WebThe oxygen enhancement ratio ( OER) is almost in unity for Bragg peak helium ions, whereas x-rays need to deliver about 2.5 times more dose for the same cell survival and tumor response under hypoxic conditions at the 10% survival level. Modified from Raju MR (1980) Heavy Particle Radiotherapy. London: Academic Press. Oxygen cycle refers to the movement of oxygen through the atmosphere (air), biosphere (plants and animals) and the lithosphere (the Earth’s crust). The oxygen cycle demonstrates how free oxygen is made available in each of these regions, as well as how it is used. The oxygen cycle is the biogeochemical cycle of oxygen atoms between different oxidation states in ions, oxides, and molecules
