The use of BF/sub 3/ counting tubes measuring humidity by the activation of certain nuclides, has the advantages of reproducibility and simple equipment. Thin Rh foils are used as activation indicators, and 10 mC Ra/sup 226/ + Be is used as the neutron source. The assembly of source and Rh foil is placed either in a water-filled container or in a paraffin block surrounded by a layer of borax. The degree of activation of Rh is inversely proportional to the humidity. (P.C.H.)
