When the physical working conditions are uncomfortable or inappropriate, the VDT operator must do something to adapt to the unsuitable conditions. The effort to cope with the environment is added to the already existing demands of the job, thereby increasing the level of stress. The organization of work involves the manner in which work is done. In addition to the actual design of VDT work, other job conditions can contribute to the stress of operators. These include low wages, absence of career advancement opportunities, and inadequate child care.
Many people fear that they are exposed to harmful doses of radiation when they use a computer.
The main concern regarding VDTs and radiation involves non-ionizing radiation emitted by VDTs. Nonionizing radiation is not as strong as x-rays and other types of radiation that are known to cause cancer and other illnesses. The source of the radiation is the flyback transformer located in the rear of the monitor. Therefore, the radiation is strongest at the back of the machine rather than in front of the screen. The research that has been conducted so far does not indicate that VDTs are a radiation hazard.
