  • Method of forming a film of novel composition for a dosimeter
    Patent number: 8691135
    Abstract: A tetrazolium bromide dye, e.g., 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), to be used as a high dose solution dosimeter is disclosed. The dose response of MTT solution dosimeter increases strongly with increase of absorbed dose up to 1 kGy. In order to increase the dose range and for ease of handling the present dosimeter as routine dosimeter, MTT-polyvinyl alcohol (PVA) film dosimeter is used. The dose response of MTT-PVA film dosimeters increases strongly with increase of absorbed dose up to 25 kGy. Polyvinyl butyral (PVB) as a polymer for making a film provides more stability at higher temperatures and humidity levels and less calibration is required. The dose response of MTT-PVB film dosimeters is effective with absorbed dose of up to 100 kGy.
