They can also come from microwaves used to heat food. There are 2 types: This fact sheet focuses on the ionizing type.

  • Radiation Pneumonitis

    Radiation pneumonitis is an inflammation of the lung tissue. Radiation pneumonitis often appears between 6 and 24 weeks after radiation therapy. Air moves through the airways into air sacs of the lungs called alveoli. The alveoli have several blood vessels that allow for gas exchange between the lungs and blood. Oxygen can pass from the lungs to the blood and carbon dioxide can pass from the blood to the lungs. Radiation pneumonitis causes inflammation in these alveoli. The inflammation can decrease the amount of oxygen that enters your body. If it remains untreated, pneumonitis can also lead to permanent tissue damage.
