六十年代兴起的激光技术,至今已为工业、农业、医学、遗传学和国防上广泛应用,因此接触激光的工作人员将越来越多,对研制和应用激光的工作人员的机体健康状况是否存在着影响的问题已引起了人们的关注。从研制和应用激光的过程中所造成的微环境改变而间接地作用于工作人员机体的研究国内外已有报道。广州医学院等在对广州地区激光工作者健康普查中曾作染色体畸变观察,我们也对其中的40名激光工作者(包括研制和应用)作了外周血淋巴细胞姐妹染色单体互换率的观察,欲 Since the rise of the laser technology in the 1960s, it has been widely used in industry, agriculture, medicine, genetics and national defense. Therefore, there will be more and more workers exposed to laser light, and will the health of the staff who develop and apply laser be The problems that have an impact have drawn people’s attention. From the development and application of laser process caused by changes in the micro-environment and indirectly act on the body of the staff has been reported at home and abroad. Guangzhou Medical College and other workers in Guangzhou during the health survey of chromosome aberrations have been observed, and we also 40 of the laser workers (including the development and application) made peripheral blood lymphocytes sister chromatid exchange rate Observation, desire
