Radiology staff constantly exposed to ionizing radiation was evaluated to determine the relationship between pulmonary function and blood parameters. Although the respiratory functions of radiology staff are affected by many factors, continuous exposure to ionizing radiation is one of the important parameters. Radiology staff should be informed about preventable factors that negatively affect respiratory functions.

The explosive hydrogen gas could selectively reduce hydroxyl which plays an important role in irradiation-induced injury. Hydrogen-rich solution may be a novel, safe and effective radioprotector.
