Po-210 emits alpha particles, which carry high amounts of energy that can damage or destroy genetic material in cells inside the body. Alpha decay is much more easily shielded against than other forms of radioactive decay.

This series of transformations takes place in a time span roughly equal to an hour. Polonium-210 is a decay product of the ubiquitous naturally occurring uranium-238 isotope and is widely distributed in the earth's crust in small amounts; uranium ores contain about 100 micrograms of polonium-210 per ton of uranium ore. Polonium-210 is a decay product radon-222, a naturally occurring radioactive gas (half-life = 3.8 days). Polonium-210 (210Po) belongs to the natural decay series of uranium-238. It is produced at the end of the decay series as a daughter nuclide of the β-emitter lead-210 (210Pb).
