207 start out and just run through the larce number of fission products. I am sorry thovre ave so many numbers on here, but this summarizes ail of the fission preducts which, during the first tca years, secur in the total mixture with a quantity of one percent or greater, (Siide) This indicates the various fission products in general here, In the general groups here (indicating) on dom, these are the rare earths and these materiais, are indivicual cozponents, in peneral, up in hero I grouped them this way because © actually the plant dces not distinguish and in general tho rare earths are all treated as thouth they were a common kind of elenent, and you can groun othors such as the strontium-caleiun- barium as individual entities. We have been talking about strontium-90. start reading across this table hore, If you there is loss than one percent of the total fission product of strontium-90 at 10 days, 90 days, and by a year with this, it becones 1.8. This strontium-90 does not increase during this time to become 1,5, This merely indicates the general decline of all the rest of this mass of fission products so that the strontiun90 becomes a gradual emerzent material as constituting tko identifiable radioactivity at that timo, _ eee ee What we did then was to chceose certain of these radioactive strontiuns, caesiun, iodine -- choosing some of thes
