Even if LNT would under-predict it is still a rounding error in the big picture of the tsunami disaster.
And, let's put it straight: LNT is scaremongering fiction. People who live in Ramsay, Iran, are exposed to higher level of background radiation that n what is allowed for nuclear workers. Yet, there is no elevated levels of cancer or birth defects, not is there a shorter lifespan for people living there either.
The dose makes the poison: https://en.wikipedia.org/wiki/The_dose_makes_the_poison
Epidemiology is a very blunt instrument. The data you mention there cannot be used to reach the conclusion you are trying to reach, since confounding effects cannot be excluded (and because the doses they receive can only be estimated, not actually measured). Yes, radiation biologists know all about those people and have judged that evidence as part of a larger picture.
