This is the conclusion of Columbia university scien tists engaged in a world-wide study being made of the con centration of radioactive fall out in the bone structure of man. Since the start of the study in 1953, about 9,000 samples of human bone have been obtained. The program is supported by the Division of Ejology and Medicine of the U.S. Atomic Energy Com mission. The scientists say In the fourth report of "Strontium 90 in Man" that human bones would probably not collect as much strontium-90 as had been estimated earlier. Strontium-90 is an isotope pro duced and released into the atmosphere by nuclear ex plosions. The isotope's ability to kill when collected in quantity in the human body has been one of the major reasons to fear for the long-term sur vival of man after a nuclear attack. Publishing their report re cently in Science, the journal of the American Association for the Advancement of Sci ence, the scientists say also that the quantity of strontium-90 in the stratosphere from bomb tests is much less than previously estimated. Dr. J. Laurence Kulp, di rector of the Geochemistry section of Columbia's Lamont Geological observatory in Pal isades, N.Y.; Dr. Arthur R. Schulert, research associate at the observatory, and Miss Elizabeth J. Hodges, research assistant at Lamont, prepared the report. The study concludes that "if 3,000 megatons of fission (an explosive force equal to 3,000 million tons of TNT) were detonated in the North ern Hemisphere, it is prob able that, away from the areas of local and immediate fallout, the long-term stron-tum-90 level in the diet would reach about 180 micro micro curies per gram of calcium, or an equilibrium bone level of 45 micro microcuries. "Thus, under these extreme j conditions, the contamination of non-combatant areas would raise the average level of strontium-90 in t;ie popula tion to the point at which the bone dose from natural sources would be approxi mately doubled (0.60 micro microcuries). "Food grown in the area of intermediate fallout a large portion of the United States-would yield an cqui- j librium of strontium-90 in the diet in the range of 40 to 4,- 000 micro microcuries per . gram of calcium. "These concentrati ons would produce bone levels up to the maximum permissible Red Foothold In Cuba Threatens Latin America By HENRY RAYMONT United Press International San Jose, Costa Rica-IUPD- A Soviet foothold in Cuba threatens every Latin Amer ican nation, Secretary of State Christian A. Herter told Western Hemisphere for eign ministers Wednesday. He warned that Russian in tervention through Cuba woukl create an operational base "designed in the last onalvcic tn overthrow hv ! force every government in the hemisphere. Herter called on the emer gency conference to act now against the threat, saying "it constitutes foreign interven tion no less than does overt armed intervention. ' Herter called on the con ference to vigorously con demn Communist interfer ence in American affairs and to rebuke Cuba for its "tol-j erance and encouragement' nf c,,rh nntsidp intervention. He described foreign-direct-1 ed Communism as "20th cen tury imperialism" and said Soviet Russia and Red China "have made abundantly clear their determination to exploit the situation in Cuba as a means of intervening in lnter ' American affairs." The secretary's decision to maintain a firm stand came 1 as a surprise to many dele gations in view of persistent rpnorts that Cuban Foreign Minister Raul Roa was back ' ina off m-evious threats to condemn the United States concentration for industrial workers even if no special measures were taken. "Thus, long-term ' survival of large populations, even in the countries under attack, would appear to be feasible, provided the serious problem of short-term survival could be solved." The scientists report that "the strontium-90 yet to be deposited is a small fraction of that already down, and the total surface deposit will reach a maximum in 1961." Universe Reported To Be Million Billion Years Old Mexico City, Mexico (Sci ence Service) - The universe may be a million billion years old, not just 12 or so billion years old, an astronomer re ported here. Dr. Fritz Zwicky of Mt. Wilson and Palomar observa tory told the American As tronomical society meeting that a million billion years was the least time required for the formation of galaxies, the vast stellar systems of which the earth's Milk Way is only one of billions. Dr.. Zwicky bases his esti mate for the age of the uni verse on the fact .that atomic nuclei, the building blocks of not build up beyond a cer- matter, react wih one ai;oth,ir and can radiate.. Because atoms react, characteristic groupings of matter are built up. Among these groupings, the stars, of which the sun is only one of mililons with in the Milky Way, are the most prominent. Stars cannot grow beyond a certain size because of de structive effects of the ener gies released when atomic nuclei react, Dr. Zwicky re ported. The next higher units of matter are those of the centers of galaxies. Galactic centers, also, can- tain size because of certain destructive effects. If they could continue building, they would grow in size indefin itely. Since there is a limiting size, however, Dr. Zwicky suggests that the cores of galaxies represent a new unit of cosmic matter, the true character of which has not yet been recognized. This character is, however, "just as distinctive as the character of stars," Dr. Zwicky reported. He described galaxies as follows: Around a dense and very luminous nucleus, a large disk of much lower bright ness is found. The nucleus is some tens of light years in diameter, a light year being the distance light travels in a year at 186,000 miles a sec ond, or some six million mil lion miles. The disk is surrounded first by a scattered "suburban" population of stars, gas and dust clouds that may be lined up along a number of more or less well defined spiral arms. Around this suburban popula tion there may be a faint halo of stars and dark gases. Fin ally there are intergalactic formations hovering around the galaxy. The disk, suburban popula tions, halos and intergalactic formations have dimensions of a few to many thousands of light years, always much larger than the nuclei of galaxies. kidney 'n meat liver 'n meat chicken meaty mix chopped fish mm. r i with our IT'S CANNING TIME!
