re tH op cp es uA there will be only a single group to deal with rather than a number of observer groups each representing a singie nation. If each nation were allowed to send its own observer group and conduct its own experiments the problems, including control of classified information, of the test organization and other government agencies would be vastly complicated, Furthermore , an observer team of the United Nations assures the best possibility of placing an unbiased judgment before the world audience. The observer group should consist primarily of a team of competent scientists and technicians as required to carry out the necessary experiments, measurements and analyses, It will probably be necessary ror this team to receive a certain amount of training, prior to the demonstration shot, of the method to be used. in the equipment and technique The personnel of the observer team Will either perform all or part of the actual work themselves under the general guidance. and supervision of U. &S, personnel, or. the work will be done by U. S. personnel. under close observation by the observer group. 5. Ideally, the method which is used to demonstrate the fact of reduced fallout should possess the following characteristics: a. High credibility - the results of the demonstration should be convincing to the observer group. b. High reliability - both the weapon and method used should give adequate assurance of success, c. Minimum disclosure of classified information ~- the method should not require the disclosure of classified information, at least of the more sensitive categories. Special care must. be exercised to avoid the possibility that whatever information is disclosed, when taken with information which might already be available or which might become available to other nations, might reveal information of greater sensitivity. d. Minimum cost - the method should not be prohibitively expensive to carry out. - Pp - un @vr148 PIT
