1. US negotiators also questioned whether high-altitude tests could evade detection via radiation shielding . 2. Barium borate-fly ash glass can be used as radiation shielding . 3. The best radiation shielding is very mass-intensive for physical reasons. 4. To Radon, specializing in radiation shielding , the presence of anthrax came as a big surprise. 5. Radiation shielding effectiveness increases exponentially with shield thickness, see gamma ray for a discussion of shielding.6. Each CCD array is surrounded by a relatively massive wall, providing heat conduction and radiation shielding . 7. Neutron radiation protection relies on radiation shielding . 8. The concrete vaults provide the radiation shielding . 9. An ideal configuration weighing 200 metric tons with 1 meter of cryogenic radiation shielding and 15 Tesla Magnets. 10. Repairs, if required, would involve wrapping aluminum or other radiation shielding around the base of Genesis'two star trackers.
