Recently a novel radiochromic sheet dosimeter, termed as PRESAGE sheets, consisting of leuco crystal violet dye and radical initiator had been developed and characterized. This study examines the dosimeter’s temporal stability and storage temperature dependence postirradiation, and its applicability for dose verification in three dimensions (3D) as a stack dosimeter.

用于三维剂量验证的堆叠式放射性变色片的温度依赖性和时间稳定性

最近，已经开发并表征了由无色结晶紫染料和自由基引发剂组成的新型放射性变色片剂量计，称为PRESAGE片。这项研究检查了剂量计在辐照后的时间稳定性和储存温度依赖性，以及其在作为堆栈剂量计的3维（3D）剂量验证中的适用性。
