Facts about Polonium

Polonium

Polonium-209 (half-life 103 years) and polonium-208 (half-life 2.9 years) can be made by the bombardment of lead or bismuth with alpha particles, protons, or deuterons in a cyclotron.

Polonium

Polonium is a highly radioactive, toxic element and should be handled with extreme care.

Polonium

Polonium (in common with plutonium-238) has the ability to become airborne with ease.

Polonium

Two papers have reported X-ray diffraction experiments on polonium metal.

Polonium

A single milligram of polonium-210 emits as many alpha particles as 5 grams of radium.

Polonium

Like tellurium, polonium is classified as a metalloid, because its properties are intermediate between those of metals and nonmetals.

Polonium

Polonium (chemical symbol Po, atomic number 84) is a rare, extremely toxic, and highly radioactive chemical element.

Polonium

The maximum allowable body burden for ingested polonium is only 1,100 becquerels (0.03 microcurie), which is equivalent to a particle weighing only 6.8 Ч 10-12 gram.

Polonium

Handling milligram, or even a microgram, amounts of polonium-210 is dangerous and requires special equipment with strict procedures.

Polonium

Polonium is highly radioactive, and all elements from polonium onward are significantly radioactive.

Polonium

To explain this phenomenon, one hypothesis suggests that small clusters of polonium atoms may be ejected during the emission of alpha particles.

Polonium

Polonium is a chemical element that lies in group 16 (former group 6A) of the periodic table, just below tellurium.

Polonium

Some researchers have reported that methyl groups can be attached to polonium by certain microbes or by the chemical compound methylcobalamin.

Polonium

The most widely circulating Malayalam-language newspapers include Mathrubhumi, Malayala Manorama, Deepika, Kerala Kaumudi, and Desabhimani.

Polonium

The maximum permissible concentration for airborne soluble polonium compounds is about 7,500 becquerels per cubic meter (2 Ч 10-11 microcurie per cubic centimeter).

Polonium

A few curies (gigabecquerels) of polonium-210 emits a blue glow, caused by excitation of the surrounding air.

Polonium

Solid polonium can exist in two forms: alpha and beta.

Polonium

The first report of the crystal structure of polonium was done using electron diffraction.

Polonium

According to news reports, his death was linked to "a major dose of radioactive polonium-210 in his body.

Polonium

A very rare element in nature, polonium is found in uranium ores at about 100 micrograms per metric ton (1:1010).

Polonium

Weight for weight, polonium is approximately 2.5 Ч 1011 times as toxic as hydrocyanic acid.

Polonium

Once known as Radium F, polonium was discovered by Maria Sk?odowska-Curie (Marie Curie) and her husband, Pierre Curie, in 1898.
