The 14 MeV neutron activation analysis of Chinese foodstuffs for protein content

A method for determining protein content in foodstuffs by 14 MeV neutron activation analysis for nitrogen is described. The procedure proves to be quite precise, and potentially quite accurate, while only requiring about 7 min per sample. The effect of interfering activities is discussed, and corrections for30P and38K are described. The protein determinations for over 40 Chinese foodstuffs are given.
