The preparation of no-carrier added Mg-28 (half-life 20.9h, β, r) from a pure Al target irradiated by an a-particle beam has been developed for its biological use. Mg-28 in mice fed the magnesium-sufficient diet had a remarkable accumulation in the kidney, heart, bone and liver. The radioactivity decreased with time in the kidney, heart and blood. The brain uptake was not as high. The radioluminograms presented a accumulation of Mg-28 mainly in heart, kidney, bone and glandula submandibularis in control mouse fed the magnesium-sufficient diet. The radioluminograms of a mouse fed the magnesium-deficient diet revealed high accumulations of Mg-28 in the heart, kidney, gut, and submaillry gland compared with that of control.
