Show " Radiation effects on man still 'aren't clear-cut' radiation. The lecture Friday was one in a series of eight concerning radiation effects on man. Mr Russell said little has been reported about the actualities of research being done to determine effects of radiation on genetics. The first year of scientific inquiry into radiation's effect upon genetics was 1927. In 1927, in spite of Hiroshima and Nagasaki, "we still have seen no clear-cut effects of radiation upon the genetics of man" said Dr. Russell. He said however, that due to clear-cut effects of radiation upon fruit flies and mice, it is fairly certain that genetic mutations in men exposed to various levels of radiation, will show up eventually. Expounding on inquiries into radiation's effects upon genetics to date Dr. Russell compared the wide difference in results between the fruit fly test group and the mice test group. The results or tne test upon the fruit fly group yielded results that were, until 1947, accepted as basic principles of radiation genetics. In 1947, the Atomic Energy Commission Com-mission gave sanction and money to a group of scientists, Dr. Russell among them, to test a group of mice to see if the resultant findings could or could not corroborate the earlier findings of the radiated fruit flies. The findings were vastly different. Since the beginning of the "ban the bomb" movement some years ago, much concern has been voiced about the effects of radiation upon the genetic stability of man. In his lecture, titled "The Genetic Effects of Radiation," W.L. Russell Ph.D., of the Oakwood National Laboratory for Genetic Research, stated that the press has been largely responsible for polarizing both opponents and proponents of furthering the use of radiation quality andthein,ea7beaa,e andconceptionni Dr. Russell "J J-V the results obtained ' 1 thfe factors, and the"tol bween them, r 'me'a , greater complexity in I3 t process than w a, """flined.
