The half-life of a Ba-137 m daughter substance eluted (washed)
out of a Cs-137 isotope generator is measured directly and is also
determined from the increase in activity after elution.
- To measure the activity of the isotope generator as a function
of time immediately after elution.
- To measure the activity of a freshly eluted solution of Ba-137
m as a function of time.
