Not having an Electronics background my questions may seem naive. However as the following issues give me concern I should very much appreciate it if they could be sorted out with some reliable knowledge. Firstly, do Liquid Crystal Display TV or computer monitors emit any ionizing radiation? I f the LCD screenbecomes damaged through the inadvertent use of the wrong typed of cleaner or by using any abrasive cloth could it expose one to increased ionizing radiation? Regarding the cold cathode fluorescent backlights of monitors I read in the Wikipedia encyclopedia under Cold Cathode that some ccfls use a source of beta radiation to start the ionization process. I f this is the case then could LCD televisions expose us to beta or gamma radiation. I should like to replace my CRT TV with a LCD TV, but the thought of a radioactive material being present causes me much anxiety.
