Radiation risk assessment have been modernized less than DARE propaganda.

The Linear No-Threshold LNT hypothesis/model is still the fundament of all radiation protection theory and the modeling used in it.

The problem with using that is that since twenty years back we've known that both antioxidant activity and DNA-repair and protection mechanisms do not scale linearly.

Meaning that a more correct approximation of reality would be using a Non-Linear With-Threshold model.

But because our culture of permanent radiation hysteria we're paralyzed when it comes to changing the overarching guidelines, even when everyday practice have practically left it behind.
