摘要： A gel dosimeter for radiation dosimetry includes a radically polymerizable monomer, a gelator, glucose, and glucose oxidase. Although a conventional polymer gel dosimeter contains a deoxygenating agent such as tetrakis(hydroxymethyl)phosphonium chloride, such a deoxygenating agent fails to exhibit sufficient effects. Thus, a more effective deoxygenation treatment technique has been required for a gel dosimeter.
