The typical burden of
insoluble particles of respirable size (<« 5.0 Um
diameter)
is about one gram in human adults..- For
this reason I would recommend that surface soils

should not exceed about 1 pCi of
PuO, and other

insoluble alpha emitting particles per gram of
insoluble particulates of respirable size in the

the Colorado standard may give rise to excessive

the 40 pCi/g standard.

But
in the range between 40 and 400 pCi/g, the DEIS standards call for

Certain criteria are offered for guidance in the
exercise of this judgment, but they appear to be entirely too
unspecific and subjective.
