The 289 area code was created as an area code overlay for the Mississauga (Streetsville) area. Unlike the previous solutions, this process did not require the place to be geographically separated by different area codes.
Ionizing radiation is a term used for radiation whose quanta have energy to directly or indirectly ionize (one or more electrons are released from the atom of the given substance) molecules or atoms while passing through matter, hence the name ionizing radiation.
Facts About Radiation. Radiation is energy that comes from a source and travels through space. When this energy passes into the body, either by penetrating skin or being swallowed or inhaled, it may be harmful. Whether the radiation is ionizing or non-ionizing will influence the health risks. Ionizing radiation Ionizing radiation is the high-energy radiation that causes most of the concerns about radiation exposure during military service. Ionizing radiation contains enough energy to remove an electron (ionize) from an atom or molecule and to damage DNA in cells.
