Let's look at one radioelement, Technetium. It has 3 relatively long lived isotopes:
Tc97=4.2E+6 years 4.200,000
Tc98=6.6E+6 years 6.600,000
TC99=2.13E+5 years 213,000 (Handbook of Chemistry & Physics, 2006)
Technetium is a colog to Manganese & Rhenium, but is not found in ores of the other 2 which is odd since cologs normally replace the other cologs in minerals. One does not find any technetium in in Manganese ores but Rhenium is found. The only source in which "Natural" Technetium is found is in Uranium & Thorium ores as products of Spontaneous Fission. Even if such were created 6000 years ago with apparent age there should be Tecnetium in the Manganes rocks since its half lives are much longer than 6000 years.
