I am, and I'm sure that most of our colleagues are aware of that. As it
turns-out, there are rules for such things in the Contaminated Territories.
1) Don't eat the berries; 2) Don't drink the milk; and 3) Don't eat the
mushrooms. These three items reduces internal dose by over 90% according to
my colleagues at Sosny Labs near Minsk.
My study in the San Luis Valley includes internal dose as well as external.

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.
