  • Abstract
    An electrometer which uses a single MOSFET as the current-detecting and temperature-compensating element is described. The input drift is less than 3 x 10-15 A from -20°C to +40°C. This electrometer is used in radiological field instruments which have been operating continuously for over a year. It can resolve changes down to 0.1 ¿R/hr (2.5 × 10-15 A) in a background exposure rate of 6-10 ¿R/hr.
