Abstract
The radon emanation rates for materials were measured by using the electros tatic precipitation method as a radon monitor. It was found that a low leve l of radon was emanated from several material components in ELEGANT V. The radon monitor has been developed for the highly sensitive measurements of l ow-level radon concentration. The system was shown to have a sensitivity to radon concentrations as low as 1.6 mBq/m(3) for one day measurement. The s ystem was also used as the radon concentration monitor for the gas inside t he airtight box of the ELEGANT V at Oto Cosmo Observatory. (C) 2001 Elsevie r Science B.V. All rights reserved.
