Mössbauer resonance on ¹¹⁹Sn

Description

Mössbauer source active part is based on calcium stannate [CaSnO3] matrix synthesized from high specific activity (> 300 mCi/g) ¹¹⁹ᵐSn radionuclide. Active part is placed into titanium alloy holder with brazed beryllium window and sealed with laser welding.

Attention! Sources with capsule type 6 are available on request only. Before placing an order, please contact our Sales Department for details.
