| Abstract | ||
| In this research the effect of Gamma ray (T- ray) in some electric properties' of copper have been studied which were resistance (R (0)), current (I (A) & power (P (w)). For this research the tow kind of copper samples have been prepared, one sulTounded by insulator, and the other was not. Each one of tow kinds of copper samples have been divided in to (6) samples, (5) of them have been irradiated by gamma ray with doses (14,28, 42, 56,70( Gy)), and the last one of each kind of copper were left as control samples in ordered to compared with, contol samples mentioned to them in this research by (0 (GV)) dose. The changing in (R), (D, & (P) values with increasing of (y -ray) have been plotted as graphs. It was clearly observed that the resistance (R) were increased (compared with control samples) with first tow (y -ray) doses (14,28(Gy)), that increasing of (R) associated with increasing of current and power, but when the doses of (y -ray) have been increased to (42(Gy)) inverse case was happened were (R) value decreased with increasing of (I) &(P) in each kind of copper samples , increasing of (I) &(P) in this dose (az(Gy)) make the copper as super conductors in ordinary temperature , so this dose considered as an effective dose in this research . When (y -ray) doses have been increased to (56, 70( Gy)), (R) decreased to minimum values, with certainly increasing of (I) & (P) to maximum values. the abnormally decreasing of (R) &increasing of (I)&(P) proved of destroying atomic structure of copper ,that because of transform most of the electrons in copper (with effect of radiation) atoms to moving charges | ||
