Two methods of analysis were used to determine the LD 50/30. Results were compared with those of other experiments using 250 kv.p. x-rays. Loren C.

The United States Air Force School of Aerospace Medicine (USAFSAM) is the United States Air Force (USAF) organization focused on education, research, and worldwide operational consultation in aerospace and operational medicine. USAFSAM was founded in 1918 to conduct research into the medical and physiologic domains related to human flight, and as a school for medical officers trained to support military aviation operations, later coined as flight surgeons. The school supported early military aviation from World War I through the evolution of aviation and into the modern era. USAFSAM actively supported civilian and military manned space missions through clinical and physiologic research. USAFSAM is the oldest continually operating school for flight surgeons and other operational medical personnel of its kind in the world. USAFSAM is located in Dayton, Ohio at Wright-Patterson Air Force Base, and is part of the 711th Human Performance Wing (711 HPW) and the Air Force Research Laboratory (AFRL).…
