Abstract
U radu je prikazana nova metoda za odvajanje La-140 od Ba-140 u uzorcima sijena i lucerke u svježim uzrocima fallouta. Primijenjena je amonijeva sol cimetne kiseline.NH4-cinnamate was tested as a reagent for the precipitation and separation of La-140 from forage samples. The precipitate is crystalline, easily filterable, thermically stable, and seems to be a convenient reagent for radiochemical separations. The final precipitate has a formula La(C6H5CH = CHCOO)3
