ORNL's Larsen appointed to committee

OAK RIDGE, Tenn., Feb. 17, 1997 — I. L. Larsen of the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) has been named to the Water Environment Federation's (WEF) development subcommittee for radionuclides in biosolids.

The WEF is an international not-for-profit educational and technical organization of more than 40,000 water quality experts.

The subcommittee's primary focus will be to aid the Environmental Protection Agency (EPA) and state regulatory agencies in developing appropriate radionuclide limits for biosolids in wastewater treatment plants and the education of municipalities, regulators and the general public on the levels of radionuclides which are found in all municipal waste biosolids.

Other members of the committee include lawyers, certified health physicists and other national authorities in the field of radionuclides in biosolids.

Larsen started at ORNL's Isotopes Division in 1977. Since 1978, he has served as a research staff member in the Environmental Sciences Division.

Larsen's research has focused on natural and anthropogenic radionuclides in marine and aquatic environments and municipal waste biosolids.

He received a bachelor's degree in general science from Portland State College in Portland, Ore., and a master's degree in oceanography from Oregon State University.

Among his honors and awards, he received the Technical Achievement Award for publication in 1989. In 1993 he received the inaugural Environmental Sciences Distinguished Achievement Award and was granted a patent for co-development of a radiation detector.

Larsen lives in Oak Ridge with his wife, Gloria. They have five children: Erik, Kristin, Kirk, Sonja and Darren.

ORNL, one of DOE's multiprogram national research and development facilities, is managed by Lockheed Martin Energy Research Corp.
