Brief

Cobalt-57 active part is prepared by electrodeposition of high purity carrier-free 57Co onto a thin (thickess 6 μm or less, diameter: 4 - 8 mm) metal matrix followed with controlled annealing process. Standard matrices are rhodium and chromium. Other matrices are available on request. Active part is placed into titanium alloy holder with brazed beryllium window. Laser welding of titanium alloy holder ensures environmental safety against radiation contamination.
