Time optimization of (90)Sr determinations: sequential measurement of multiple samples during decay of (90)Y
This work presents an optimized method for the determination of multiple samples containing (90)Sr when its daughter (90)Y 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...

| Sumario: | This work presents an optimized method for the determination of multiple samples containing (90)Sr when its daughter (90)Y 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 (90)Y is measured during its ingrowth, the gain in total analysis time (time for ingrowth+ summation of measurement times) is not that large, particularly not for low background instruments. However, results for a large part of the samples can be delivered earlier. |
