This means the alpha decay of polonium-210, the most abundant isotope, will change the polonium atom to an atom of lead-206. The isotope of the atom before decay, polonium-210, is called the parent natural radioactive decay of uranium, which is commonly found in Sierra Nevada granites. Po-210 emits alpha particles, which makes it decay to form a stable isotope of lead. The alpha particles carry high amounts of energy which can damage or destroy genetic material in cells inside the body. Po-210 is considered to be one of the most hazardous radioactive materials known, but it must be Polonium-210 emits alpha radiation, which cannot penetrate paper or skin, so external exposure does not pose a health risk. It decays quickly, losing half its radiation in 138 days (its half-life).
