Charge Distribution and Thermally Released Current in the Gamma-Irradiated Cerium-Glass
Tokyo Metropolitan Isotope Research Center
(Received March 8, 1971)
The thermally released current of the cerium-glass irradiated with 60Co-γ-rays is measured under the condition of temperature-gradient through the glass and no external applied electric field. This current has considerable differences due to the condition whether directions of radiation and temperature-gradient are parallel or antiparallel. When a copper plate 0.3 mm in thickness is placed in front of or at the back of glass specimens during irradiation, this current in specimen at the hot or cold side changes. These current carriers are Compton electrons generated in the specimen and secondary electrons injected into the specimen from surroundings. The relationships of the thermally released current and the charge distribution produced by γ-rays are discussed.
