RADIATION STANDARDS, INCLUDING FALLOUT
Senator Anperson. This isnot an ICRPfigure, either ?
Dr. Tarztor. At the request of the United Nations Committee the
ICRPand the ICRU have carried out two special studies dealing with
the question of medical exposureof patients.
Senator ANpERSoN. Whatis the ICRU ?
Dr. Tayzor. That is the International Commission on Radiological
Units. They have put out two published reports on the subject of
medical exposures.
:
Senator Anperson. Dothese figures come from those two published
reports?
Dr. Tayztor. Not the final figures but the methodology and some of
the tentative figures.
Senator Anperson. Where do thefigures come from ?
Dr. Taytor. I was not able to attend the U.N. meetings.
Senator Anperson. This is your paper, Doctor?
Dr. Taytor. Yes. I have their written material. I was not able
to attend their meetings.
Senator Anperson. Where did you get the figures?
Dr. Txytor. From their written material.
Representative Price. Specifically what organization ?
Dr. Tayzor. From the ICRP and the ICRU reports prepared for
the United Nations Scientific Committee on the Effects of Atomic
Radiation.
Representative Hosmer. But you did not independently evaluate
the data and assumptions upon which the conclusions were made?
Dr. Taytor. Thatis correct.
Representative Hosmur. So that you cannot certify to this 10 to
50Percent figure?
r. Tayxor. No, sir; I cannot. I am quoting figures prepared
for UNSCEARby the ICRP and the ICRU.
Senator Anperson. Can you tell us whether the U.N. figure of 120
is based on the United States only ?
Dr. Taytor. Yes, it was. It was based on the 1956 Laughlin-Pullman figure for the United States.
Senator Anperson. Can you tell us whether the figure of 10 to
50 is based on the United States only ?
Dr. Taytor. No, sir. That meluded other countries.
Senator Anprrsoy. Therefore, the two things are not comparable
atall,arethey? Are they oranges and apples?
Dr. Taytor. The U.S.figure 1s included in that 10 to 50 figure.
Senator Anprerson. I understand. But if I ask you the population
of the United States, you say it is 180 million and I say no,it is 4
billion because that is the population of the world and the U.S. popu-
lation is includedinit, it would be a little misleading.
Dr. Taytor. No, sir. The figures give the average per capita dose.
This is the total dose delivered to all the people, divided by the number
of people so that the size of population does not enter.
Senator Anprrson. Ts it safe to assume that you don’t know which
countries are involvedin this 10 to 50 percentfigure?
Dr, Taytor. I can find out. I gave you the names of some.
Senator Anprrson. But there might be others. The United Nations covers a great manycountries.
The last vote was 2,375 to 1,280
or something like that. I forgot how it came out. It was more
countries than T knew existed. Are all these countries in here?
