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.
Radiation is the transfer of energy by electromagnetic wave motion. Once the Sunâs energy reaches Earth, it is intercepted first by the atmosphere. A small part of the Sunâs energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the Sunâs energy is reflected back to space by clouds and Earthâs surface. Most of the radiation, however, is absorbed by Earthâs surface. When the radiation is absorbed by a substance, the atoms in the substance move faster and the substance becomes warm to the touch.
