E. Gail de Planque

Eileen Gail de Planque (also Eileen Gail de Planque Burke, best known as E. Gail de Planque; 1944 – September 8, 2010) was an American nuclear physicist. An expert on environmental radiation measurements, she was the first woman and first health physicist to become a Commissioner at the US government's Nuclear Regulatory Commission (NRC). Her technical areas of expertise included environmental radiation, nuclear facilities monitoring, personnel dosimetry, radiation shielding, radiation transport, and solid state dosimetry.

Planque was married to Frank Burke. She lived in New York City, and Potomac, Maryland. Planque died in 2010.

A Fellow of the American Nuclear Society and the American Association for the Advancement of Science, Planque was also a member of the National Academy of Engineering, Association of Women in Science, and the National Council on Radiation Protection and Measurements. She served as president of the ANS (1988–89), and Health Physics Society; as well as the co-chair of Committee for International Intercomparison of Environmental Dosimeters. In the late 1970s, Planque was a US expert delegate to the international committee for Development of an International Standard on Thermoluminescence Dosimetry.

Born in New Jersey and raised in Maryland, Planque earned her bachelor's degree from Immaculata College (Mathematics, 1967), Master's degree from the Newark College of Engineering (Physics, 1973), and PhD from New York University (Environmental health science, 1983). From 1967 until 1982, she worked as a physicist for the Atomic Energy Commission. She joined the Environmental Measurements Laboratory, US Department of Energy as its deputy director in 1982, and was promoted to director five years later. From 1991-95, she was a member of the NRC. In 1997, Planque chaired a planning committee, Celebration of Women in Engineering, which developed conferences that encouraged women to choose careers in engineering and included the development of the website EngineerGirl.
