What are the dangers of polonium?

What are the dangers of polonium?

Pure polonium-210 must be handled very carefully. If swallowed or inhaled, this form can be fatal in very small amounts. Once absorbed into the body it can be many times more toxic than cyanide. The alpha radiation can rapidly destroy major organs, DNA and the immune system.

Why is polonium toxic?

Highly toxic It is radioactive because it emits alpha particles (helium ions). Because these are easily absorbed by other materials, even by a few thin sheets of paper or by a few centimetres of air, polonium has to be inside your body to damage you.

Is polonium still used today?

Polonium is of little use to humans, with the exception of some menacing applications: It was used as a trigger in the first atomic bomb and is also a suspected poison in a couple of high-profile deaths.

What is the half life of polonium 210?

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).

Where do you find polonium?

Polonium in the environment. Polonium is a very rare element in nature. it is found in uranium ores, but none extract it form these ores. Polonium is produced in about 100 g/year by bombarding bismuth with neutrons in a nuclear reactor.

What kind of poison is polonium-210 and what is its natural state?

Polonium-210 is highly radioactive substance and a lethal poison. Polonium is a radioactive chemical element (atomic number 84) that was discovered in 1898 by Marie Curie, who named the element after her country, Poland. In its natural state, at room temperature, polonium is a solid metal with a silver color.
