\nStrontium-90, Iodine-131, and Cesium-137 are all radioactive isotopes that can enter the human body through contaminated food and water sources, becoming part of the food chain, and causing various physiological disorders.
\n<\/section>\n
\nThese radioactive isotopes can accumulate in specific organs or tissues due to their chemical similarity to essential elements (Sr-90 to Calcium, I-131 to Iodine, Cs-137 to Potassium), leading to cellular damage and increased cancer risk.
\n<\/section>\n
\nThese isotopes are common byproducts of nuclear fission, released during nuclear accidents (like Chernobyl or Fukushima) or nuclear weapons testing. Their presence in the environment poses long-term health risks through contamination of soil, water, plants, and animals, ultimately affecting humans via the food chain.
