Abstract Cathode ray tubes (CRTs) emit electromagnetic fields of very weak intensity and are themselves particularly vulnerable to fields from other emission sources, as may be observed by distortions or flicker of the display. They are giving way to flat screens, which emit less radiation and are less sensitive to external radiation. This information sheet outlines the principles of operation of CRT displays and flat screens and sets out the levels of electromagnetic radiation emitted, the interference caused by nearby electromagnetic fields and measures to improve screen performance.
