RADIATION DOSIMETER AND RADIATION DOSE COMPUTING PROGRAM |
摘要 |
Light emitted in correspondence to ionizing radiation incident from a scintillator (10) is fed through an optical fiber (12) to a photoelectron multiplier tube (14) by which it is converted to an electrical signal. The electrical signal is amplified by a signal amplifying circuit (16), and any light emission events of given or higher intensity are discriminated by a discriminator (18) and counted by a counter. The count value is fed to a computer (22). The computer (22) converts the count value to a dosage on the basis of an exponential relationship lying between the light emission intensity and the number of emission events, thereby attaining detection of the dosage. |
