Notes |
Polonium has more
isotopes
than any other element, all of which are radioactive. Polonium dissolves readily in dilute acids, but is only slightly soluble in alkalis. |
Polonium is highly radioactive and toxic. Weight for weight it is about 2.5 x 1011 times as toxic as hydrocyanic acid (HCN). A milligram of polonium-210 emits as many alpha particles (helium nuclie) as 5 grams of radium. Polonium has been found in tobacco as a contaminant and in uranium ores. |
