Lung chip model offers new insights into how radiation damages the lungs

The lung is one of the tissues most sensitive to radiation in the human body. People exposed to high radiation doses following nuclear incidents develop radiation-induced lung injury (RILI), which affects the function of many cell types in the lung, causing acute and sustained inflammation, and in the longer term, the thickening and scarring of lung tissue known as fibrosis.
