INTRODUCTIONDosimetry plays an important function in the quality control of radiation processing (1) . Radiochromic ilms dosimeters based on the radiation-induced color bleaching of organic dyes have been extensively investigated for high radiation dose dosimetry (2)(3)(4)(5)(6)(7) and also in radiotherapy (8) . Clear polyvinyl chloride (PVC) ilms were investigated (9) , but there are only a few articles published about the use of PVC as a dosimeter for gamma radiation. Khan and Ahmad (10) reported that undyed PVC ilms with thickness of 1 mm were useful as gamma radiation dosimeters in the range of 1-30 kGy, and were stable for up to 30 days after irradiation. Radiation-induced color bleaching of PVC ilms containing malachite green and bromocresol purple dyes were investigated as high-dose radiation dosimeters in the dose ranges of 0-125 kGy (11) and from 0 to 50 kGy (12) , respectively. The effect of gamma radiation on the organic dye methyl red and its possible use in chemical dosimetry was investigated (13) . The useful dose range of aqueous solution of methyl red in alkaline was between 50 and 6000 Gy. Radiation-chromic ilm based on polyvinyl butyral (PVB) dyed with methyl red was investigated as a high dosimeter (14) in the range up to 150 kGy.The aim of this study was to use polyvinyl chloride PVC ilms dyed with methyl red as a high dose dosimeter. Since radio-chromic ilms used in routine dosimetry systems are usually in luenced by the environmental conditions such as irradiation time, dose rate, shelf life and post irradiation time, this study investigated the effect of these parameters on the dose range up to 150 kGy.

Dyed poly(vinyl alcohol) (PVA) films prepared by a simple technique of casting aqueous PVA solution incorporating a mixture of two dyes namely chlorophenol red (CPR) and Quinaldine Red (QR) on a horizontal glass plate are useful as high dose dosimeter in the dose range 2-30 kGy range. The colour of these films change from deep red to yellow when exposed to gamma radiation. Chloral hydrate was added with different concentrations. The response of the prepared films can be modified either by change of chloral hydrate concentration or ratio of the two dyes. As a result, these films can be used as a dosimeter in two dose ranges. The dosimetric parameters, e.g.; dose response, effect of relative humidity on response as well as pre-and post-irradiation stability of these films have been investigated.

Ferrotitanium alloy polymer films, prepared by a simple technique of casting aqueous solutions of poly(vinyl alcohol) PVA containing ferrotitanium alloy on a horizontal glass plate, are useful as routine high-dose dosimeters. These flexible plastic film dosimeters have pale yellow color, are bleached when exposed to gamma rays. The chemical composition of alloy was determined by EDX, and structure of alloy was determined by XRD. The response of these dosimeters depends on the concentration of alloy. The energy band gap E g was calculated and the effect of gamma radiation on its value was determined. The optical absorption spectra showed that the absorption mechanism is an indirect allowed transition which found that energy band gap E g decreases after irradiation. The response of these films has negligible humidity effects on the range of relative humidity from 0 to 100%. And also, it exhibits good pre-and post-irradiation stability in dark and light.
