Measurement of 90Sr in Reactor Wastes by Cerenkov Counting of 9oY
Determination of 90Sr in low-level radioactive wastes (LLW) from reactors is difficult because of the presence of so many other radionuclides in samples of interest. This problem was dealt with by radiochemical separation of strontium followed by yttrium separation and Cerenkov counting of the high-energy B-particle emissions of 9oY in order to quantitate s”Sr. Separation of this important nuch...

Time optimization of 90Sr determinations: sequential measurement of multiple samples during decay of 90Y
This work presents an optimized method for the determination of multiple samples containing 90Sr when its daughter 90Y is measured after chemical separation and in sequence, i.e. during its decay. Consequently the measurement times will increase for each subsequent sample, since there has been a longer time for decay before measurement. Compared to a previously published approach, when 90Y is m...
متن کاملCerenkov Counter for In-Situ Groundwater Monitoring of 90Sr
Groundwater contamination from Sr is an environmental challenge posed to present and former nuclear weapons related sites. Traditional methods of extracting groundwater samples and performing laboratory analyses are expensive, time-consuming and induce significant disposal challenges. The authors present here a prototype counter capable of measuring Sr groundwater concentrations in-situ at or b...
