我们于1989年11月～1900年11月对盟旗两级医疗防护单位的紫外线消毒质量进行了监测。结果紫外线强度总合格率为60.94%(39/64)。照射消毒后空气中细菌总数平均3257个/m~3,超出国家标准的6.51倍。分析其原因主要是(1)紫外线强度低,达25～40μw/cm~2 者占51.35%;(2)室内湿度大,相对湿度≥80%
From November 1989 to November 1900, we monitored the UV disinfection quality of the Union level two-level medical protection units. Results The total qualified rate of UV intensity was 60.94% (39/64). The average number of bacteria in the air after disinfection was 3257 / m ~ 3, 6.51 times higher than the national standard. Analysis of the main reasons (1) low UV intensity, up to 25 ~ 40μw / cm ~ 2 accounted for 51.35%; (2) indoor humidity, relative humidity ≥ 80%
