title: [Dosimetry using a silicon diode and an electrochemical integrator].
abstract: A diode-dosimeter constructed from a silicon diode and an MD1B2 "Memoriode" (an electrochemical integrator manufactured by Sanyo Electric Corporation) has been tested to use it for 60Co gamma rays. In this dosimeter, the diode acts as a radiation-to-current converter and the Memoriode as a current integrator, thus the total exposure being known by the terminal voltage on the Memoriode. The response, i.e. radiation-induced terminal voltage on the Memoriode of the dosimeter as a function of exposure, has shown good linearity within the dose-range of one to two decades for every diode. This dosimeter has been found to be useful for measuring exposures between 260 mC/kg (10(3) R) and 2.6 kC/kg (10(7) R) by using replacement diodes with different sensitivities.
