The internal distribution processes of cadmium ((115m)Cd) in the stems of tomato plants have been investigated using in vivo β-spectrometric measurements with semiconductor detectors. The initial penetration into the xylem after root uptake and the subsequent lateral redistribution in the surrounding tissues were monitored continuously in each individual plant. The kinetics of the lateral migration toward the epidermis can be described by a diffusion process, characterized by an apparent diffusion coefficient of about 10(-8) cm(2) s(-1).

The present experiments indicated the retention of cadmium by the various lobes of the rat prostate following direct injection of radioactive cadmium into the organ.
