This paper presents a summary of the results for "gamma ray benchmark", proposed by the standard committee 6.2.1 of the American Nuclear Society. The benchmark problems consist of either a cylindrical or a rectangular radwaste source tank surrounded with concrete facility. The each analysis is required to calculate the dose rates at several penetrating positions inside and outside the concrete wall and at a streaming position along the door way. Eleven different organizations participated in the excercise and the codes used involve a variety of the techniques for the solution of radiation transport problems: point kernel integration, single scattering, albedo, discrete ordinates and Monte Carlo method. Intercomparison between calculations are made on the gamma ray dose rates at the prescribed positions. Fairly good agreement is obtained on the whole, but large discrepancies appear in the limited cases.
