Oxygen enhancement ratio

ID: oxygen-enhancement-ratio

The Oxygen Enhancement Ratio (OER) is a concept used in radiation biology to describe the increased effectiveness of ionizing radiation in killing cells under conditions of higher oxygen concentration compared to hypoxic (low oxygen) conditions. In general, the presence of oxygen enhances the effects of radiation on tissues because oxygen can facilitate the formation of free radicals and other reactive species, which can lead to increased damage to DNA and other cellular structures.
