e uranium decay series from U-238 to stable lead (Pb-206) is: U → 234Th → 234Pa → 234U → 230 Th → 26RA → 22RN → 218TH → 214Pb → 214Bi → 214PO 90 210Pb → 10Bi → 210PO → 2Pb 238 has a half-life of 4.5 billion years. Of the other nuclei on the way from U-238 to stable P 5, most are very short-lived (half-lives less than a few months). The exception is radium, w half-life of 1600 years. Marie Curie was given ten tonnes of pitchblende (uranium ore, mos anium oxide) and after several years of chemical processing and purification she isolated sor dium from it. Estimate how much radium there was in the pitchblende for her to extract.
