Cs-137/Ba-137m isotope generator
The Cs-137/Ba-137m Isotope generator has been specifically designed for use in experiments in schools, universities and trainings centers to demonstrate the properties of radioactivity including half life.
The Isotope generator (Drawing: VZ-1390-001) can be eluted up to 1,000 times to produce small /aliquots of a short lived radioactive solution. A flask containing 250ml of the necessary eluting solution is supplied with each generator, and the eluting solution is also available separately. The generator contains 33kBq or 370kBq of Cs-137 as the long-lived parent nuclide (half life 30.1 years).
The decay scheme of Cs-137 is shown above.
Eluting solution 250ml (inactive) (0.9% NaCl)
A set of easy-to-handle sources of different radionuclides is available for further experiments on radioactivity. The design of the sources and their activities have been selected to permit effective experiments while minimizing the potential hazard.
The radioactive substance is housed in a recess in an aluminium holder 85mm long and 12mm in diameter. The activity is sealed in a stainless steel capsule (Cs-137, Co-60), incorporated in a metal foil (Sr-90, Am-241) or fixed on a disc (Na-22). The mixed source consists of a stainless steel capsule containing Cs-137, in front of which foils incorporating Sr-90 and Am-241 are placed.
For reference the construction of the sources is shown in drawings VZ-2297-001 and VZ-2297-002. Each source set is supplied in a aluminium storage container (drawing: VZ-2582-001) and each single sources is supplied in a singe hole storage container (drawing: VZ-2583-001).
Ordering information - Source sets
1) The design of these sources has been approved by the Bundesamt für Strahlenschutz (BfS) and can be ordered in Germany without a handling license for radioactive material (Licence No. BfS 01/10 StrlSchV).

AktivLab™ - Demonstration set for experiments on radioactivity
The AktivLab is under technical review and is temporarily not available. We will inform you in our 'What's new' section when it will be available.
AktivLab™ contains everything needed to carry out experiments to demonstrate the fundamental properties of radioactivity. The kit includes detailed descriptions of experiments which are suitable for physics courses and for training professional health physicists. The radioactive source used is a radionuclide generator, similar in principle to generators used in nuclear medicine.
Experiments that are performed with AktivLab include:
- Measuring the half life of Ba-137m
- The absorption of gamma rays in lead
- The inverse square law
- Estimating the activity of a radioactive source
- The statistics of radioactive decay
- Measuring the plateau of a detector
