CRT TVs have a bad impact on our surroundings
A CRT TV has a vacuum tube and an electron gun which emits electrons when heated and this will get focused on beam. These are deflected back using the magnetic field on the front display, which glows and hence forms the desired image on the screen
Simple, isn’t it? Not quite.
This above stuff happens inside the TV, electromagnetic fields are generated from inside. Exposure to these fields is very hazardous in the long run, as these fields affect the functioning of living cells and these Very Low-Frequency Emissions (the fields)causes, disturbance in the growth of bones, irregularities in the heart rate and even alterations in the genetic structure!
To avoid all this havoc, one needs to sit at least 90cm away from the CRTs which produces radiations, thus they obey the inverse square law and weaken over the increase in distance.
