bre ey oes . Derry -h. . Koril 20, 1950 conclusions into a hypothetical situation. These were that the monitoring service within a strte or local civil defense organizvaticn would be set up as a separate, specialized function divided into two types of teams-—-Locel survey grouns and mobile groups which would be able to make laboratory analyses of air, water and soil samoles. It was agreed that all civil defense personnel including rescue soauads, firemen, policemen, etc. as well as monitors, should be equipped with the dosimeter described above. Also that the local monitor teams should use the survey instrument with top-scale of 500 r; Gelger counters would be used to make house-to-house surveys whenever such surveys became possitle, probably some days after the actual explosion. Campbell described a "field laborstory" presently under development by the Armed Farces which will be mounted in trucks and equipped to do alpha checks on air and water samples, etc. The group seemed to feel that such mobile laboratories assigned to strategic coastal and other areas would be sufficient in fairly small numbers for this tyre of monitoring service. The Mgure of 100 r for maximum permissible exposure under disaster conditions was suggested by Dr. Andrews. This figure, it was agreed, shovld not te released officially under any circumstances until agree~ ment of many competent people in the field had teen obtained. I pointed out that Or. Shields Warren and Generel Cooney should have an opportunity to comment on this point before any action was taken which would connote, officially or by inference, AEC participation in the determination, Others present stated also that Drs. Failla, Taylor, Stafford Warren, and representrtives of the radiology professicn be apprised and given opportunity to discurs this matter because of its far-reaching implicctions and the probability of great consternction if such a horrendous level were announced without any previous dis cussion. The subject of masks and protective clothing was also discussed. Sentiment was expressed both for and against the equipning of civil defense personnel with masks, coveralls, helmets, gloves, shee coverings, etc. The argument wasput forward that to emphasize these measures for civil defence personnel while prescribing a maximum permissible dose of 100 r was very inconsistent. Wo definite conclusion was reached. The last order of business was a discussion regarding formalization of the group. It was decided shat such a group would be of definite value in civil defense planning and tha it would be established on a more formal basis to include all of the agencies represented at this meeting, plus the Bureau of Standards on a regular basis and other agencies such as the Department of Agriculture, Federal Trade Commission, etc., on a specialized basis when and if subjects were discussed on which their opinions were desired. Accordingly, the NSRB will request by letter to the heads of these agencies the appointment of regular members to the working group, which ag yet bears no official name. pO’ ARCHIVES
