The former hypothesis is mainly based on mathematical linear extrapolation from effects observed by high doses. This notion advocates the linear assumption of radiation risk and that there is no lower limit to the amount of radiation that causes short- or long-term damage. The latter is the countervailing hypothesis-radiation hormesis.
