电子计算机的出现,极大地提高了生产和工作的效率。特别是微型机的开发应用使各种生产和工作场所迅速改变了原来的面貌。近十年来大量微机进入办公室甚至许多家庭,使一些发达国家的社会也发生着深刻的变化。据估计,现在美国各工作场所拥有的视屏显示终端(Video displayterminals,简称VDTs)总数已达1500万—1900万台,到本世纪末将拥有4000万台。近年来国内许多工作场所对VDTs的使用也日趋增多。随着这一新技术的出现和普遍使用也带来了新的问题,那就是VDTs作业是否对健康有危害,这种担心越来越普遍。目前在美国人们对VDTs作业比较担心的有可能涉及的健康问题主要集中在三个方面。 1.VDTs是否有辐射的危害,2.VDTs是否会
The advent of electronic computers has greatly increased the efficiency of production and work. In particular, the development and application of microcomputers has rapidly transformed the various aspects of production and the workplace. During the past decade, a large number of computers have entered the office or even many families, and profound changes have taken place in the society of some developed countries. It is estimated that the total number of Video Display Terminals (VDTs) owned by various workplaces in the United States now stands at 15 million to 19 million and will reach 40 million by the end of this century. In recent years, the use of VDTs in many workplaces in China has also been increasing. With the emergence and widespread use of this new technology, new concerns have arisen as to whether the VDTs’ work is hazardous to health. At present, there are three main health problems that may be involved in the concern of the U.S. people about VDTs. 1. Is there any radiation damage to the VDTs, 2. Will the VDTs
