Disease-resistant cauliflower created through nuclear science
International Atomic Energy Agency researchers have helped scientists on the Indian Ocean island nation of Mauritius to develop a variety of cauliflower that is resistant to black rot disease. The cauliflower was developed through innovative radiation-induced plant-breeding techniques employed by the Joint Food and Agriculture Organization (FAO)/IAEA Centre of Nuclear Techniques in Food and Agriculture.

A study was carried out to ascertain the diffusion and adsorption parameter values for tritiated water in contact with palladium-silver cathodic membranes with and without palladium black deposits. It is shown that the amount of diffused and trapped tritium, the retrodiffusion, diffusion coefficient, tritium concentrations in the alloy sublayer, and diffusion layer thickness depend on the applied cathodic potential, temperature, palladium-silver membrane thickness, palladium black deposits on the cathodic surface, and time. With a palladium black deposit on the palladium-silver, the tritium adsorption and diffusion increase. Parameter values including the activation energy are determined from electrochemical impedance spectroscopy, voltammetry, permeation experiments, and chronocoulometry.
