Carol et al.,
It seems that there is a fundamental misunderstanding among many (most???) RADSAFErs. The dose after a nuclear contamination is only to a small percentage due to direct gamma-ray exposure, more important from inhalation, but overwhelmingly due to ingestion.
Gamma-ray Dose Constants will not help to determine the dose after a nuclear accident. Additionally the contribution from alpha- and beta emitters may play an important role, depending on the circumstances of the accident.
This is one of the lessons I learnt after the Chernobyl accident.
Do you have data on food contamination around Fukushima and the diet of people living there? I doubt.

Yes I do have data on whiole body monitoring after Chernobyl carried out by Nesterenko.
