Potential Hazards. 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). The radioactivity decays away in about two-and-a-half years.
Po-210 is a radiation hazard only if it is taken into the body through breathing or eating or by entering a wound. This “internal contamination” can cause radiation exposure (irradiation) of internal organs, which can result in serious medical symptoms or death.
