title: Determination of hydrogen content in bulk samples using the neutron activation method.
abstract: The applicability of a new irradiation facility for bulk hydrogen analysis based on the activation method using thermal and epithermal neutrons has been tested for cylindrical samples of 8 cm diameter and 10 cm high. A definite correlation was found between the relative excess flux values, R and the total hydrogen contents, N(H) of the samples. Analytical expressions obtained for R vs. N(H) function indicate the possible use of this method even in the case of approximately kg weight and liter sample dimensions. The large sample has a special advantage if the determination of the hydrogen concentration, C(H) is in question.
