Calculation of cumulative dose rates and dosages from
external radiation and internal radiation of various kinds

Philosophy: the assumptions and models behind the establishment
or the standards
1.
Historical trends to the present and trends for the future
2.
The validity of the assumptions now used in tke light of
up-to-date knowledge
3.
Possibility of hazards resulting from low-level exposure:
threshhold considerations
a.
Why do we not know whether or not there is a threshhold for each of the various radiation effects of
interest?
this point?
4.
How and when can we improve knowledge on
b,
A radiologist may believe that the existence of a
threshhold is probable or he may not...what are the
pros and cons?
c,
What about the acceptability of the currently recom--
mended standards under either belief of (b)?
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 there likely to be,
‘
different standards in use by the U. S. and other
governments, or by the U. S. and states and munici-
palities?
