Description
This work explores the effects of dilution on the retention phenomena of radioactive atoms produced in the Szilard-Chalmers reaction, with a minimum level of gamma radiation coming from the Am-Be source. For the first time, we demonstrate that the 128-I extraction yield, after a sizable post-irradiation time, can be maximized with a suitable dilution. The origin of this curious effect is still unclear; while a role played by some contaminant can not be excluded, an alternative suggestion could originate from evolution of intermolecular interactions recently observed when alkyl-iodides are mixed with ethanol.
