1-is it true that electromagnetic radiation , from computers n mobile phones are bad for you, ? 2-is it true that computers emit ozone which is toxic

Ozone: I use ozone daily in my office. High voltage can make ozone. Lungs and eyes are less tolerant of ozone than other tissues. Do u smell it? However it may be improving your health. Ozone is used in europe subways and schools to reduce bacteria and virus in air. Ozone is very reactive and does not last long in air. I believe that if the amount was high enough to cause you harm you'd know it.
