Linear no-threshold and ALARA are pretty objectively overly conservative, to the point of potentially doing more harm than good (Fukushima is mentioned down below. More people died as a result of the evacuation than would have resulted from the radiation) as well as making many things obscenely expensive. It's a little absurd that nuclear plants obsess over radiation doses smaller than a short-haul flight.

Linear no-threshold being false doesn't necessarily mean a little bit of radiation is good for you, though there is some shaky data to suggest that might be true, just that small amounts of radiation are not as proportionally bad as large amounts.
