    "abstract": "Monte Carlo calculations using the codes PENELOPE and GEANT4 have been\nperformed to characterize the dosimetric properties of monoenergetic photon\npoint sources in water. The dose rate in water has been calculated for energies\nof interest in brachytherapy, ranging between 10 keV and 2 MeV. A comparison of\nthe results obtained using the two codes with the available data calculated\nwith other Monte Carlo codes is carried out. A chi2-like statistical test is\nproposed for these comparisons. PENELOPE and GEANT4 show a reasonable agreement\nfor all energies analyzed and distances to the source larger than 1 cm.\nSignificant differences are found at distances from the source up to 1 cm. A\nsimilar situation occurs between PENELOPE and EGS4.",
