      The following feature is known from the geometrical scattering optics. Suppose, S is a perfectly black spherical surface. If some portion is radiating inward according to the Lambert law, then the rest of the surface has an identical illumunation intensity at any point. This spherical surface feature is proved to be characteristic. In this connection the features of spherical shields, as radiation homogenizators within the simplest ball model surrounded by a shield, are discussed. A possibility to use the optics-geometry dependences analyzed is pointed out.
