The term radiation is a broad term that covers a large number of wave energies (the electromagnetic spectrum) to which we may be exposed. On one end of the energy spectrum is ionizing radiation, i.e., x rays. On the other end is nonionizing radiation. Computers emit nonionizing radiation.here is no measurable ionizing radiation (x rays) emitted from a computer monitor. The nonionizing radiation or electromagnetic radiation that may be emitted does not represent a reproductive risk either. There are many studies showing that birth defects or miscarriage is not associated with working at a computer.
