Abstract

This paper presents the detailed studies of the current-voltage (I-V) characteristics of a compressing thick disc pellet of lead nanoparticles which it is exposed to gamma radiation. The I-V characteristics are carried out for the pellet as exposed to a disc–type ⁶⁰CO radiation source with an activity of 370KBq.The data analyzed to obtain current versus dose plots at different applied voltages. These plots are clearly showing that, the induced current increases quite linearly versus radiation dose. The interaction of the gamma rays with the Pb nano matter can produce charge-hole pairs leading to the generation of electronic current. Nevertheless the nano lead enhances sensitivity to gamma-radiation, it may be used to improve and develop units and devices for radiation detection for environmental safety and effectiveness of nuclear power engineering.
