where significant concentrations of polonium-210 and lead-210 are This category includes radioactive waste with nuclides half-life less than or equal to those

The physical half-life of Po-210 is about 140 days. Physical half-life is a measure of the time required for one-half of polonium, and all are radioactive, but the one occurring most in nature—and the one most widely used—is polonium-210 (210. Po). With a . half-life. of 138 days, it decays to stable lead-206 by the emission of an .

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.
