a TEP TAY JapenGrreneeSennettHennesfekyo Tuesday, ‘ovemLer 16 BEST COPY AVAILABLE The second day of the conference wis devoted to reports from United Stites ind Japinese scientists specializing in these fields on findings soncoming the movemsnt of redioictive fission products in soils, witer and plants,ind uptike of fission materials ty animals, plankton and fish of various species in various environments. Prosiding .t the morning session was Dr. Yasuo Miyake of the dvpan devlepitions at the afternoon session Dr. Walter Claus cf the United States doluprition. Opening the morning discussions Dr. Sterling Eendrick of the United Statis Departnent of Agriculture addressed the conference in dopanese come plimenting the Japan delegition members on having such 2 good conmand of bnelish that mide th:ir reiction to English papers sc swift and curtain, and that his sp:eded the propress of the meeting, Dr. Hendrick was complimented by Dr. Miyake on his fluent and well-phrased Japanese speech. Dr. Hendrick presented the results of rere than 2) research prejects eairri:d on in the U.S. to detemnine the course of radioactive miterials resulting from atomic Fission when appli. d in measursd amcunts to experimental plots and greenhour: plants, Summarizing the eenclusions to ke rearched from these data Dr. Honurick steted thit the sbserntion of radicstrontium and ridiolodin2 is jimpertent. He observ d thit "the important thing we have lewned is that ention fer:ins fission products do not reve about aprreciably in th: seil: that thoy 2cb 1s elsaments common in the soil with resp ct to their uptike by plants; «nd that there is small uptake because the seil is so cufficiontly suppli do witn the cermon elemmts which arc preferr:d by the plants." Pr. Hendrick observed briefly thet h. hid 1o data on the entrance into pinntis of fissicn products which fall upon their loaves and stems; but that tho puneral finding wos that these do not unter much if at all into the plant system, He pointed out that any plant mterial which is prepared such as rice will not be contaminated from this source. Dr. Shingo Mitsui of Tokyo University rospended with published sunmmarias eof his findines regarding uptoake of fission products when applied to the leaves of plants, His findings indicated sane: d-pree of vbserption. Both Mitsui and Hendrick agreed thrt much further study is required in this field to g.t rt the facts, The svcond prper cf the morning wis delivered by Dr. Paul PR, Fearson of the U.S. Atomic Buerygy Comaission. Dr. Fearson, with slides ,raphs, and tables to illustrate, gave the results of scores of U.S. studies on the uptake of fisston mitcri-ls by farm animels, including cattle, sheep ani chickens, and of oxperimnt:l lnboratery animals such as rats and mice. from these studies he presented whit is known concerning the course of five radioc-ctive elorents -— strontiun, iodine, yttrium, ruthenium, mJ cesium -- througn th: orfins of maprmis and fiwl, and inte their rroducts such 1s meat, milk and wes, Dr. Fousen offered no conclusions from the studies, pointing out thet nore werk ig eocing on continually and firm conclusions cannot yet be reached.
