2) 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.

1) For other nuclides, activities and dimensions please enquire using the fax back form.

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.

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.

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 state sonly the activity of the U-238 parent. The alpha surface emission rate consists of the emission rates of all uranium isotopes.

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.
