119mSn sources are prepared on the basis of CaSnO3 matrix, synthesized from 119mSn radionuclide of high specific activity (> 300 mCi/g). Active part is placed in titanium capsule with brazed beryllium window and sealed with laser welding.

Please, pay attention, types of the capsules have been changed.
