Abstract
In this study, two types of normoxic N-vinylpyrrolidone based polymer gel, VIPET1v and VIPET2v, were presented. VIPET2v had the double amount of monomer compared to the VIPET1v. The influence of this difference in the dosimetric characteristics of the polymer gel dosimeters was investigated. The doubling in N-vinylpyrrolidone concentration increased the dose sensitivity in the linear dose range region and improved the dose resolution at 95% confidence level for lower doses (D<10Gy). Unfortunately, this increase in concentration reduced the dose range response. VIPET1v was sensitive in the dose range of 2 to 60 Gy, while VIPET2v was sensitive in the dose range of 1 to 30 Gy. Moreover, both gels showed a linear R2-dose response for one month post-irradiation time period. During this time, variations in dose sensitivity and offset values of both dosimeters were observed. Finally, the dose resolution temporal stability was studied and was eventually improved by doubling the N-vinylpyrrolidone concentration.
