Abstract
A technique is described by which the distribution of radionuclei in h istological sections of kidney and liver of male rats are visualised b y nuclear track recording plastic. The particles emitted from radionuc lei contained within the section are registered as tracks in CR-39. An image of tissue structure is induced superimposed upon particle track distribution by autoradiography. The uranyl acetate was injected intr aperitonially into rats with activity 609 Bq. The detection efficiency of CR-39 for alpha-particles emitted from the prepared solution of ur anyl acetate was found to be 0.085. The concentration of alpha-activit y in the ashed samples was found in kidney more than that in liver.
