Transfer of radiobiology program to Brookhaven a team effort

By Jeffery Kahn

Decades of study on the biological effects of high-energy heavy charged particles all but came to a halt in the U.S. three years ago when Berkeley Lab, which invented nuclear medicine half a century ago, shut down its Bevalac accelerator.

Although other facilities took up some of the slack when funding ended for the Bevalac, its loss was a blow to charged-particle radiation research. Now, thanks in part to the efforts of the Engineering and Life Sciences divisions, much of what was accomplished in turning the Bevalac into one of the world's finest facilities for heavy-ion radiation biology (see accompanying article) has been transferred to a new facility at Brookhaven National Laboratory.

Life Sciences physicist Jack Miller says creating the new Brookhaven research facility was a two-year labor of love for Bevalac veterans who gave many hours of their own time to the project. Brookhaven's Alternating Gradient Synchrotron (AGS) had never been used for radiobiology, and to do so presented technical challenges similar to those encountered at the Bevalac.

Computer and electronic systems and monitoring devices developed for the Bevalac were refurbished or rebuilt before being moved to Brookhaven. These systems monitor the radiation dose delivered to experimental targets as well as the uniformity and composition of the particle beam, and are critical to the success of accelerator-based biology experiments. Engineering's R.P. Singh was responsible for the software, while Mark Nyman handled much of the electronics engineering. Bernhard Ludewigt of Life Sciences was liaison between biologists and accelerator specialists.

Miller and Life Sciences physicists Lawrence Heilbronn, Cary Zeitlin and Ken Frankel were responsible for installing and running the dosimetry system at the AGS, and Life Sciences biologists Amy Kronenberg and Priscilla Cooper helped design the facility for staging biological samples.

Miller says that the effort to transfer know-how and hardware to Brookhaven really made him appreciate the breadth of resources available at Berkeley Lab. "In addition to engineers and scientists," he said, "we needed computer technicians, electronics specialists, riggers, carpenters and the shipping department, some times on pretty short notice. Everyone came through."

He also praised the staff at Brookhaven for their efforts. "The AGS is optimized for high energy nuclear physics. For radiobiology, the beam had to be dialed down to about 1 GeV/nucleon, well below its comfort zone. This is like getting an internal combustion engine to idle at 20 rpm rather than 700. The accelerator people called this `running in the mud,' but they made it work very well."

The first AGS radiobiology run, using beams of iron ions, took place in October. Forty-one scientists from 12 institutions took part in the highly successful run. Participating LSD researchers included Kronenberg (mutagenesis in human and rodent cells); Cooper and Bjorn Rydberg (DNA damage and repair in human and rodent cells); Mary Helen Barcellos-Hoff (epithelial cell transformation); and Miller (heavy ion fragmentation related to astronaut exposures and shielding).

Radiation biology valuable to astronauts, cancer patients

By Jeffery Kahn

Life Sciences Division researchers, sponsored by DOE, NASA and others, will be major users of the new Brookhaven facility (see main article). Berkeley Lab, in collaboration with Colorado State University, is a NASA Specialized Center of Research and Training (NSCORT) in radiation biology, with a mandate to train some of the next generation of radiation scientists.

Life Sciences physicist Jack Miller says research in this field has particular importance to two groups of people--astronauts and cancer patients. In terms of biological effects, heavy ions are a two-sided coin. While posing a hazard to astronauts, these highly energetic charged particles provide hope to cancer patients.

"We have a lot to learn about the biological effects of densely ionizing radiation such as cosmic ray heavy ions," Miller says. "The knowledge we gain will not only help protect astronauts but will also improve our understanding of both the basic biology and the therapeutic uses of these particles."

To date, astronauts have not traveled much beyond the safety of the earth's magnetic field. Near Earth, heavy ions are of relatively little concern. However, they may turn out to be a major hazard on interplanetary missions.

For instance, it has been estimated that during a three-year mission to Mars, up to one third of an astronaut's nuclei would be "traversed" by a heavy ion. The very long lead times needed for planning a return trip to the moon or a voyage to Mars dictate that research into the consequences of this exposure be conducted now.

Heavy ions can also be harnessed to attack cancerous tissue. Charged particle radiotherapy--the targeting of a beam of heavy ions on a tumor--was pioneered at this Laboratory and at the Harvard cyclotron, and has spread to facilities in more than 10 countries.

Like x-rays, charged particles are able to pass through tissue. However, whereas x-rays begin to give up their energy as soon as they encounter tissue, charged particles deposit almost all of their energy or radiation dose where they stop. This stopping point can be precisely manipulated to coincide with the location of a tumor through the use of a beam delivery system developed at the Bevalac.

Lab hosts teachers from South Africa

Six math and science teachers from the South African black township of Oukasie arrived in the Bay Area on Feb. 18 to begin a month-long program of workshops, lectures, and hands-on classroom experiences at the Laboratory and in local schools. They made their first visit to the Lab on Feb. 18, meeting with Glenn Seaborg, among others, and attending a reception held in their honor.

The teachers are participating in the South Africa Project, a team effort between CSEE's Bay Area Science and Technology Education Collaboration (BASTEC) and the Berkeley-Oukasie Sister Community Project. The project has been designed to serve as a model for linkages between South African and U.S. science faculties.

