When there is no statistically significant increase in cancer with increase
in dose, the problem may be weak statistical power rather than the
invalidity of LNT. I cannot tell from this abstract whether any LNT model
was actually tested  or whether the data are robust enough to allow such a
test.

The point here is that the absence of a statistically significant effect
does not invalidate LNT unless there is a statistically significant
difference between the LNT predictions and the observations.
