Abstract:
1. A process, comprising: dissolving a tetrazolium bromide dye to make a solution; dissolving a polymer solution using a solvent; mixing the tetrazolium dye and the polymer solution to make a film for measuring an irradiation heating the solvent to 80° C. to dissolve the polymer to make the polymer solution; stirring the polymer solution using a magnetic stirrer for four hours; cooling the polymer solution to room temperature; adding the tetrazolium dye at a 1-5 mM concentration range to the polymer solution to make a mixture; stirring the mixture of polymer solution and tetrazolium bromide dye solution for 24 hours; pouring the mixture on a flat glass plate to form a uniform film layer of a specific thickness; drying the film till a constant weight for the film is obtained; cutting the film to a specific dimension for further use to measure irradiation; and storing the film in black plastic to protect from light, moisture and dust.
