For experiments in determining half-lives.
The isotope generator contains Cs-137, which mainly beta decays to Ba-137m, which then decays by gamma emission to Ba-137. The half life of Ba-137m is approx. 2.6 minutes.
Using the accompanying extraction fluid, a small amount of Ba-137m can be extracted (along with a large amount of inactive Ba-137), while the mother nuclide Cs-137 remains in the generator.
After half an hour, the activity of the extracted sample is low enough to be poured down the drain.
The half life of Cs-137 is approx. 30 years.
The isotope generator's activity is 370 kBq.
Ba-137m can be extracted from the isotope generator up to 1,000 times.
Caution: Use only the original extraction liquid (511205). Using other extraction liquids will void the warranty.
