Abstract

SARTORIS, Carla Eri  and  CALDAS, Linda V.E.. Application of a dosimetric methodology of therapeutic X-ray beams with a Tandem system. Radiol Bras [online]. 2001, vol.34, n.6, pp. 337-342. ISSN 0100-3984.  http://dx.doi.org/10.1590/S0100-39842001000600007.

We developed a Tandem system using a pair of ionization chambers (a cylindrical and a parallel-plate type) to perform X-ray measurements in a medical Institution, in substitution of the routine conventional procedure of determination of half-values layers using absorbers. The results obtained indicate the possibility of application of this method in dosimetric procedures of orthovoltage beams (radiotherapy) as a complementary procedure in a quality control program.

Keywords : X-rays; Ionization chambers; Quality control.
