Beta radiation sources: Krypton-85 / Kr-85

85Kr
Half-life: 10.758 years


Beta particle energy:
 

687 keV
251 keV
Krypton-85 (85Kr). The source is produced in the form of cylindrical titanium alloy or stainless steel capsule with an output window of the same material (0,04 mm titanium alloy or 0,025 mm steel). The filling is the radioactive 85Kr in gaseous state. The capsule is sealed with argon arc or laser welding.
