The analysis for dosimetry is made with spectrophotometric measurements (at visible light wavelengths) of pre-irradiation absorbance, <em>A</em><sub>0</sub>, and radiation-induced absorbance, <em>A</em><sub>i</sub>. Either the wavelength of the maximum of the absorption band that bleaches upon irradiation (<em>γ</em> = 425 <em>nm</em>) or the wavelengths of the maxima of the two overlapping radiation-induced absorption bands (<em>γ</em> = 525 or 556 nm) are used to make these measurements. The most reproducible calibration consists of the ratio, <span><math><mtext>A</mtext><msub><mi></mi><mn><mtext>i</mtext></mn></msub><mtext>A</mtext><msub><mi></mi><mn>0</mn></msub></math></span>, at a given wavelength, as a function of the absorbed dose. The new film dosimeter is flexible, rugged, and relatively stable at temperatures between −80°C and +50°C, and in daylight. The radiation-induced color, in terms of the absorbance, <em>A</em><sub>i</sub>, at selected wavelengths, is unstable for about two days subsequent to irradiation, after which the values of <span><math><mtext>A</mtext><msub><mi></mi><mn><mtext>i</mtext></mn></msub><mtext>A</mtext><msub><mi></mi><mn>0</mn></msub></math></span> remain stable for at least several months, even under illumination with white fluorescent or indirect daylight. The film color is unstable at high temperatures (60°C and above). The film sensitivity to gamma radiation increases gradually with rise in irradiation temperature up to 50°C and then decreases sharply at temperatures above 60°C. There is only slight variation of response with change in relative humidity during irradiation.</p></div>","PeriodicalId":14288,"journal":{"name":"International Journal of Radiation Applications and Instrumentation.
