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.
BIOLOGICAL EFFECTS OF IONIZING RADIATION. Ionizing radiation in very high levels is known to increase the incidence of cancer, birth. anomalies, erythema, and other problems. In low levels, these effects are either very, very small. compared to natural incidences or non-existent depending on the biological model used for. estimating the potential risk.
