In this collection, correspondence, field studies, reports, scientific data, photographs, and maps document the varied research and policy-making career of Pope A.

His papers contain a wealth of primary source research materials and scientific data related to: environmental and industrial hygiene; radon activity; use of beryllium as a rocket propellant; uranium mining; and toxicological, biological and chemical weapon systems, primarily from the 1950s through the 1970s, especially as related to America's atomic age federal policy.
