Query: Dosimetric characterization of a new 192Ir pulse dose rate brachytherapy
  source with the Monte Carlo simulation and thermoluminescent dosimeter   In this study, recommendations of the AAPM TG- 43 (U1) report have been
followed to characterize the new 192Ir pulse dose rate source, provided by the
Applied Radiation Research School, Nuclear Science and Technology Research
Institute in Iran. Dose rate constant, radial dose function, geometry factors,
and anisotropy function were calculated according to the relevant American
Association of Physicists in Medicine AAPM and TG43 (U1) reports. In this
study, 192Ir source was characterized using Monte Carlo simulation in water
phantom, and in addition, experimental measurements were carried out using
thermoluminescent dosimeters (TLD-100) in plexiglass (PMMA) phantoms. The
dose-rate constant for the 192Ir PDR was found to be equal to 1.131 cGyh-1U-1
and 1.173 cGyh-1U-1 with TLD measurement and Monte Carlo simulation,
respectively. Also in this study, the geometry function, radial dose functions
g(r), and the anisotropy function have been calculated at distances from 0.1 to
16 cm. The dose-rate constant of these calculations has been compared with
measured values for an actual 192Ir seed. The results of dosimetry parameters,
presented in tabulated and graphical formats, exhibited good agreement to those
reported from other commercially available PDR 192Ir sources. The results
obtained in this study are in close agreement with the characteristics of the
commercially available 192Ir sources. The results obtained in this study can be
treated as an initial assessment of this source to be employed in the
conventional treatment planning systems subsequent to complementary
investigations.
