It was established through phantom measurements that with an increase of the field size over 400 cm/sup 2/ no measurable elevation of the relative deep dose results with 1 mm Al half value layer and with 1 mm Cu half value layer only a very slight elevation. Details on the size of the scattered radiation for fields of 100 and 900 cm/sup 2/, measured at the phantom surface and at 10 cm depth, were reported. The half value layer is sufficient to characterize the deep dose loss and the scattering radiation since the degree of homogeneity has only a very small effect on both these parameters. An extensive analysis of the radiation intensity curves for the primary radiation bundle and for the scattering radiation mantle as a function of the radiation hardness must still be made. (tr-auth)
