In this paper, the procedure for determination of the mean value of
non-homogenous background radiation and the expression of measurement
uncertainty is considered. The background radiation is described using the
Student's distribution, and the measurement uncertainty using the
Welch-Satterthwaite equation. The proposed algorithm was experimentally
verified under well-controlled laboratory conditions and satisfactory results
were obtained.
