 Berkeley, A City in History Chapter 7
Berkeley was not only deeply affected by the war and post war period, it also played a major role in creating the nuclear specter that was so much a part of the life and culture of those years.
Berkeley was particularly affected by the African American migration, the city's fl population growing from 3,000 to more than 12,000 between 1940 and 1945.
Berkeley's fl heritage goes back to the arrival of Pete and Hannah Byrne in 1859, but the African American population remained small for the rest of the nineteenth century.

 Berkeley Lab's Nine Nobel Laureates
On the day of the Japanese surrender, Ernest Lawrence, the Director of UC Berkeley's Radiation Laboratory, told his colleague, biochemist Melvin Calvin, that it was "time to do something useful with radioactive carbon." Organizing a team of researchers from Lawrence's "Rad Lab," Calvin attacked the photosynthesis question.
Upon his retirement in 1980, the unique, doughnut-shaped three-story laboratory on the UC Berkeley campus, which houses scientists in that division, was renamed the Melvin Calvin Laboratory.

 Santa Cruz Indymedia: The UC is a prominent site of military research (DOWNLOAD the .pdf)
Today, the three laboratories (including Lawrence Berkeley Laboratory) have a combined UC workforce of 18,000 and operate on federally financed budgets totaling nearly $4 billion.2 Along with nuclear weapons research, LANL and LLNL conduct civilian studies as well, such as energy, space, and medical research.
Under the guise of fundamental scientific research, backed by one of the nations most respected institutes of higher learning, laboratory scientists and bureaucrats are able to continue their legacy of building weapons of mass destruction by abusing the reputation of this university, its faculty, and its students.
The creation of the nuclear weapons laboratories, and the continued management of these factories of destruction by the University of California sets a precedent to other institutions, faculty, and most importantly the impressionable student body that military science is not only important, but somehow ethical and necessary.

 Origin of the Radiation Warning Sign (Trefoil)
The Office of Civil Defense originally intended fallout shelters to use the radiation warning symbol with the circle in the center and the three blades, but this idea was rejected because a fallout shelter represents safety whereas the radiation warning symbol represents a hazard.
The three-bladed radiation warning symbol, as we currently know it, was "doodled" out at the University of California Radiation Laboratory in Berkeley sometime in 1946 by a small group of people.
To me, the magenta symbol is striking similarity to a commercially available radiation warning sign, used before 1947, that consisted of a small red dot with four or five red lightening bolts radiating outwards, a design very similar to that on electrical hazard warning signs.

In addition, complete recovery from sub-lethal injury may not occur in a considerable portion of individuals exposed and this factor of chronic injury may be expected to occur in a much higher proportion of subjects than might be expected from sub-lethal chemical injuries from most, if not all, of the known war gases.
Inasmuch as this accumulation by the plants occurs chiefly in the roots which are relatively sensitive to radiation, it can be readily appreciated that significant areas of ground may be made essentially sterile insofar as their agricultural se is concerned.
Inasmuch as 100 r of total body radiation can be expected to product, in a significant number of individuals, some degree of irreversible radiation damage, it would appear that a flux of gamma rays at this intensity would render such an area essentially unhabitable.

 The Transuranium People: The Inside Story. By Darleane C. Hoffman, Albert Ghiorso, and Glenn T. Seaborg
The Lawrence Berkeley Laboratory (formerly the Lawrence Radiation Laboratory), with which the authors of this fascinating book have long been affiliated during what has been described as a “golden age” of discovery, is the site of the discovery of more transuranium elements than any other laboratory in the world.
Chapter 5, “Berkelium and Californium” (25 pp.), discusses the first elements to be discovered after the transfer of Seaborg’s group from the Chicago Metallurgical Laboratory to Berkeley with emphasis on the use of cation exchange techniques for their isolation.
This is one of the reasons for the controversies and friendly competition between workers at Berkeley and Dubna and elsewhere concerning the discoveries of elements 102 and heavier.

 Emilio Segrè
After a visit to Ernest O. Lawrence's Berkeley Radiation Laboratory, he was sent a molybdenum strip from the laboratory's cyclotron deflector in 1937 which was emitted anamolous forms of radioactivity.
After careful chemical and theoretical analysis, Segrè was able to prove that some of the radiation was being produced by a previously unknown element, dubbed technetium, and was the first artificially synthesized chemical element which does not occur in nature.
While at Berkeley, he helped discover the element astatine and the isotope plutonium-239 (which was later used to make the atom bomb dropped on Nagasaki).

 Radiation symbol
The symbol, in essentially its modern, form first appeared in late 1946 at the University of California Radiation Laboratory in Berkeley where it was used internally as a radiation warning symbol.
In April 1948, at the instigation of J. Kuper of Brookhaven National Laboratory, an Atomic Energy Commission Information Meeting was held at which the now familiar trefoil was adopted along with the unique magenta and light blue color scheme; the light blue was later changed to yellow for better visible contrast.
The original Berkeley design can be found on the Oak Ridge Associated Universities Web site along with earlier signs and later versions and some excellent commentary by Paul Frame of the Oak Ridge Institute of Science and Education.

Dr. Bertram Low-Beer was one of Hamilton's colleague's at UCSF, and likewise had a joint appointment at Berkeley's Radiation Laboratory.] Exactly what the patient was told by the physicians, however, necessarily remains a matter of conjecture, as the AEC's 1974 investigation noted.
