or materials which show the number of fatal cancer
cases and the number of genetic malformations to
be expected from a dose of 170 millirem per
year, and the expected increase in the frequency
of such cancer cases and genetic malformations,
to be expected for the predicted dose rates
presented on page 8 of the attachment.
In other
words, what is the expected frequency of fatal
cancer cases
at an average dose rate for the
population of 170 millirem per year, compared with,
for the whole body, a dose rate of 210 millirem
per year, 240 millirem per year, and 260 millirem
per year?
For another example, what is the
expected increase in leukemia cases at 170 millirem
per year compared with 190 millirem per year,
260 millirem per year, 280 millirem per year,
and 300 millirem per year?
What is the expected frequency of genetic anomalies
at an average whole body dose rate of 5000 millirem
per 30 years compared with 2700 millirem,
millirem,
millirem?

4700 millirem,
3200
5200 millirem and 5700
Please provide any records, documents and materials
which would explain why the attachment and the
letter of May 15 did not contain any discussion
of the biological risks associated with .the
predicted doses.
If no such documents exist,
please so state, and explain why such a discussion
was not included in the advice provided to the
Department of Interior.
Thank you in advance for your prompt attention to this
request.
