Strontium-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.
These 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.
