_Neutron Activation Analysis_, 40 minutes, color, 1964. This film describes the nature, potentialities, and applications of neutron activation analysis. The kinds of neutron sources used and the counting techniques are shown. Examples of applications in crime detection, geology and geochemistry, agriculture, medicine, the petroleum and chemical industries, and the semiconductor industry are shown.

He is now a Senior Fellow at the Carnegie-Mellon Institute of Research at Carnegie-Mellon University in Pittsburgh. He is presently engaged in a project that deals with the applications of nuclear technology to art identification. This is sponsored by the National Gallery of Art and in the past has also received support from the U. S. Atomic Energy Commission and the National Science Foundation. Previously he was a nuclear research chemist with the Phillips Petroleum Company and senior scientist at the Nuclear Science and Engineering Corporation. He has contributed articles on art authentication to a number of journals. For ERDA, in addition to this booklet, he has written _The Mysterious Box: Nuclear Science and Art_, _Lost Worlds: Nuclear Science and Archaeology_, and _Secrets of the Past: Nuclear Energy Applications in Art and Archaeology_. A word about ERDA.... The mission of the U. S. Energy Research & Development Administration (ERDA) is to develop all energy sources, to make the Nation basically self-sufficient in energy, and to protect public health and welfare and the environment. ERDA programs are divided into six major categories: · CONSERVATION OF ENERGY—More efficient use of existing energy sources, development of alternate fuels and engines for automobiles to reduce dependence on petroleum, and elimination of wasteful habits of energy consumption. · FOSSIL ENERGY—Expansion of coal production and the development of technologies for converting coal to synthetic gas and liquid fuels, improvement of oil drilling methods and of techniques for converting shale deposits to usable oil. · SOLAR, GEOTHERMAL, AND ADVANCED ENERGY SYSTEMS—Research on solar energy to heat, cool, and eventually electrify buildings, on conversion of underground heat sources to gas and electricity, and on fusion reactors for the generation of electricity. · ENVIRONMENT AND SAFETY—Investigation of health, safety, and environmental effects of the development of energy technologies, and research on management of wastes from energy production.
