Title: Method and device for measuring integral irradiation dosage of radiation
Inventor: NAKAMURA SHIGEKI
IPC: G01T1/02
Filed: 1987-04-01
Abstract: PURPOSE:To obtain a high-accuracy, wide-range measuring method at low cost by irradiating a silicon diode with radiation, storing an output current corresponding to its irradiation dosage in a potential storage element as the quantity of electricity, and detecting it as a voltage in a safe place. CONSTITUTION:While a switch 31 and a voltmeter 33 are disconnected from measurement electrodes 27 and 29, the silicon diode 23 and potential storage element 25 are put hermetically in a waterproof or dampproof container and irradiated with the radiation. When the silicon diode 23 absorbs the radiation, an ionization current flows in the silicon diode 23 and is charged in the potential storage element 25. In this state, even if the irradiation of the radiation is stopped, the silicon diode 23 has high insulation and charges in the potential storage element 25 are not discharged. Consequently, the voltage of the potential storage element 25 is detected while the element is put in a safe place after the radiation irradiation to obtain the high-accuracy, wide-range measuring method at low cost.
