Diet
for coconut meat previously used 100 gm/d : best current est. 1300 gm/d
for coconut milk previously used 300 gm/d : best current est. 1500 gm/d
for breadfruit previously used 150 gm/d: best current est. 1350 gm/d
Reduce Table 12 (of Dose Assessment) by ~ x 10 (factor of 11.6 should
be 1.16)
Total dose reduction decreased by a factor of 3
Look at Am as class W rather than class Y compound
Look at Am ingrowth as factor of 2
Is it realistic to assume that 30 cm depth soil activities average
~ 1/2 of surface?
ratio of 30 cm/2 em ~ 55% - 65%
reasonable to use a factor of 2
Raises question of whether or not surface cleanup is adequate
k
Change:
concentration ratio; diet, Am ingrowth; Am class W instead
of Y; - revise dose assessment
result in low Pu doses; higher doses due to Cs/Sr
Items to be resolved this mtg for Hollister
Ray:
DNA now interprets advice to mean that clean-up of everything
> 400 pCi/gm is replaced by cleanup of everything > 160 pCi/gm
*
Assuming areas > 400 are guaranteed, what is land use classification if
*
What is an action level for subsurface removal?
Of depth, volume, extent, etc.?
—Is it a function?
*
What is the meaning of a Departmental sign-off?
levels are > 160 pCi/gm and < 400 pCi/gm?
