Mössbauer sources

• Cobalt 57 / tin 119

These sealed sources (according to the ISO C54344 classification) are deployed in metallurgical analysis using the Mössbauer effect.
Mössbauer spectrometry is widely used in physical, chemical and biological applications to determine the structure of materials and interaction mechanisms.

• Technique

The cobalt 57 (57Co) source is prepared by electroplating pure cobalt 57 without a vector onto a fine metal matrix, followed by controlled annealing (thickness = 6 µm, diameter 4-8 mm).
Tin 119 (119Sn) is prepared on the basis of a matrix of tin 119m with a high specific activity (> 300 mCi/g) and purity over 99.9%.
Standard matrices are made from rhodium. Other matrices are available on request. A brazed beryllium window and a titanium-alloy weld made with argon as the carrier gas provide protection against radioactive contamination of the environment.
