Web23 jul. 2024 · Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly. Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years. WebNatural strontium has a silvery white metallic color with a tint of yellow. It can be found naturally in the soil and seawater, as well as some foods. Seafood is a top source of strontium, but it can also be found in smaller quantities in certain foods like dairy, spinach, lettuce, grains, and beans.
