Applications

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.

Technical description

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.

Applications

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.

Construction

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).
