The polonium isotope discovered in Litvinenko’s body emits radiation only in the form of alpha particles, which are the charged nuclei of helium atoms. Unlike other forms of radiation, like gamma Polonium is element 84 of the periodic table. Currently, it is used as a radioactive heat source, because polonium is very radioactive due to it's short half life. However, this means that it is not very good as long term energy. Another use would be anti static brushes, for photography. What makes Polonium-210 extremely dangerous is that it has a very short half-life (138 days) and its decay pattern is that it is a heavy alpha emitter. Alpha particles are double-positive helium ions, and when they encounter soft human tissue, like internal organs, they do very bad things to it.

Bismuth-209 is found and then artificially changed to bismuth-210 which then decays to form polonium … A Swiss forensic report of the exhumed remains of ex-Palestinian leader Yasser Arafat today suggests polonium poisoning may have been the cause of death – but what is polonium, and why is it so Just how dangerous is mercury, anyway? With talks underway in Geneva on plans to ban the use of the poisonous substance mercury, you might be surprised to read that it's technically safe to drink It undergoes alpha decay, which is radioactive decay by the release of an alpha particle from a nucleus.

Polonium, when absorbed orally, tends to distribute widely through the tissues of the body, approximating whole body radiation exposure. Polonium is excreted fairly quickly, its effective half-life in the body is about 30 days (mostly due to excretion, but also due to radioactive decay).

By mass, polonium-210 is around 250,000 times more toxic than hydrogen cyanide (the LD 50 for 210 Po is less than 1 microgram for an average adult (see below) compared with about 250 milligrams for hydrogen cyanide). The main hazard is its intense radioactivity (as an alpha emitter), which makes it difficult to handle safely. So long as polonium is kept out of the human body, it poses little danger because the alpha particles travel no more than a few centimeters and cannot pass through skin. But if polonium is The maximum safe body burden of Po-210 is only seven picograms. A microgram of Po-210, which is no larger than a speck of dust, would certainly deliver a fatal dose of radiation. Discovered by Marie Curie in 1898, Polonium-210 is one of 20 known radioactive isotopes of the element, according to Chemistry World. Toxicologists say a single gram of the substance could kill as Polonium-210 must be ingested or inhaled to cause damage - breathing it in, taking it into the mouth or getting it into a wound.
