It was earlier thought that the radiation emission from VDT causes health effects to the user. Ionizing radiation is known to cause human cellular changes and break down the chemical bonding and change the neutral molecules. But VDTs do not produce or emit alpha, beta or gamma rays or hard x-radiation. Small amounts of soft x-rays are produced. But it is also contained by the monitors’ glass screen. Studies have shown that there is no evidence to support that VDT operators face
Hazards like skin cancers, spontaneous abortions and ocular abnormalities due to ionizing radiation. Research should be done to define the risk of electromagnetic radiation produced by VDT.
