The core inventories of both fallout radionuclides are an order of magnitude higher than that which can be supported by the direct atmospheric flux at this latitude.The elevated values may be explained by fallout onto the catchment during the winter being delivered directly to the lakes during the annual thaw.
Catastrophists, who collect evidence that the Earth has been subjected to discontinuous and disruptive events, are quick to point out the flaws in radiometric dating results.
A search of Ian Tresman's Catastrophism CD on-line (see link below) will generate 101 different references to radiometric dating in catastrophist literature.
Keep up with this story and more Scientists have tried to develop the krypton dating technique for more than four decades.
In 2011, a team of nuclear physicists at the Argonne National Laboratory in Lemont, Ill., near Chicago developed a new atom counter, the Atom Trap Trace Analysis, which finally made the technique possible.
Krypton is a noble gas that doesn't interact with chemicals. The gas is produced by cosmic radiation hitting Earth and is trapped in air bubbles in the Antarctic ice.
