Abstract
THE use of Eastman Kodak nuclear track plates, type NTA, in the autoradiographic study of tissue containing thorotrast has been described previously1. Autoradiographs of this type are made as a matter of routine by floating a paraffined tissue section on to a photographic plate. However, during the floating and subsequent contact with wet emulsion, some of the radioactive material is leached out. Moreover, the large opaque clumps of thorium deposits in the tissue make counting of α-tracks in the underlying emulsion difficult.
