Daughters of uranium

WebUnlike uranium (a solid), radon is a gas making it easy to inhale. Radon daughters can also be present as small particles that can also be inhaled. Exposure to radon and radon daughters has been associated with development of lung cancer in miners and is the second leading cause of lung cancer in the United States. WebAround 99.284% of natural uranium's mass is uranium-238, which has a half-life of 1.41×1017seconds(4.468×109years, or 4.468 billion years).[1] Due to its natural abundance and half-life relative to other radioactive elements, 238U produces ~40% of the radioactive heat produced within the Earth.[2]

Webex/ radon is an intermediate step in decay of uranium, can escape crystal through microscopic fracture bc it has a half-life of 4 days Why will the dating be wrong if you lose radon? - Sample will have too much parent relative to daughter product, and calculated age will be too young WebUranium-238 is an alpha emitter, decaying through the 18-member uranium series into lead-206. The decay series of uranium-235 (historically called actino-uranium) has 15 members and ends in lead-207. The constant rates of decay in these series makes comparison of the ratios of parent-to-daughter elements useful in radiometric dating.
