	<span style=\"font-size:12px;font-family:Verdana;\">In this study the spectrophotometric response of the Toluidine Blue O
(TBO)-gelatin gel dosimeter irradiated with gamma rays was characterized.
Preparation of dyed-gelatin gel takes place in neutral medium; to give
eventually gel dosimeter has a sharp absorbance peak at 635 nm that bleaches
quantitatively upon irradiation and the colour change can be measured with
UV-VIS spectrophotometer. The useful dose range was 1 - 150 Gy. The radiation
chemical yield (G-value) of gel dosimeter was calculated and found to increase by
increasing concentration of dye. Post-irradiation storage on the response of
gel is discussed. The dose response function, radiation sensitivity, and
dependences of the response on environmental factors were studied.</span>
