Staff recommendations were derived following
consideration of various options for reduction
of radiation dose below the criteria including
modification of the diet, plowing and removal
and replacement of layers of contaminated
soil. Associated ecological damage and soil]
disposal problems are unavoidable consequences
of large scale decontamination actions. The
Task Group did not view partial soil removal as
an effective and dependable method of reducing
radiation doses. Consideration of restrictions
on food production locations, although undesirable,
is absolutely necessary if radiation doses are tc
be reduced to acceptable levels.
DNA has recommended that a risk-benefit study
should serve as a basis for the decision on
dose criteria. The Task Group did consicer
estimates of risks associated with radiation
criteria derived from FRC guidance. Because
of many uncertainties associated with predictions
of effects of long-term low level doses from
