Abstract

The reaction14N(p, n)14O(71 s) is used, with a proton beam of 14 MeV energy and 100 nA intensity. The14O activity is detected by means of its characteristic 2.312 MeV gamma-ray (9.4%), with a NaI(T1) detector. The intensity ratio of gamma-rays to that of the incident particles for the sample, related to a similar ratio in adequate standards determines the nitrogen content in the sample. The measurement is completely automated. If we protect the embryo region during irradiation, the future germination of the analyzed seeds will be normal. Good correlation has been obtained between the results of the present method and those of the chemical Kjeldahl method.
