  1. 1.

    Equations (1) and (2) used for computing the intensity of scattered γ-radiation in gamma-gamma sampling can be used only when long probes are used; Equation (2) is less accurate as far as the diffusion limitation R > L is concerned.

  2. 2.

    Equation (3),proposed by the present authors for computing the intensity of scattered γ-radiation, is not restricted by the limitation R > L and gives satisfactory agreement with the experimental curve for both short and long probes.
