Radiation-induced lung injury is a general term for damage to the lungs which occurs as a result of exposure to ionizing radiation.[1] In general terms, such damage is divided into early inflammatory damage (radiation pneumonitis) and later complications of chronic scarring (radiation fibrosis). Pulmonary radiation injury most commonly occurs as a result of radiation therapy administered to treat cancer.[citation needed]

Symptoms and signs[edit]

The lungs are a radiosensitive organ, and radiation pneumonitis can occur leading to pulmonary insufficiency and death (100% after exposure to 50 gray of radiation), in a few months. Radiation pneumonitis is characterized by:

Symptoms of radiation pneumonitis include: fever, cough, chest congestion, shortness of breath, chest pain
