This is followed in Section III by a review of the
specific radiation protection regulations that are in force
in the United States today and which are at issue.
This
section focuses on the existing guidelines for Pu-239, but it
is to be understood that,
in this
and subsequent sections,
it should be applied to all alpha-emitting radionuclides that
meet the hot particle criteria developed in this report.
Before readins Section III,
those unfamiliar with
the
national ana international organizations which have primary
responsibility Zor recommending or establishing radiation
protection standards, may find it useful to read Appendix
&, where these organizations and their authority are reviewed.
:
Section IV presents assumptions inherent in the existing
Pr
inappropriate when applied to insoluble
articulates.

radiation protection standards and identifies those assump-
The biological data which
demonstrate that these assumptions are inaporopriate when apvoglied
to hot carticles are discussed in Section Vv.
Uvilizing the data presented in Section V,
the
criteria that define a hot particle are developed in Section
YI.
Recommendations for exposure standards
for hot particles
are then develoced in Section VII and summarized in
Saction VIII.
