| Abstract | ||
| This work was carried out to study some the optical properties of polymer Carboxy methyl Cellulose (CMC) in the range of wave lengths (300 – 1100 nm) before and after exposure to gamma rays and two time periods 5 min and 15 min by using radiation source (CS137) at room temperature . We found where the absorbance and transmittance of the polymer and the calculation of Absorption and the Extinction coefficients and the optical energy gap of allowed and forbidden indirect electronic transition . The results showed a clear impact of the Gamma ray on the optical properties of the polymer (CMC)Where it was noted that the absorption coefficients lethargy values increased with increasing duration of irradiation While less optical energy gap values of allowed and forbidden indirect electronic transition with increasing the gamma ray doses | ||
