摘要: 目的 评价一种上层空间紫外线杀菌系统的照射效能。 方法 在装有“思诺恒时TM室内空气杀菌系统”的模拟病房或诊室里,用紫外线辐射强度测量仪在杀菌系统正前方1.0 m处及左右各0.5、1.0、1.5 m及对面墙壁4.8 m处,以及上述每个点的上下5 cm和10 cm处测量紫外线辐射强度,并在约1.7 m的人面部高度测量该系统的辐射强度和剂量。紫外线照射强度>10 μW/cm2为有效杀菌强度;辐射剂量<0.2 μW/cm2为安全剂量。 结果 距离“思诺恒时TM室内空气杀菌系统”正前方1.0 m处的辐射强度为427 μW/cm2,其左右两侧(1.5 m)接近墙壁的位置辐射强度分别56 μW/cm2和58 μW/cm2,在正前方1.5、2.0 m和对面墙体即4.8 m处的辐射强度分别为179 μW/cm2、111 μW/cm2和70 μW/cm2结论 上层空间紫外线杀菌系统是一种安全、高效的消毒工具,适用于呼吸系统传染病,特别是结核病感染控制。

Abstract: Objective  To evaluate the radiation efficiency of a kind of ultraviolet germicidal irradiation (UVGI) system at upper room.  Methods  In an simulation ward and clinic equipped with “SINOVOTM constant indoor air sterilization system”, to measure the radiation intensity in the following points: 1.0 m ahead of the system, 0.5 m, 1.0 m, 1.5 m to the left and right side of the system, 4.8 m of the opposite wall, and upper and lower 5 cm and 10 cm of each points mentioned above, and also the facial radiation strength and dose of 1.7 m height people. The intensity over 10 μW/cm2 is effective germicidal strength, and radiation doses of less than 0.2 μW/cm2 is safe dose.  Results  The radiation intensity is 427 μW/cm2 1.0 m distance ahead of “SINOVOTM constant indoor air sterilization system”, 56 μW/cm2 and 58 μW/cm2 in its left and right sides (1.5 m) close to the walls,179 μW/cm2, 111 μW/cm2 and 70 μW/cm2 1.5 m, 2.0 m ahead and 4.8 m at the opposite wall.  Conclusion Upper room UVGI system is a safe, efficient disinfection tool which could apply to infection control of respiratory infectious diseases, especially for tuberculosis.
