Effects of Ionizing Radiation (BEIR-3) Committee, as well as the Interagency Task Force on Ionizing Radiation, which the Veteran's Administration relies upon. Another important development since the last Committee hearing is the finding by the Centers for Disease Control that ex-servicemen who witnessed the SMOKY atomic test in 1957 have a three to four-fold increase of leukemia as well as a ten-fold increase of a rare form of bone marrow disease similar to leukemia. Finally, evidence has been mounting since the last hearing which suggests that low-level ionizing radiation--the type of radiation many of our former veterans were exposed to--causes many degenerative diseases besides cancer and thyroid nodules, including chromosome changes which can lead to sterility and birth defects among the children of atomic veterans. All of these aforementioned current scientific discoveries shall be expanded upon in the following sections. CONTROVERSY OVER JAPANESE A-BOMB DATA According to researchers at the Lawrence Livermore weapons laboratory in California and the Oak Ridge National Laboratory, some of the most important data on the effects of ionizina radiation on humans may be wrong. 1981 issue of Science, In an article in the May 22nd, a consultant who is workina on this research said that the dose revisions “are moving in the wrong direction"--a direction that will cause great concern among the advocates of nuclear energy.
