Abstract
Thermoelectric currents have been observed in thin lucite disks after exposure to γ radiation. If an electric potential difference is also impressed upon the sample during the heating cycle, the currents are enhanced or depressed depending on the magnitude and polarity of the applied voltage. The measured charge is a linear function of the applied electric field strength and the field strength necessary to completely suppress the currents appears to be more closely related to the radiation dose than to the temperature gradient in the sample during heating.
