Beta radiation sources: Nickel-63 / Ni-63

63Ni
Radionuclide characteristics
Half-life, days: 36962.51 ± 54.79
Beta particle energy:

βmax 66.945±0.005 keV (100%)
β 17.425±0.006 keV

Reference data:
Nuclear Data Sheets 92, 147 (2001)
63Ni is electrically deposited on a rectangular or round non-radioactive nickel backing and covered with a protective nickel layer. A variety of sizes, shapes and activities are available on request. Sources can be shipped in customer supplied holders. Sources are characterized by ionization current measured in a flat free-air ionization chamber.
Radius of a cylindrical source couldn’t be lower than L/2π, L – source length. Ionization current for cylindrical sources is measured before rolling.
