Abstract:

An improved formula has been devised for the calculation of gamma-ray dose attenuation in two-legged air ducts through concrete. Comparisons are given between the predictions of the simple empirical formula and the results of measurements as well as predictions obtained by a more complicated computational technique. The accuracy of the empirical formula is discussed. It is shown that the formula is highly accurate, having essentially zero bias and a standard deviation of less than 14 percent of the correct value.
