Powell (Jim) Richards, who joined BNL on October 11, 1948, and retired as a senior engineer in the Medical Department on June 30, 1983, died at 92 on April 8, 2010.
The following obituary was written by a Brookhaven Lab colleague, Suresh Srivastava of the Redionuclide and Radiopharmaceutical Research and Production Program, in the Medical Department.
Powell "Jim" Richards, who lived at Cypress Glen, Greenville, North
Carolina, died quietly in his sleep on Thursday, April 8, 2010, at the age
of 92 from complications resulting from a series of strokes.
Walter Tucker (left) and Powell Richards (right) in the picture above, were considered to be the medical radioisotope pioneers at Brookhaven National Laboratory. Tucker, working with Margaret Greene, in 1958 created the first molybdenum-99/technetium-99m generator (pictured on right). Thereafter, Richards enthusiastically continued to foster its development for medicine . At present, more than 80 percent of almost 20 million diagnostic radiopharmaceutical injections, given in the United States yearly, use technetium-99m.
Jim Richards retired from the U.S. Department of Energy's Brookhaven
National Laboratory (BNL) in 1983 where he had worked as a nuclear physicist
since 1948. He specialized in the development and promotion of many
radionuclides, including technetium-99m , for diagnostic and therapeutic
purposes. Many of these continue to be used in hospitals throughout the
world. He was an active member of many professional organizations, in
particular the Society of Nuclear Medicine, and received many awards and
honors over the course of a long and distinguished career. Among these
were the Radiation Industry Award from the American Nuclear Society in 1972,
and the Paul Aebersold Award of the Society of Nuclear Medicine in 1977.
Richards was recognized for “his scientific contributions and unceasing
efforts leading to the introduction, development, and use of technetium-99m
as an imaging isotope in diagnostic nuclear medicine”. He was named Honorary
President of the Third International Symposium on Technetium in Chemistry
and Nuclear Medicine that was held in Montegrotto Terme (Padova), Italy,
during September 6 – 8, 1989. On October 16, 1998, the pharmaceutical
giant Mallinckrodt Medical, which had featured him in their 1977 calendar as
one of “The Founders of Nuclear Medicine,” dedicated a new building to him
at their European headquarters in Petten, The Netherlands, installing a
bronze plaque with his prophetic words, in the nineteen-sixties, about the
isotope: “Technetium-99m should be a useful research tool; it combines a
short half-life and unique radiation characteristics. The absence of beta
radiation reduces the amount of damage to biological systems usually
associated with radioisotopes.”
Jim was born in 1917 in Philadelphia and attended UNC at Chapel Hill in the
Chemical Engineering program. He was an avid athlete, playing soccer, track
and basketball in high school and college. He began his career in 1939 at
DuPont near Wilmington, DE. With war looming, he was hired by the U.S.
government and assigned to Oak Ridge, TN, to work on the development of the
government’s nuclear program. He was ultimately involved in the 'Manhattan
Project,' a top-secret venture to develop the atomic bomb.
Jim’s enthusiasm for research exerted a contagious influence on the numerous
fellow co-workers in the laboratory and on the multitude of scientists who
came to work and train under him. He always posed interesting questions
about the very basics of the chemistry involved in radiopharmaceutical
development, which eventually led all of us to devise simpler, more
practical solutions to complex procedures. To quote one of his former
colleagues: “Jim had an uncanny intuition (usually correct) about how things
worked - sort of Edisonian”.
During his tenure at BNL, Jim also played a central role in the development
of the BLIP (Brookhaven Linac Isotope Producer) facility, which began
functioning in 1972, as part of the Radionuclide and Radiopharmaceutical
Research (R&RR) and Production program at BNL. For over four decades,
initially under Jim’s watch, this program has continued to be a world-class
program. It has made major contributions to nuclear medicine; indeed many of
the radionuclides and/or radiopharmaceuticals developed in this program
have, and continue to be, used in patients for diagnostic and therapeutic
procedures. Examples include the technetium-99m generator, Tc-99m-labeled
radiopharmaceuticals, blood cell labeling kits, thallium-201, iodine-123,
xenon-127, copper-67, tin-117m, and many other radionuclides. For a number
of these developments, the credit goes mainly to Jim Richards.
On the personal side as well, Jim was a highly accomplished and successful
individual. His many positive attributes included a great love for
life and a very close relationship with his family and friends. He
excelled in all the essential qualities of a scientist that include
intuition, imagination, vision, and perseverance. Jim was a thorough
gentleman and extremely considerate of others. He possessed the
enviable ability to make people feel at ease in his presence. I always
found his friendly demeanor nothing short of exemplary. He was always
willing to help his students, colleagues, and friends regardless of how busy
I have had the privilege of knowing Jim for over 30 years, first as a mentor
when I joined the “Technetium Chemistry Group” within the R&RR Program at
BNL in 1975, then as a research colleague until his retirement. I consider
myself as being extremely fortunate to also have enjoyed a very close and
unconditional friendship with him. Jim Richards’ death was a deep personal
Upon retiring from Brookhaven in 1983 Jim moved to New Bern, NC. He and his
wife were active members of the New Bern Golf and Country Club. Two years
following the 1999 death of Shirley, his wife of over 40 years, he moved to
Cypress Glen in Greeneville, NC.
Jim Richards is survived by four children, Fred Richards of New Bern, NC,
Mary Jo Conway of Sarasota, FL, Randy Pitcher of Ft. Lauderdale FL, and Jim
Richards of Philadelphia, PA, seven grandchildren, and ten great

Richards joined the hot laboratory division in BNL’s Nuclear Energy
Department as an associate technical specialist on October 11, 1948. He rose
to associate technical specialist Group Leader in May 1953, then to
technical specialist in July 1956, radio chemistry engineer I in July 1958,
associate engineer in July 1959 and engineer in 1965. In February 1969, he
joined the Department of Applied Science, transferring to the Medical
Department in July 1965. He was promoted to senior engineer in 1979. He
retired from Medical on June 30, 1983, continuing with a guest appointment
through September 30, 1988.
