Biotechnology Timeline

ORNL elevates research efforts to protect people from exposure to unsafe levels of radiation, focusing on radiation tolerance, radiation protection services and training, and the development of new methods to measure radiation exposure. At the same time, concerns about health effects of radiation from reactors, atomic weapons testing, and radioactive elements that enter the body spur the development of a broad biological research program.

The first official shipment of a radioisotope produced at a nuclear reactor, carbon-14, is produced at the Graphite Reactor and shipped to Barnard Free Skin and Cancer Hospital in St. Louis in August 1946. During the program’s first year, more than 1,000 shipments of 60 different radioisotopes are used for cancer treatment and as tracers for academic, industrial, and agricultural research. Thousands of radioisotope shipments from the Graphite Reactor will occur between 1946 and 1963.

Researchers develop analytical separation of the components of nucleic acids (DNA and RNA) based on principles developed during the Manhattan Project. This technology is basic to the subsequent explosive growth of DNA and RNA biochemistry and molecular genetics

Based on results of studies with mice, Liane and Bill Russell—a husband-and-wife research team—inform the medical community that the prenatal stage at which radiation is introduced strongly influences the amount and type of damage to the human embryo and fetus. They make specific recommendations on avoiding risks to human pregnancies from diagnostic X-rays that are then adopted worldwide.

Researchers 3D print a large-scale pavilion for the DesignMiami exposition in Florida using biomaterials. They use polylactic acid (PLA), a biodegradable, thermoplastic polyester, combined with bamboo in a composite that is 20% bamboo and 80% PLA by weight. The result is a printed product that has the properties of wood—the same sound, smell, and touch. The pavilions, entitled “Flotsam and Jetsam,” are the largest structures ever commissioned by DesignMiami for its meeting. 

As part of an effort to develop hardier food and bioenergy crops, ORNL scientists uncover the genetic and metabolic mechanisms that allow certain plants to conserve water and thrive in semi-arid climates.
