important this is with regard to harbor considerations and the like. They wish to get a correlation with HD work—~in this connection they would, of course, prefer a shot on the bottom but would try to correlate different types of bottans with H- shots. nn | | Blunda saw no objection to letting H&N do this work if they would do 89 jas] soon as possible and if it were tied dowmas a project so they would write-a’report on it. He thought emphasis should be placed on the fact that this is an rtant effect. LMithe DOD did this, Kingsley would guess it would require something of the order oftwo people and a boat. The photographs include aerial photography anfl/gle asked if they would be willing to let Lookout Mountain take the beforeiand after pictures. Scoville guessed they would. PROGRAM 4 - BIOMEDICAL STUDIES hel Neutron Dosihetry with Mice - (ANCGS, MRDL) jp \ Seoville explaited that this is different from Carter's project in the past where he measnted the mean lethal range. The object here is to put out mice at distance inchepente that might be important from a military point of view—-never mind if 1 get killed at one place and none at the next—-the object is to correla response, Scoville said he wa e physical phenamena with the biological data, and this is the only place h better than a physical one. to admit it but they do not have these d say that a biological method is Ogle mentioned a point whtth was sure they were aware of: as the yleld goes up, the blast and thermalidffects becaze more serious relative to neutron effects, so that if mice are placed where neutrons will hurt then they will be killed by blast and thermali! He thought there were enough neutron measurements made on Ifike that this then. (Scoville pointed out that AFCP do not and they are quite amclous to get it.) tion could be gained fron have the Ivy neutron data, Ogle thought to get the dosages one would want, the mice would have to be around I 0O yds; the high-energy neutron flux will not be mich greater than from ‘Mike, and 1000 yds would be right in the crater. It seemed to him that they be talking of what happens because of the difference in neutron spect fren a fission bomb. To find this out, one would have to be in a region wherdtiere is an appreci~ able high-energy neutron flux and because of the air attemation, this mst be close. py , Scoville said that he had not seen the data fram ikejyet. for a 20-KT bomb, one gets a lethal range of neutrons at 1400 yds.) las Ogle saying that for a 102i bamb the lethal renge is the same? Essentially,
