The effects of radioactive decay on living organisms (like the human body) can vary depending on the degree of radiation involved. And while low dosage amounts like those encountered in nature are not harmful, high dosage amounts can cause considerable damage in human tissue. When moderate to high doses come into contact with cell molecules, free ions can become lodged in the tissue. and create free radical materials inside the cells.
