Signal processing method, signal processing device, and radiation detection apparatus

A signal processing method, comprising:

• calculating a noise level included in a signal including a step wave generated in response to detection of radiation, or a slope of a non-response line which is included in the signal and is a part other than the step wave;
• measuring a wave height of the step wave;
• and
• correcting the wave height according to the noise level or the slope.

A signal processing device, by comprising:

• an information processing unit;
• a wave height measurement unit configured to measure a wave height of a step wave generated in response to detection of radiation;
• a counting unit configured to count the step wave, wherein
• the information processing unit calculates a noise level included in a signal including the step wave, or a slope of a non-response line which is included in the signal and is a part other than the step wave,
• the information processing unit corrects the wave height according to the noise level or the slope, and
• the counting unit counts the step wave for each corrected wave height.

A radiation detection apparatus, comprising:

• a radiation detector configured to generate a step wave in response to incidence of radiation and output a signal including the step wave;
• an information processing unit;
• a wave height measurement unit configured to measure a wave height of the step wave;
• a counting unit configured to count the step wave;
• and
• a spectrum generation unit configured to generate a spectrum of the radiation based on a number counted by the counting unit, wherein
• the information processing unit calculates a noise level included in the signal, or a slope of a non-response line which is included in the signal and is a part other than the step wave,
• the information processing unit corrects the wave height according to the noise level or the slope, and
• the counting unit counts the step wave for each corrected wave height.
