Video display terminals
       The use of computers with screen-based output units or video display terminals (VDT) grows at an ever increasing rate. VDT operators have expressed concerns about possible effects from emissions of low-level radiation. Magnetic fields(frequency 15 - 125 kHz) as high as 0.69 A/m(0.9μT) have been measured close to the surface of the screen ( Bureau of Radiological Health, 1981) under worst-case conditions. This result has been confirmed by many surveys (Roy et al: 1984, Repacholi, 1985a ). In a comprehensive review of measurements and surveys of VDTs by National agencies and individual experts, it is concluded that there are no radiation emissions from VDTs that would have any consequences for health ( Repacholi, 1985a). There is no need to perform routine radiation measurements since, even if under worst-case condition, the emissions are well below any international or national standards.

     ＶＤＴ機器からの電磁波放射に関して気にしているユーザもいる。結論としては、国際的な、もしくは国家レベルの諸規格に比較して十分に低く、個々のＶＤＴ機器からの電磁波放射の測定の必要性もない。
