Cathode Ray Tube (CRT) monitors are associated with the possible emission of bremsstrahlung radiation produced by electrons striking the monitor screen Despite the widespread use of liquid crystal displays (LCDs), cathode ray tube (CRT) monitors are used extensively. They have advantages over LCD monitors, such as higher resolution, smaller motion artifacts, and higher color depth. In additional, due to the lower prices of CRT monitors, they are still widely used in some poor countries. Electromagnetic radiation in the non-ionizing range of the spectrum only has enough energy to be able to excite electrons to higher states and is insufficient to displace electrons from the atomic structure. Examples of non- ionizing radiation are visible light, infrared, radio waves, microwaves, and sunlight. Sitting in front of TV at a rate of 10 hours per day at close distances is exposed to dose higher than the permissible dose per year. The calculated doses are directly affected by time, so the longer the exposure time, the higher dose and vice versa. Also, reducing the distance between the source and the viewer leads to an increase in the absorbed dose and vice versa. It was observed that the readings of the right of the screen differ from the readings of the left of the screen, which is slightly higher, and this is due to the fact that the transducer inside the TV set is on the right side, as well as other parts that can generate X-rays. Therefore, it is preferable for the viewer to sit on the left of the screen as much as possible.