While in the Bay Area, the teachers will be updated on cutting-edge science and science education opportunities, and trained to conduct peer workshops. After leaving the Bay Area, they plan to spend three days in Washington, D.C.

Potluck fundraiser for Oukasie community

A potluck dinner to raise funds for the Oukasie, South Africa, community is scheduled for 4-9 p.m. on Saturday, March 2, at the home of Emily Benner at 155 Tamalpais, Berkeley. Donations of $3-5 are requested; proceeds will help fund a teacher training center in Oukasie.

The potluck is sponsored by the Berkeley-Oukasie Sister Community Project and BASTEC. Call 849-1890 for more information.

Physics of Star Trek in free public lecture:

The "Physics of Star Trek" will be the subject of a free public lecture to be given next Thursday evening, Feb. 29, by the acclaimed astrophysicist and author Lawrence M. Krauss. An internationally recognized expert on the connections between particle physics and cosmology, as well as chairman of the Physics Department at Case Western Reserve University and frequent guest on TV and radio programs, Krauss uses the Star Trek universe to provide audiences with a stylish look at the world of modern physics. On Thursday, with the help of slides, props, and video clips, he will deal with topics ranging from time travel to warp drive, the Big Bang, and the search for extraterrestrial intelligence. The 7 p.m. lecture will be given in Sibley Auditorium on the UC Berkeley campus. It is sponsored by the Center for Particle Astrophysics.

National labs to get money for weapons complex cleanup:

DOE has launched a $50 million program to develop new technologies for cleaning up the weapons complex. This initiative, a partnership between the Offices of Energy Research (OER) and Environmental Management (OEM), calls on the scientific community to aid DOE in dealing with the environmental legacy of 50 years of nuclear weapons production. The national labs will have $20 million reserved for them in FY96, while another $20 million is being set aside for university and industrial researchers. The remaining $10 million may go to EPA and NSF scientists. Another $50 million has been projected for FY97 with further increases anticipated. DOE says it expects awards to be in the $100,000 to $300,000 per year range for a typical three-year grant, and a call for research proposals has gone out on the Federal Register. Pre-applications for grants are due Feb. 28 and formal applications are due May 8. The initiative is in part a response to recommendations from the Galvin Report. OER head Martha Krebs said the initiative will help bring together some of the best chemists, biologists, and other scientists from the labs and the universities to "form a community around weapons cleanup problems."

O'Leary says she'll stay if asked:

Energy Secretary Hazel O'Leary told reporters she will remain in office a second term if President Clinton is re-elected and asks her to stay on. Dismissing Congressional criticism of her overseas travel as part of a broader attack by House Republicans on the value of government and public service, O'Leary said, "The reason the criticism plays so well is because people's impression of government employees, especially bigwigs, is that when we travel, the trips are somehow boondoggles." O'Leary added that her friends believe some of the criticism is directed at her because she is an African-American woman working in a non-traditional role. She pointed out that critics described her chartered plane as "Madonna's plane; not the plane that was used by the White House press corps, not the plane that was used by the University of Oregon basketball team, and not a 35-year-old plane that leaks and has a terrible heating and ventilation system."

"The New Explorers" focuses on Argonne:

The history of nuclear energy and the challenges of turning nuclear power from war to peacetime use will be the focus of an upcoming PBS broadcast of "The New Explorers." The program, "Atoms for Peace--The Nuclear Age: What Are Its Achievements ... And Where Did It Go Wrong?" will feature Argonne National Laboratory scientists whose work "images the challenges of the Nuclear Age." It airs 8-9 p.m. ET on Wednesday, Feb. 28 (check local listings).

Ingenuity pays off for medical waste disposal

By Mike Wooldridge

The cost of disposing of Berkeley Lab's medical waste went down last year, thanks to some ingenuity on the part of the EH&S and Life Sciences divisions.

By consolidating adjacent sites where medical waste is picked up, costs were cut from $30,000 in 1994 to $22,000 in 1995, even though the total amount of medical waste increased.

The impetus to improve the system came with a change in contractors in early 1995. The new contractor, BFI Medical Waste Systems, had a different pricing schedule, charging less per pound of waste picked up, but having a higher minimum price for small loads.

"It became much more cost effective for the Lab to combine its pick-up sites," said Gale Moline of EH&S.

Medical waste on the Hill is generally made up of any equipment that comes in contact with blood or other potentially biohazardous material, such as test tubes, pipettes, filters, and tissue culture supplies. Such waste is stored in special red bags in laboratories and picked up at designated locations.

Working with Life Sciences, which generates most of the medical waste, Moline was able to cut the 13 pick-up sites down to eight. This involved installing a locker outside of Bldg. 70A for waste barrels, and combining sites in Life Sciences-heavy areas such as Donner.

Even with consolidation of waste bags, Moline says, the system allows backtracking of individual waste containers to original locations because the new waste contractor has implemented a bar-code system of identifying bags.

Moline says the savings from the simple streamlining should also mean less paperwork.

Contributing to the project from Life Sciences were Stacy Gauny and Mark McCall. n
