Effects of Gamma Irradiation on Dosimetry Characteristic of Rhizophora apiculata Dye Solution

Abstract

The dosimetry characteristic of Rhizophora Apiculata dye solutions with and without 2, 3, 5 - triphenyltetrazolium chloride (TTC) salt to low dose of gamma irradiation up to 100Gy were investigated spectrometrically. The maximum absorbance was peaking at wavelength of 664nm characteristics of red colour. The dose responses at 664nm wavelength were found decreased with increase of gamma irradiation leading to colour bleaching of the dye solution. The dose sensitivity value of dye solution with TTC lower compared to dye solution without TTC. The colour stability of dyes solutions also have been investigated, the absorbance spectra found no significant change after stored in a dark room at room temperature for 2 weeks.
