from inhaled plutonium, the possibility remains that plowing
could increase the availability of 9°Sr and }37Cs to plant roots.
The Advisory Group will wait until comparative data are available
on the levels of
?9Sr and 137Cs in plowed and unplowed soil
before commenting further on plowing.
Dose assessments for
the two conditions would be especially useful if ?°Sr and 137Cs,
as well as the transuranics, were considered.
