Claim:
1. A radiation analyzing apparatus comprising: a superconductive transition edge sensor configured to detect radiation; a spectrum generation unit configured to generate an energy spectrum of the radiation using a detection signal which is output from the superconductive transition edge sensor; a data acquisition unit configured to acquire a physical quantity of data having correlation with detection sensitivity of the superconductive transition edge sensor; and a sensitivity correction unit configured to associate the detection signal output from the superconductive transition edge sensor at a certain timing with the physical quantity of a plurality of pieces of data acquired by the data acquisition unit at a plurality of different timings over a predetermined period of time and to correct the detection signal output at said certain timing in accordance with the detection sensitivity of the superconductive transition edge sensor by using information regarding correlation between the physical quantity of the plurality of pieces of data and the detection sensitivity of the superconductive transition edge sensor, wherein the sensitivity correction unit is configured to correct the detection signal at said certain timing in accordance with the detection sensitivity of the superconductive transition edge sensor by using the information regarding correlation between average value of the physical quantity of the plurality of pieces of data and the detection sensitivity of the superconductive transition edge sensor.
