title: Procedures for the assay of alpha-particle emitters in water samples.
abstract: In this paper the problems associated with the "in situ" concentration techniques using MnO2 and Al2O3 as adsorbents are reviewed. Sampling equipments, radiochemical separation procedures, yield tracers, sources preparation and counting methods are described. The different behaviour of Ra, U, Th, Pu and Am is discussed and considered for future speciation studies.
