1) The natural uranium source contains the uranium isotopes U-234, U-235 and U-238 (daughter nuclides below U-234 have been removed by a radiochemical separation procedure).
U-238 is in equilibrium with U-234; the certificate states only the activity of the U-238 parent. The alpha surface emission rate consists of the emission rates of all uranium isotopes.
2) Calibrated for emission rate only, nominal activity reported
3) For Sr-90/Y-90 sources, the activity quoted on the certificate is that of the Sr-90 parent only. The emission rate quoted is from both nuclides.
4) Sources supplied with EZN certificates comply with ‘Working Class Sources‘ as defined in ISO8769:2020
5) DAkkS certificate are issued by Eckert & Ziegler Nuclitec’s ISO17025 accredited laboratory
6) ‘Class 2 Sources’ according to ISO8769:2020 are supplied with DAkkS certificates, issued by Eckert & Ziegler Nuclitec’s ISO17025 accredited laboratory.
