Abstract
BETA-TRACK autoradiographs offer advantages over other methods of autoradiography, especially when small quantities of weak emitters such as carbon-14 are used1. If, in addition, the autograph and tissue can be viewed as a unit, a further advantage is gained2. Such preparations permit detection of the characteristic tracks in the presence of heavy background fog; eliminate the problem of spurious interpretation due to the reduction of the silver grains by tissue constituents3; require far less radioactivity for detection than other methods of autoradiography; permit viewing at high magnifying power with consequent localization of radioactivity to small areas; and eliminate matching of tissue and autograph. Beta tracks, due to their tortuous path, do not permit determination of a point source.
