In order to investigate the extent to which nuclear emulsions can be used in beta-ray dosimetry, depth-dose measurements of Sr/sup 90/- Y/sup 90/ radiati on in Lucite were first made by using a plastlc scintillator (NE102) and a Failla extrapolation ion chamber down to and beyond the beta-ray range. Very good agreement was found between these methods throughout the region of beta rays and bremsstrahlung. Measurements with NTB emulsion, however, proved to be grossly inadequate in regions where the absorbed dose is due mostly to bremsstrahlung. From the depth-dose measurements made with the scintillator, isodose curves were constructed for the particular applicator, covering a doserate range of 10/sup 5/. (auth)
