(7) Report on Safety Measures - Operation REDWING Attached is a copy of the remarks presented by Maj. Gen. John C. MacDonald on the Safety Measures - Operation REDWING. Tt is proposed to present to the Japanese government a revised unclassified draft report based on these remarks. The Division of Military Application has agreed to prepare this document for release to the Japanese government and to the US Delegation to the UN Trusteeship Council some time next week. (8) Exchange of Information on radiation standards A conference on radiobiology was held at the request of the Science Council of Japan on November 15-19, 1954. On this occasion the US Delegation was able to provide the Japanese with a considerable body of information regarding US concepts of permissible levels of radioaction exposure and the application of these principles to practical problems. A copy of the report on this conference is attached, . Through informal contacts with the Japanese scientific community, the Division of Biology and Medicine has indicated that it would be receptive to a follow-up conference to be held in the US. It is proposed to issue a formal invitation for a second US-Japan Radiobiology Conference through formal diplomatic channels. Please note that since the November 14, 1954 conference, ther: have been continuing contacts between US and Japanese scientists, unofficially as well as officially, in the field of radiobiology. (9) UN Scientific Committee on Radiation The UN Scientific Committee on Radiation will hold its first meeting March 14. One of its first acts will be to recommend uniform standards with respect to procedures for sample collection and instrumentatio, and radiation counting procedures to be used in analysis of san: *es. The AEC has prepared a preliminary draft proposing uniform standards, which has been passed to the UK for review. It is proposed to submit to the UN for distribution to member nations of the UN Committee a final draft of this proposal next week. Although the Japanese will receive a draft through this official channel, we plan to forward. to Dr. Masao Tsuzuki, the Japanese representative, a copy as soon as it is available. Mr. Merril Eisenbud, Manager of the New York Operations Office, has indicated that the proposal will be ready for distribution on February 27. We are also prepared to offer to Japan, as well as to other member states, US technical assistance in the establishment of collection stations and in training in methods of analysis of radiation samples. We feel that it would be in the interest of the US if tentative standards were approved by the UN Committee and if collection stations were established pricr to the tests. ~ 5 - Enclosure III
