Abstract
The goal of this research was to measure extremely high doses of ionizing and non-ionizing radiation separately near a commercial nuclear reactor. Specially designed p-MOSFETs were used for detecting ionizing radiation. Custom PIN diode dosimeters were developed in-house for measuring high dose of non-ionizing radiation. The two semiconductor dosimeters successfully measured ionizing and non-ionizing radiation separately in a mixed-field high-radiation environment. The neutron sensitivity of the developed dosimeter was 14.63 mV/cGy, or three times higher than that of the conventional ones. This paper describes the development, calibration, and application of the diode dosimeter.
