Electrodeposited Standards

Analytics supplies custom geometry electrodeposited standards for alpha spectrometry. The standards can be prepared on 19.2 mm, 24.1 mm or 47.1 mm stainless steel disks with various active areas. The following mixtures of radionuclides are available:

Natural Uranium, ²³⁹Pu and ²⁴¹Am
²³⁰Th, ²³⁹Pu and ²⁴⁴Cm
²³⁰Th, ²³⁹Pu, ²⁴⁴Cm and ²⁴¹Am
Mixed Alpha "Stock" disk-U-Natural, ²³⁹Pu and ²⁴¹Am - 24.1 mm diameter x 0.6 mm thick stainless steel disk, 24.1 mm diameter active area, 1.7 Bq (100 dpm) per isotope (available to ship in 7 work days).

Single radionuclide standards can be prepared using any of the radionuclides in the mixtures as well as ²³⁸Pu, and depleted or enriched uranium. All standards are calibrated in total alpha emission rate measured by gas-flow or scintillation counting. In addition, mixed standards are certified for individual radionuclides using alpha spectrometry.

⁹⁹Tc calibrated for only beta emission rate is available, and can be prepared on 24.1 mm or 47.1 mm stainless steel disks with various active areas.
