ruby problem

about 75% have had their fractures filled with lead/glass filler.
now the problem. there are 93 radio isotopes of lead. some have extremely short half lives ( less than 2.2 years. ) which means everytime the peak halflife happens, the radioactivity is at its highest level. my personal favorite i was gonna show someone in the morning. i measured its alpha or beta decay in the morning and saw it was reading a false negative. that afternoon i measured it agn, and i had already missed most of the show. its discovery was at the level 18/11. the morning of question it was reading 6/11. that afternoon it was at 16/11. just kidding. this is cool as shit. theres a 1/93 chance mine comes from a different universe, if its pb208. and whats realy cool is except for ti205, theyre saying all these radioisotopes will dissolve into mecury at some point in time.

If I'm not mistaken Au will decay to Pb in time

you are correct! you are mistaken.

lets use simple logic PR. EVERY AU53 confederate gold coin out there and ALL the older nice gold wouldve tarnished by now if what you said was even remotely true
