Method and apparatus for the detection of ionizing radiation

Creators

Description

A method and an apparatus for the detection of ionizing radiation is disclosed, in which a diamond is used as the radiosensitive element of the detecting apparatus, which diamond has low (2X10/sub -/3 at .% or less) nitrogen concentration and low (10/sub -/4 or less) birefringence, and in which diamond the lifetime of the free carriers generated by the ionizing radiation is 10-6s or longer. The current-voltage characteristic of the diamond under irradiation is linear at low bias voltage and the dose rate can be determined from the resistivity of the diamond. A synthetic diamond crystal can be used to advantage as the radiosensitive element
