Today In Radiation Safety History

On May 16, 1960 the laser was successfully fired for the first time. In a July 7, 1960 press conference in Manhattan, Theodore Maiman and his employer, Hughes Aircraft Company, announced the laser to the world. Maiman was granted a patent for his invention, and he received many awards and honors for his work. Maiman's experiences in developing the first laser and subsequent related events are described in hi

On May 17, 1983 the Oak Ridge Mercury Task Force published their findings of their investigation.

The primary material used in thermonuclear weapons was a form of hydrogen fuel known as lithium deuteride, produced from the lithium-6 isotope. Naturally occurring lithium contains about 7 percent of the lithium-6 isotope, while the rest of it is the lithium-7 isotope. In the 1950s, the Y-12 Plant developed, designed, constructed, and operated an industrial scale production process to separate and enrich the lithium-6 isotopes from lithium-7 isotopes for the production of lithium deuteride.

The separation process that produced most of the lithium deuteride was called Colex, a column-exchange process, in which the lithium isotopes were separated as the lithium was transferred between two chemical phases. One of the phases was an aqueous solution of lithium hydroxide and the other a lithium amalgam, a solution of lithium in mercury. The lithium-6 isotope dissolved more thoroughly in mercury than lithium-7. Lithium amalgam remained in a stable state while in contact with an aqueous solution. In other words, the lithium-6 atoms migrated to the amalgam and the lithium-7 atoms adhered to the lithium hydroxide in the aqueous fluid. Cold War production schedules of lithium deuteride required millions of pounds of mercury, and President Eisenhower authorized Y-12 to use a significant portion of the mercury from the National Stockpile for the Colex process from 1955 to 1963.

It was during this process up to 24 million pounds of mercury was used of which 2 million pounds were lost to the environment. According to a 2016 Department of Energy report the cleanup could cost the tax payers up to 3 billion dollars.
