  1. For each reference the cell line, the radiation type, the ratios of the radiosensitivity parameters (if provided) under aerobic (a) and hypoxic (h) conditions and the OER behavior as a function of dose ( increases, decreases or → remains nearly constant with increasing single dose) are given. The low-LET range was chosen between 0.2 and 2 keV/μm.
