2, Calculation of cumulative dose rates and dosages
from external radiation and internal radiation
of various kinds and under various conditions
of exposure
N, Philosophy:
the assumptions and models behind the
establishment of the standards
aa
1. Historical trends to the present and trends for
the future
2. The validity of the assumptions now used in the
light of up-to-date knowledge
3.° Possibility of hazards resulting from low-level
exposure:
threshold
considerations
a. Why do we not know whether or not there
is a-threshold for each of the various
radiation effects of interest?
How and
when can we improve knowledge on this
point?
b. A radiologist may believe that the existence of a threshold is probable or he
may not...what are the pros and cons?
ec, What about the acceptability of the currently
recommended standards under either belief
of (b)?
a
4, The probable trend of the standards for the
future
a. Will new standards have to be developed to
cover certain hazards not now adequately
protected against?
b,. Are the standards defined in such a way
that they can be ranked for any given
situation so that the proper standard
among several can be chosen to give the
least likelihood of hazardous exposure?
Is
there any ambiguity if several standards
apply?
c. Do there now exist, or are ther likely
to be, different standards in use by the
U. S. and other governments,
or by the
U. 5S. and states and municipalities?
