ENERGY AND ANGULAR DISTRIBUTION OF SCATTERED RADIATION IN A WATER TANK IRRADIATED BY X-RAYS

The spectral distribution of scattered x rays in different directions in a water phantom was studied, with the aid of a NaI(Tl) scintillation spectrometer The primary radiation consisted of heavily filtered x rays from a commercial x- ray generator with a maximum voltage of 300 kv. The experimentally determined spectra, differential in energy and angle, were integrated over all angles to give the photon number flux at different primary energies and water depths. (auth)
