Use of very short-lived nuclides in nondestructive activation analysis with a fast shuttle rabbit

The use of 0.80 sec^207m Pb for the nondestructive determination of lead is described. The 0.570 MeV gamma-ray activity is measured, and corrections are made to allow for the rapid decrease of the dead-time during the measurements. A sensitivity of about 1400 cps/mg Pb and a precision of ±4 % were obtained with a neutron flux of 5·10¹² n·cm^?2·sec^?1. The influence of possible interferences was studied. The fast shuttle rabbit used in this type of analysis is described.
