69 we are going all out by saying you can give very sizeable overdoses for a relatively short time without doing any more damage than if you spread it out. So if any of our concepts to date on which we are basing our permissible dose levels are correct, then there is absolutely no chance, or at least an awfully small chance of anything developing from q 8 9 z 5 8 | ~MR. COHN: DR. CLAUS: 11 MR. 12 I don't think there has been any study made of high intensities and short exposures... 10 COHN: These are not high intensities. Relatively high intersities. 12 other products that are bone seekers, There are in high fission yield,that would have to be present based on the present mi fame} 3 2: these levels. 8 a= 3 < , 4 strontium and barium, 15 DR. BUGHER: 16 MR. COHN: Telurium, lithium 103, 106, cerium 101 18 and 144, zirconium 195, which we find in fish, praseodymium 19 143, yttrium 141, barium 140, and lanthanum 141, and iodinium 20 147. 21 DR. BUGHER: 22 Denartment What are some that you would have in mind? 17 ARC for example. MR. COHN: The 106 ruthinium has a year half life No, that is only 19 days, I believe. 23 Oh, 24 lived, anywhere from 10 to 60 days, and they are all 25 present in a fission abundance of from 3 to 6 per cent. of EN Ohi Histori2’S <g one year. I am sorry. All of these arefairly long
