Paper Abstract

There has been widespread international concern expressed over the potential exposure of visual display unit (VDU) operators from radiations emitted by the VDUs. In order to investigate this potential exposure situation and to determine the extent of any such radiant energy exposure, a survey was organised to measure the radiation emitted in all regions of the electromagnetic spectrum from all VDUs currently available in the UK. With the exception of some special tests, all the surveys were carried out at manufacturers/suppliers' premises. In all, some 60 firms were visited and over 200 different models of VDU were surveyed using a common instrument/measurement protocol. All measurements were made with the detector either in contact with, or in close proximity to, the screen and all accessible sides of the casing. The brilliance and contrast controls of the VDU were adjusted to the maximum setting consistent with an acceptable display. The field survey measurements were made by National Radiological Protection Board staff acting on behalf of the Health and Safety Executive.
