Abstract
Korea Research Institute of Standards and Science (KRISS) is developing a length-compensated proportional counting (LCPC) system as a primary system for standardization of beta emitting radioactive gases. The pilot experiment was performed with 85Kr and the optimized high voltage and pressure were found to be 1700 V and 0.203 MPa, respectively. The total activity of 85Kr was deduced by the length compensation of each count. The expanded uncertainty was estimated to be around 0.8% (k = 2) for the 85Kr measurement.
