✦ Synopsis

A technique is described by which the distribution of radionuclei in histological sections of kidney and liver of male rats are visuafised by nuclear track recording plastic. The particles emitted from radionuclei 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 intraperitonially into rats with activity 609 Bq. The detection efficiency of CR-39 for or-particles emitted from the prepared solution of urenyl acetate was found to be 0.085. The concentration of (z-activity in the ashed samples was found in kidney more than that in liver.
