Abstract
During a November 1989 conference on radiation exposure measurement, scientists from what was then the Soviet Union toasted the birth of an arrangement they hoped would grow into a lasting business partnership. A Cleveland company that makes radiation dosimetry equipment such as the exposure badges worn by workers in nuclear power plants, expects to import as many as 100,000 radiation-sensitive disks of synthetic sapphire (aluminum oxide) from the Soviet Union. When doped with carbon atoms, the crystals can monitor radiation levels 40 times fainter than the levels picked up by the lithium fluoride-based materials usually used in the West, a sensitivity that it is hoped will make them the standard in the nuclear industry. Earlier this month the House Science, Space, and Technology Committee, proposed setting up a $200 million foundation to fund Russian research in areas including materials science.
