ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

Ian Wall—ANS member since 1964
Ian Wall early in his career . . .
I graduated with a degree in mechanical engineering from Imperial College, London, in 1958. Nuclear power was viewed favorably at the time, so I took a 1-year course on the subject. I was then offered fellowships at Cambridge University and the Massachusetts Institute of Technology and thought the latter would be more interesting, so I moved to Cambridge, Mass., to study nuclear engineering. After completing my doctorate in 1964, I joined the American Nuclear Society and took a job with General Electric, then in San Jose, Calif.
In 1967, GE assigned me to explore the use of probability in reactor safety. At that time, the prevailing opinion was that the probability of a severe accident was infinitesimally small and the consequences would be catastrophic.
