WebRadiation exposure can have varying effects, depending on the dose received, and what the exposure was. Certain elements, when the exposure is internal, will deposit in various organs or bones. Radioactive Iodine tends to seek out the thyroid (making it useful in cancer treatment) whereas Strontium-90, which tends to seek out bone and bone … WebThis radioactivity can be used for dating, since a radioactive 'parent' element decays into a stable 'daughter' element at a constant rate. The rate of decay (given the symbol λ) is the …
