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.
It is known that X-Ray radiation is harmful. The effects of ionizing radiation can either be classified as stochastic (random) or deterministic (nonrandom). Through radiation protection, deterministic effects may be prevented and stochastic effects may be reduced.
