X-ray Hazard from Colour Television Sets and Video Display Terminals


Measurement and assessment of dangerosity of X- ray leakage from coloured television (TV) and video display terminals (VDT) are attempted. Three different techniques have been used (X-ray film, scintillation counter and Geiger counter). A comparison of the X-ray film result with literature value is made. Another comparison of the three techniques with published values is also made.Although big differences are noticed between most of the readings cited in the literature and those found in the present work, it can be seen that all reading are less than the maximum limit of the natural background radiation dose (2 m Sv/y).
