Incertitude about models …
In the range of weak doses (below 200 mSv), the relationship between dose and effect is left to the inspiration of the individual scientist. The absence of reliable data makes accurate prediction difficult and so a range of alternatives to the ICRP model are also available. Two popular alternatives are a linear relationship with a lower bound below which radiation produces no effect, or a low-dose region where an effect known as ‘hormesis’ means that low doses might conceivably have beneficial medical effects.
