摘要：

A new thin film dosimeter has been developed by using a chlorine-containing polymer matrix doped with malachite green methoxide as an indicator. Gamma irradiation of the film induces blue characteristic colour. The produced film with an average thickness of 0.05 mm has a linear response over the dose range of 1-60 kGy at the measured wavelength of 630 nm. The effects of temperature and relative humidity on the film response have been studied. The maximum absorbance of the film is found to be relatively stable over storage period of four weeks.
