LAWRENCE LIVERMORE NATIONAL LABORATORY: THIS WEEK AT THE LAB

 LAWRENCE LIVERMORE NATIONAL LABORATORY: THIS WEEK AT THE LAB
 LIVERMORE, Calif., Aug. 20 /PRNewswire/ -- Following is a digest of feature and news stories from Lawrence Livermore National Laboratory which includes a contact name and telephone number: RUSSIAN SCIENTISTS Free-Market Workshop for Russian Scientists
 Russian weapons scientists joined U.S. scientists last month at a lab-sponsored workshop designed to expose the Russians -- most of whom come from nuclear weapons design laboratories -- to the research environment in a market economy. A goal of the three-week "Defense Technology Conversion" workshop was to generate proposals for joint research projects.

 Lab-produced silica aerogels -- a super light-weight solid 98 percent air -- blasted into space last week aboard the space shuttle Atlantis as part of the experimental package on the European Retrieval Carrier satellite. The 16 5-inch-by-5-inch pieces of aerogels are being used to capture micrometeroids -- small particles 1/30th the width of a human hair traveling through space at 22,000 miles an hour -- for study back on Earth.

 Lab researchers are using a powerful laser beam aimed at cosmic debris 60 miles above Earth to create a small, artificial star over the laboratory. This "laser guide star" is used in conjunction with computers and telescopes to develop techniques for correcting atmospheric distortion in Earth-based telescopic images. Scientists estimate the new techniques will allow telescopes such as the 10-meter Keck device atop Mauna Kea in Hawaii to resolve objects 100 times smaller than they now can. (NOTE: a demonstration of the guide star experiment for members of the news media is planned for early one morning next week. An announcement will be made as soon as a date has been chosen.)

 Lab researchers have been testing a variety of chemical protective clothing to develop national standards for the equipment. In the most recent test, researchers used robot-like mannequins to simulate human users as they drenched the suits with hydrofluoric acid, ammonia and chlorine. Suits tested were developed by various U.S. makers, as well as one German firm.
 CONTACT: Paul Conners, 510-294-4817. Radiation and You
 The danger of plutonium has been widely publicized. Human cell damage can result if the material's alpha radiation contacts living tissue through inhalation, ingestion or through a cut. Perhaps not widely known, however, is that this same alpha radiation usually can't penetrate the outer layer of human skin! The lab's Hazards Control Department can tell you all you ever wanted to know about radiation but didn't know whom to ask.
 CONTACT: Paul Conners, 510-294-4817. EDUCATION Students Applying Science
 Two weeks of rubbing shoulders and brains with laboratory scientists lie ahead for 30 of the nation's top physics and engineering students. The collegians arrived Aug. 17 for the lab's Undergraduate Summer Institute on Contemporary Topics in Applied Science. Participants will carry out research projects on topics ranging from laser fusion to defense systems and treaty verification. The program was set up in 1985 to expose undergraduates to applied research and thereby attempt to overcome the growing shortage of applied scientists.
 CONTACT: Gordon Yano, 510-423-3117. ENERGY Reviving Nuclear Power
 Dr. Bertram Wolfe, former general manager of General Electric Nuclear Power, speaks at the lab this week on "Reducing the Risks in the Revival of Nuclear Power." His talk will focus on the long history of reactor experience, institutional barriers and proposed reform in reactor licensing procedures. Wolfe will speak Aug. 21 at 10 a.m.
