Abstract
The electronic absorption spectra of dithizone (H(2)DZ) and its metal complexes of Hand Cd and Zn doped in poly(methylmethacrylate) PMMA has been investigated before and after gamma-irradiation. It is found tha t the complex formation resulted in significant changes in both the po sition and the intensity of the electronic bands of H(2)DZ. Gamma radi ation causes remarkable decreases in the intensities of most of the ab sorption bands of the metal complexes. The rate of decrease depends on the nature of the metal ions.
