Bilateral ureteral inverted papilloma with synchronous transitional cell tumor of the bladder

A procedure for measuring the power of an ambient and goal-oriented equivalent scattered radiation dose in the radiation control of X-ray rooms. The procedure is based on the concept of the effective solid angle of a dosimeter directivity diagram. The plots of the angular response of a S2010 selective X-ray dosimeter for studying the radionuclides 119Sn, 241Am, 57Co are exemplified. The scaling factors for dosimetric reading for isotropic and nonuniform fields of radiation were calculated from the obtained values of effective angular solid angles (0.7, 0.8, 1.2 pi).
