63Ni is electrically deposited on a rectangular or round non-radioactive nickel backing 0.1 mm thick and covered with a corrosion-resistant layer. 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.
Maximum practical surface activity load is ~ 9mCi/cm2
ISO classification: Ñ43221
Corrosion-resistant Beta radiation sources are suitable for applications with temperatures up to +250 °Ñ in aerial environment and under long-term exposure to moisture.
Recommended working life: 5 years in air atmosphere, 10 years in inert gas atmosphere. Storage in inert gas atmosphere is suggested when not in use.
