It is specified that thef wastes must be encased in concrete in steel drums, according to definife, speci- fications, and shipped to the Radiation Laboratory for this serwice, A> somewhat similar plan permits the returnof wastes, properly papked, to ORNL for burial there. It is expected that operation of. these ftwo plans will furnish needed experience and cost data on which to fbase a .gound over-all waste disposal policy. Representatives from AKC emergency monitoring teams wer informed of the amounts of penetrating radiation to which team members fay be subjected in an emergency. As a framework for the officially permissi- ble emergency dose values, it was pointed out that a true emergency dose will necessarily be a function of: the degree of the emergency,J but that. doses of 50-100 roentgens will subject the recipient to possilfle injury, that it would very likely shorten his life span, and especially that it greatly depletes his "reserve" which enables him to withstand fradiation ‘Which he would receive from nature, from atomic energy operatZons, and from X-rays in diagnosis or therapy. On the basis of these cd@nsidera- tions, the officially permissible emergency dose has been setfat 10 roentgens for members of AEC teams, whose members would normalyrecelve some exposure in the course of their daily work, and 25froentgens for members of Civil Defense monitoring teams. . Discussions have been held with interested staff membars regarding the health physics organization to be set up at the new gite. It is expected that the contractor will administer the technica] phases of ‘the organization in contrast to the Arco plan which will opejate site and personnel monitoring through central AEC facilities. On@ problem is the training of personnel which must be carried out in ong of the present AEC installations. - A conference was held at the University of Rochester For the purpose of crystallizing a programof research on plutonium fand radon inhalation, as a complement to the work on injected radioactfive substances which has been set up at the University of Utah. . e Rochester program will get under way as soon as quarters can be provided through laboratory remodeling and construction, plans for which havd@ been approved. . - 22 UNC LA SISTFIE D — —_— ia eee
