Abstract

In order to calibrate vials containing charcoal for measurement of radon, emanation sources of radon were produced in-house using 226Ra salts. Calibrated emanation standards containing solution of 226Ra(NO 3)2 absorbed into inorganic compounds were prepared. The emanation coefficient of 222Rn for these standards vary from 0.23-0.25. The emanation sources were found to be suitable for calibrating radon monitors.
