The relative ineffectiveness of radiation at low dose-rates is generally regarded as resulting from ... HORNSEY, S., ALPER, T. Unexpected Dose-rate Effect in the Killing of Mice by Radiation ...

The estimated association of radiation dose with solid cancer was smaller, larger, and similar in magnitude, with five-, 15, and 20-year lags, respectively, relative to the 10-year lag assumption.

The UChicago researchers therefore dubbed the new, opposite response the "badscopal effect," as a play on words for when unrelated metastatic tumors grow after radiation.
