摘要
由于新冠疫情,手持式UV-LED消毒器广泛进入了市场。为了对这类消毒器的有效性进行分析,应用KI/KIO化学曝光剂对手持式紫外线消毒器的辐射场进行了测量。结果显示,手持时间30 s是可舒适使用的时间上限。紫外线的波长、辐射照度影响消毒的效果;消毒器上灯珠的几何分布及照射距离影响有效消毒面积。在一定范围内往复移动消毒器可以扩大消毒面积,但牺牲了局部的照射时间。
Due to COVID-19, handheld UV-LED disinfectors have largely been on market. To assess the effectiveness of such disinfectors, we used KI/KIOchemical actinometer to measure the radiation field of a disinfector. The results indicate that 30 seconds of holding is the upper limit of time for users to feel comfortable;ultraviolet wavelengths and irradiances influence disinfection effectiveness;the geometric distribution of UV-LEDs of the disinfector and the distance between the disinfector and the disinfected area influence the area of effective disinfection. It may expand the disinfection area to move a disinfector back and forth, but the radiation time of local areas is sacrificed.
