With difficulty, unless you had access to a nuclear facility or were an authorized user, such as those who use it to generate thermoelectric power. och polonium-210 (210Po) och betaaktiviteten från bly-210 (210Pb), vismut-210 (210Bi) och radium-228 (228Ra). En första indikation på att TID kan vara för hög är att den totala alfa-aktiviteten (förutom radon) överstiger 0,1 Bq/l eller att den totala betaaktiviteten översti-ger 1 Bq/l. Uses Polonium releases a great deal of energy during its radioactive breakdown.

How would one get hold of polonium-210? With difficulty, unless you had access to a nuclear facility or were an authorized user, such as those who use it to generate thermoelectric power. 210 is considered to be one of the most hazardous radioactive materials known, but it must be breathed in or eaten to exert its toxic effects. Your skin or a piece of paper is enough to stop the radiation emitted by Po-210.

Applications. When it is mixed or alloyed with beryllium, polonium can be a neutron source. Beryllium releases a neutron upon absorption of an alpha particle that is supplied by polonium-210. When polonium is discussed in the media, it is usually in the context of the polonium-210 isotope (210 Po). This isotope has a half-life of 138 days, Polonium-210 was used to kill Russian dissident and ex-FSB officer Alexander V. Litvinenko in 2006, and was suspected as a possible cause of Yasser Arafat's death, following exhumation and analysis of his corpse in 2012–2013. Po-210 is used in some industrial applications such as static eliminators, which are devices designed to eliminate static electricity in processes such as rolling paper, manufacturing sheet plastics, and spinning synthetic fibers. It is also used in nuclear weapons production, as a power supply in small satellites, and in the oil industry. Polonium-210 has had other uses, as well.

Polonium may now be made in milligram amounts in this procedure which uses high neutron fluxes found in nuclear reactors. Only about 100 grams are produced each year, making polonium exceedingly rare. Uses Po-210 is used in neutron sources (where it is mixed or alloyed with beryllium). It is also used Title: Polonium-210 Information Sheet Author: The Health Physics Society Created Date: 11/30/2006 9:22:06 AM Polonium-210 is a very strong emitter of alpha particles. A single gram of polonium-210 creates 140 Watts of heat energy and is being considered as a lightweight heat source for thermoelectric power for spacecraft. Polonium-210 has a half-life of 138.39 days. Polonium's most stable isotope, polonium-209, has a half-life of 102 years.

Applications . When it is mixed or alloyed with beryllium, polonium can be a neutron source: beryllium releases a neutron upon absorption of an alpha particle that is supplied by 210 Po. It has been used in this capacity as a neutron trigger or initiator for nuclear weapons.
