RADIATION MEASUREMENT DEVICE |
摘要 |
In a radiation measurement device in which respective wave height values of voltage pulses from a radiation detector are made to correspond to radiation energy values and a count that is the number of the voltage pulses is separately generated for each of a plurality of channels corresponding to the wave height values so that a wave height spectrum is generated and a dose of a radiation that has entered the radiation detector is calculated based on the wave height spectrum, based on a count in at least one channel, out of the plurality of channels, that includes a lower limit within a measurement range for the radiation energy value, a dose is corrected by calculating a portion thereof neglected as what is the same as or smaller than a measurement limit, so that a dose of a radiation that has entered the radiation detector is calculated. |

1. A radiation measurement device comprising a calculation unit in which respective wave height values of voltage pulses from a radiation detector are made to correspond to radiation energy values and a count that is the number of the voltage pulses is separately generated for each of a plurality of channels corresponding to the wave height values so that a wave height spectrum is generated and a dose of a radiation that has entered the radiation detector is calculated based on the wave height spectrum, wherein the calculation unit, based on a count in at least one channel, out of the plurality of channels, that includes a lower limit within a measurement range for the radiation energy value, and based on an energy resolution of the radiation detector, corrects a dose by calculating a portion thereof neglected as what is the same as or smaller than a measurement limit, so as to calculate a dose of a radiation that has entered the radiation detector. |
