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.
Late Effects of Radiation Therapy. Radiation therapy is applied to the areas of the body that are affected by cancer. Aftereffects occur only in the area that was treated. In some cases, treatment may also include healthy tissue. This is to make certain that all of the cancer is treated. Newer methods of radiation therapy help minimize damage to normal tissue. Treatment is directed to the same area each time. Yet, radiation rays sometimes scatter. Tissues and organs near the cancer site might receive small doses of radiation if this happens. Late effects of radiation could include: Cataracts. Fatigue. Dry mouth. Permanent hair loss. Problems with thyroid or adrenal glands.
