Dear Tom:
I have just returned from the Seven Year Follow-Up
Study of the Rongelap people and was pleased that things
went very well indeed.
I found your letter on my return
with several queries with regard to these studies.
In re gard to the web.c.'s, we have not yet analyzed the data but
it appears as though the white counts are still on the low
Side this year. I am not sure whether the control counts
will be low; the explanation for this is not apparent at this
time,
You referred to the history of nausea and vomiting the
first two days after exposure.
Careful reviews of the case
histories during this time did reveal that the people on
Rongelap Island had extensive anorexia ana nausea during this
period ana some few vomited. This seemed to be a true state
of affairs and did not seem to be based on emotional disturbance when viewed in the light of the fact that people on
Ailingnae, Rongerik, and Uterik did not complain of these
symptoms.
So it would seem that doses around 150 to 175 r
represent the threshold for these complaints,
I greatly appreciate your continuing interest in these
studies Tom, and should you have any ideas or suggestions in
regard to this work it would be greatly appreciated,
Sincerely yours,
RAC sag
