PROBLEM TO BE SOLVED: To provide a radiation detector capable of calculating an integrated value correctly regardless of intensity of fluorescent light generated on a scintillator.SOLUTION: The radiation detector of the invention can calculate a correct integrated value S regardless of intensity of fluorescent light generated on a scintillator 2. Namely, by adapting the calculation method of the integrated value S like the invention, number of time point intensity data d which are added as the fluorescent light is generated on the scintillator 2 increases as the intensity of the fluorescent light is strong. Therefore, the intensity of the strong fluorescent is not estimated by underestimation. An integration part 15 of the invention can calculates the reliable integrated value S. Because the time point intensity data used for calculation of the integrated value is equal to or more than a threshold a, an S/N ratio is sufficiently high and having high reliability. |
