    "abstract": "Monte Carlo calculations using the codes PENELOPE and GEANT4 have been\nperformed to characterize the dosimetric parameters of the new 20 mm long\ncatheter based $^{32}$P beta source manufactured by Guidant Corporation. The\ndose distribution along the transverse axis and the two dimensional dose rate\ntable have been calculated. Also, the dose rate at the reference point, the\nradial dose function and the anisotropy function were evaluated according to\nthe adapted TG-60 formalism for cylindrical sources. PENELOPE and GEANT4 codes\nwere first verified against previous results corresponding to the old 27 mm\nGuidant $^{32}$P beta source. The dose rate at the reference point for the\nunsheathed 27 mm source in water was calculated to be $0.215 \\pm 0.001$ cGy\ns$^{-1}$ mCi$^{-1}$, for PENELOPE, and $0.2312 \\pm 0.0008$ cGy s$^{-1}$\nmCi$^{-1}$, for GEANT4. For the unsheathed 20 mm source these values were\n$0.2908 \\pm 0.0009$ cGy s$^{-1}$ mCi$^{-1}$ and $0.311 \\pm 0.001$ cGy s$^{-1}$\nmCi$^{-1}$, respectively. Also, a comparison with the limited data available on\nthis new source is shown. We found non negligible differences between the\nresults obtained with PENELOPE and GEANT4.",
