“…Therefore, for the specified limits, additional calculations have been made. From the three pairs of the founded values, including the above, the maximum values of the required indicators are selected [12,20]: ΔE = 5.46%; ΔE H =5.92% (11) Thus, on the basis of the rule of "three sigmas", it can be argued that with an optimal allocation of sources with a probability of 0.9973, the increase of the irradiation dose of the ellipsoid will not exceed 5.46% compared to the average value, and the reduction does not exceed 5.92%.…”
