In considering the reduction in exposure that may be achievable through
removal of contaminated soil, the Task Group has taken the position that these
predicted exposures are approximations only. The effectiveness of such actions

Taeaansanomant of dose reductions that might be possible due to
removal of contaminated soil, the Task Group posed the following questions:
“Given the dose estimates of ables

-4, and the dose reductions that can

be achieved by removal of soil and, if so, what volume of soil would have to
