As seen from Table IV, using Geesaman's lung model, a
particle with an alpha activity between 0.02 pCi and 0.14
pCi
is recuirai to give a dose of 1000 rem/yr to irradiated lung
tissue.
For purposes of establishing a maximum permissible
lung particie burden we will use 0.07 pCi
lived
(greater than one year)
from long haltf-
isotopes as the limiting
aloha activity to qualizy as a hot particle.
Thus, throughout
the remaincer of this resort, hot particle will imply a particle
with at least this limitins aloha activity which is insoluble
