The conclusions are to all intents and purposes identical
to those of the National Academy off Sciences report,
1, Adequate justification should be required for the
employment of any source of tonizing radiation on however
small a scale,
This is not explicitly stated in the
National Academy of Sciences report but is inherent in i#,
2,Dose lévels to the individual - 0,3r per week ~ 200p

This is a rather roundabout way of saying,
‘let's be careful,"
5, a, All sources of radiation should be under close
inspection,
A personal record not only of doses of
radiation received during occupation but also of
exposure from all other sources such as medical
diagnostic radiology should be kept for e11 persens
yhose occupation exposes them to additional sources
of radiation,
The National Academy of Sciences report
would seem to include the whole population in its
similar recommendations,

b. Present practices in metical diagnostic radiology
should be reviewed with the c ject of clarifying the
indications for different special types of exemination
