Dicranurus Posted May 2, 2009 Share Posted May 2, 2009 I just read a short "article" about vertebrate bones as a source of radon. http://www.nps.gov/history/museum/publicat...ogram/02-05.pdf I have also heard that some petrified woods can be a source of radon. Does anyone knows how about invertebrate fossils for example trilobites?

32fordboy Posted May 2, 2009 Share Posted May 2, 2009 This explains why I glow in the dark. As for inverts, it says it occurs naturally in shales. A lot of inverts are from shales. Nick www.nicksfossils.com Link to comment Share on other sites More sharing options...

A lot of inverts are from shales.Nick Yes, I know that, but "...chemical similarities between the and radon praecursor radium and the calcium component of bone cause radium to concentrated in vertebtares fossils." Is there anything calcium components in invertebrate fossils that can also cause radium to concentreted in these fossils?

ashcraft Posted May 2, 2009 Share Posted May 2, 2009 I would assume that they concentrate in bones becasue calcium and radium both form +2 ions, making them somehwat interchangable in the matrix, swapping places, so to speak. Radium then decays into radon, which is a gas, and works its way out of the fossil. If my assumption is correct (a big if), then trilobites wouldn't gain radium. I assume that their exoskeleton was made of chiton, which is a substituted glucose sugar, and wouldn't contain large amounts of calcium.

Dicranurus Posted May 3, 2009 Author Share Posted May 3, 2009 Ok. There is an another webpage. http://www.helsinki.fi/lehdet/uh/201i.htm "the bones of terrestrial vertebrates contain uranium and thorium." I think this may be related food chain?
