A stack of layers of materials interspersed with thin dosimeters is exposed at a large enough distance from the machine so that the direction of the incident radiation can be well defined. A set of small spheres containing dosimeters is then constructed and used to check the absorbed dose versus depth closer to the source where no single direction of the incident radiation determines the absorbed dose. The practice includes a discussion of interferences, apparatus, procedure, interpretation of results, precision, and accuracy. The practice is applicable to all machines with photon energy spectra of 100 keV to 20 MeV. (JMT)
