State that comets may have delivered organic compounds to Earth. Scientists are now able to make age determinations from much smaller samples and to make them much more rapidly than by radioactive counting, but carbon proved to be a considerably more difficult problem for instrumental development than the other cosmogenic isotopes. The occurrence of natural radioactive carbon in the atmosphere provides a unique opportunity to date organic materials as old as roughly 60, years.
