The work is devoted to determination of the distribution of gamma-emitting radionuclides in the linear source by the nondestructive method. Contributions of radiation from different sites are calculated analytically for the source of simple geometry. As a source of gamma radiation a chlorinator body with deposits of radionuclides on its inner wall is used.
Calculated values of contribution coefficients, the distribution of activity on the chlorinator sites and the absolute value of the total activity of deposits were obtained.
