A practical means of using tritium to authenticate a natural versus a synthetic (petroleum-derived) origin of food and flavoring extracts has been demonstrated. Extracts derived from natural botanicals reflect a tritium content incorporated during th

U and Th data have been obtained by ~,-ray spectrometry on samples from thirty quarry sites in the Elberton batholith, a large (500 km 2) late orogenic (320 Ma) mesozonal biotite granite in the Southern Piedmont, USA. The granite is enriched in the T

A new concept in liquid scintillation counting has been employed in developing an instrument for the purpose of quantitatively measuring low specific activity tritium samples. The instrument design differs from present commercial instrumentation in t

Characteristic x rays have been produced for a variety of samples by bombardment with protons in the energy range from 75 keV to 5 MeV. The experiments were performed with two accelerators. For the low-energy studies (less than 150 keV), a Cockcroft-
