描述了一种UVB特定剂量计,其包括:分散在聚合物(羟乙基纤维素,HEC)膜中的氧化还原染料(2,6-二氯靛酚,DCIP)、半导体(氧化锡(IV),SnO 2)和牺牲电子供体(甘油)。在没有UVB光的情况下,剂量计呈蓝色,但在暴露于UVB光时迅速失去颜色。详细介绍了典型UVB剂量计胶片的光谱特性和颜色变化的机理。DCIP UVB剂量计薄膜表现出与UVB暴露的辐照度水平和持续时间、存在的SnO 2水平以及在较小程度上存在的甘油水平相关的响应。剂量计的响应似乎是独立的染料浓度和膜厚度。此外,DCIP UVB剂量计薄膜对太阳模拟光作出响应,表现出颜色损失,这可以简单地与II型皮肤的最小红斑剂量(MED)暴露有关。因此,这些指标有可能用于测量太阳辐射照射,并为大多数高加索人皮肤(即II型皮肤)提供红斑预警。
A UVB specific dosimeter is described comprising: a redox dye (2,6-dichloroindophenol, DCIP), a semiconductor (tin(IV) oxide, SnO2) and a sacrificial electron donor (glycerol) dispersed in a polymer (hydroxy ethyl cellulose, HEC) film. The dosimeter is blue in the absence of UVB light but rapidly loses colour on exposure to UVB light. The spectral characteristics of a typical UVB dosimeter film and the mechanism by which the colour change occurs are detailed. DCIP UVB dosimeter films exhibit a response that is related to the irradiance level and duration of UVB exposure, the level of SnO2 present and to a lesser extent the level of glycerol present. The response of the dosimeter appears to be independent of dye concentration and film thickness. Furthermore, DCIP UVB dosimeter films respond to solar simulated light, exhibiting a colour loss that can be simply related to the Minimal Erythemal Dose (MED) exposure for skin type II. As a consequence, such indicators have potential for measuring solar radiation exposure and providing an early warning of erythema for most Caucasian skin (i.e. skin type II).
