Keep the television as far away from viewers as the room will allow. Remember that the backs and sides of TV sets and PC monitors are even more dangerous than the screen. Limit your exposure as best you can, and be strict with children who want to sit close, as they are in even more danger than adults. There are devices for computers that offer protection, and there are screens that can be installed in front which cut radiation. Liquid Crystal Display (LCD) and Thin Film Technology (TFT) computer screens are said to be radiation-free, and plasma and back-projection television screens are safe.
