Monte Carlo calculations were carried out with radioactive sources of monoenergetic positron-emitters used in compounds, like FDG ( 18 F), Acetate ( 11 C), and Ammonium ( 13 N), were incorporated into a soft tissue volume, in the aim to estimate the type of particles produced their energies, their mean free paths, and the absorbed dose at different distances with respect to the center of the volume. The volume was modeled with a radius larger than the maximum range of positrons in order to produce 0.511 MeV annihilation gamma-ray photons. With the obtained results the absorbed dose, in various organs and tissues able to metabolize different radiopharmaceutical drugs, can be estimated. The simulation code used was Geant4.Keywords: Positrons, Absorbed dose, Monte Carlo simulation.Se llevaron a cabo cálculos por el Método Monte Carlo con diferentes compuestos de radionucleidos emisores de positrones, tales como el FDG ( 18 F), acetato de carbono ( 11 C), amonio ( 13 N), etc, los cuales fueron incorporados en un volumen de tejido blando, con el propósito de estimar el tipo de partículas producidas y sus energías, los caminos libres medios y las dosis absorbida de radiación a diferentes distancias con respecto al centro del volumen. El volumen de tejido fue modelado con un radio más grande que el alcance máximo de los positrones, luego de producirse el proceso de aniquilación emitiendo fotones de 0.511 MeV. Se obtuvieron resultados de dosis absorbida y alcances máximos para varios órganos y tejidos y diferentes radiofarmacos. El código de simulación utilizado fue el Geant4.

“…The simulations were performed using GEANT 4 [9] code with the GAMOS architecture [10] and tissue optics plugin [11] and were carried out using Mie scattering in the Henyey-Greenstein approximation of the phase function. We adopted a cylindrical digital phantom of 15 mm radius and 30 mm height [12].…”

“…The cross-sectional data and the particle transport method were sourced from GEANT4 physics reference manual [9], and materials are defined by NIST [10]. The bremsstrahlung model utilizes the Begert and Seltzer model [11]. During the simulation, the electron beam was vertically incident on the photon converter at a position 2 mm away from the center point of the incidence plane.…”

Abstract. Medical LINACs (Linear Accelerators) use high energy photon beams to treat deeply located tumors. Generally, neutrons are produced by photonuclear reactions in the head of a medical LINAC using photon beams over 8 MV. Neutrons with high relative biological effectiveness and high permeability can cause many problems in terms of radiation protection. The threshold energy of photons producing neutrons in the head of a medical LINAC is 13.06 MV (Aluminum), 13.38 MV (Iron), 8.06 MV (Gold), and 7.41 MV (Tungsten). In this paper, we aim to analyze the characteristics of a photon converter in a medical LINAC using GEANT4 (Geometry and Tracking). For this, the photon and neutron spectrums of the optimized photon converter with tungsten were simulated with 2-24 MeV electron beams, and the ratio of photons with energies over 7.41 MV was analyzed.
