Does the dose rate of an external beam linear accelerator matter in terms of radiobiology?
There is increasing technology available (ie flattening filter-free beams) to substantially increase dose rate.
Answer from: Radiation Oncologist at Community Practice
Per Hall, "The dose-rate effect caused by repair of sublethal damage is most dramatic between 0.01 and 1 Gy/min; [a]bove and below this dose-rate range, the [cell] survival curve changes little, if at all, with dose rate." "Old" linacs could pump out about 6 Gy/min; new ones, up to 24 Gy/min. Sublet...
