摘　　要：目的了解武汉地区家居装饰装修后室内环境卫生状况。方法对241套普通新装修住宅进行检测,监测项目为居室γ辐射水平、室内空气中甲醛、氡、苯。结果检测241户新装修住宅γ辐射水平样品1 098份、空气中氡241份、苯41份,合格率均为100%;空气中甲醛共测定样品816份,合格率为34%。结论新装修居室甲醛污染状况不容忽视,应加强室内通风换气以及栽养花卉降低室内甲醛污染对人体健康的危害。Objective To know the environment situation in the indoor air in newly decorated rooms in Wuhan region. Methods 3 - Methyl -2 - benzothiazoline hydrazone hydrochloride （MBTH） spectrophotometric method was used to determine the concentration of formaldehyde in the indoor air in 241 newly decorated fiats. Twinkling radiometer was used to cletermine the radiation level of γ in the indoor air. Emanometer was used to determine radon in the indoor air. The equipment for detecting VOC was used to determine benzne in the indoor air. Results 1 098 samples of the radiation level of γ and 241 samples of radon and 41 samples of benzne in the indoor air in 241 newly decorated fiats were determined, and the qualified rate was 100%. 816 samples of formaldehyde were determined ,and the qualified rate was 34%. Conclusion The indoor air pollution by formaldehyde in newly decorated rooms is severe. Ventilation should be strengthened in newly decorated fiats. The harm to health caused by formaldehyde can be reduced by flowering plants.
