A space qualified integrating radiation dosimeter, using a special extra-sensitive metal-oxide-semiconductor (named the TOT 201 transistor) as the sensing device has been put into geostationary orbit aboard a European communication satellite (OTS). This paper describes the fabrication and calibration of a specially sensitive MOS transistor (Sensitivity of 3.8x10(exp-4)Volt rad(exp-1) and the design and calibration of the flight circuit. This is the first known use of a special MOS device to measure the internal environment of a space vehicle. Weight size and power demand are so low that the unit could be widely used as a 'housekeeping monitor' in future orbital pay-loads.
