Dear Dr. Bair:
Thank you for your letter of February 28, 1983.
I waited to fulfill your
request for a copy of the July 1983 abstract because it did not provide
information I felt you wanted. Enclosed is a copy of that abstract which
deals with both the protracted phase of dose equivalent and the acute thyroid
absorbed dose. I have also provided a recent letter from myself to Charles
Meinhold which presents updated estimates of thyroid dose which may be useful
to you.
The methods used in the thyroid absorbed dose assessment fit together
well and the absorbed dose values given in Table One of the letter to Charlie
make use of data from four different approaches. I am compiling the initial
draft and tabulating intermediate results, therefore, the data in Table One
are tentative. The range of thyroid dose is estimated to be about four times
the mean values.
Best regards.
Sincerely,
Edward TSesarrol.
