Radioisotope sensitivity
Webenergies of about 0.5 to 1 MeV, the optimum radioisotope neutron source for this method is one which comprises a mixture of a-emitter mixed with Be. These sources rely on the reaction 9Be(ct,n)12C for the production of neutrons. Suitable a-emitters include 2ltlAm and 238pu as discussed by Hol-ies (Chapter 3). These sources have an average neutron WebATN on a renal scan typically is diagnosed when there is normal flow but diminished cortical transit of the tracer.
