piping " and When in the threshold range of " water supply pipe " both sides, pipe arrangement purposes can be distinguished for " other pipelines ".Also, detection unit 101b Can represent that the instruction of result of determination is exported to display control unit in display part 105 by corresponding to the display of these purposes 101c。
In addition, when judge pipe arrangement P be, for example, gas piping and water supply pipe in any one when, can be by comparison information Preparing department 101a only calculates the predicted value of the count value of " gas piping ", and detection unit 101b is by count value when " gas piping " Predicted value is multiplied by predetermined coefficients etc. to calculate threshold value, and when measured value is in the threshold range, it is " coal to distinguish the pipe arrangement purposes Feed channel ", when measured value not in the threshold range when, it is " water supply pipe " to distinguish the pipe arrangement purposes.Or with it is above-mentioned Conversely, only calculating the predicted value of the count value of " water supply pipe ", the predicted value of count value when " water supply pipe " is multiplied by Calculating threshold value, when measured value is in the threshold range, it is " water supply pipe " to distinguish the pipe arrangement purposes to predetermined coefficients etc., When measured value not in the threshold range when, it is " gas piping " to distinguish the pipe arrangement purposes.
In addition, though in above-mentioned record, detection unit 101b by the predicted value of count value by being multiplied by the side such as predetermined coefficients Method compares measured value whether in the threshold range calculating threshold value, but can also be taken advantage of measured value by detection unit 101b Threshold value is calculated with predetermined coefficients etc., compares the predicted value of count value whether in the threshold range distinguishing the purposes of pipe arrangement P.
Above-mentioned decision method is only as an example, it is possible to use other decision methods.For example, can be by comparison information preparing department The measured value (testing result) of the count value that 101a is detected based on radioactive ray test section 12, calculates in (seizing back confiscated property) pipe arrangement information and appoints The predicted value of one parameter, predicted values and being somebody's turn to do by input unit 104 direct or indirect input of the detection unit 101b based on the parameter The comparison of the input value of parameter, distinguishes the purposes of pipe arrangement P.
