²⁾ 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. Not available as EZN class 2 source.

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, so the activity is approximately equal to the emission.
