“…However, as geometry plays an important factor in the accuracy of the simulation the model must be drawn very close to the real situation. This is true for neutron dosimetry as it can be affected by neutrons coming out from human body (albedo neutrons) [19]. Therefore in this study we dive into the characteristics of neutron dosimetry from PTFE-bound MgB 4 O 7 :Dy film calculated using Monte Carlo simulation.…”

Magnesium borate (MgB4O7) is currently being studied as the material for neutron dosimetry. To become a proper dosimeter, magnesium borate is doped with dysprosium as the activator and PTFE (polytetrafluoroethylene) is used as the binder. To estimate the response of PTFE-bound MgB4O7:Dy for neutron dosimetry, Monte Carlo simulation was conducted by PHITS (Particle and Heavy Ion Transport Code System) software. The simulation consisted of dosimeter film of said materials attached to a simplified human phantom. The amount of PTFE ranged from 50% to 90% and the thickness of the film was varied from 0.5 mm to 2.5 mm. The result showed that this film dosimeter had high response to thermal neutrons and low response to fast neutrons, in contrast with the response of human body. Furthermore, it also suggested that the sample with the highest MgB4O7 content had the lowest absorbed dose due to self-shielding effect while on the thicker film, the effect of self-shielding also reduced the sensitivity of this film dosimeter.

If the first decade of the new millennium saw the establishment of a more solid foundation for the use of the Optically Stimulated Luminescence (OSL) in medical dosimetry, the second decade saw the technique take root and become more widely used in clinical studies. Recent publications report not only characterization and feasibility studies of the OSL technique for various applications in radiotherapy and radiology, but also the practical use of OSL for postal audits, estimation of staff dose, in vivo dosimetry, dose verification and dose mapping studies. This review complements previous review papers and reports on the topic, providing a panorama of the new advances and applications in the last decade. Attention is also dedicated to potential future applications, such as LET dosimetry, 2D/3D dosimetry using OSL, dosimetry in magnetic resonance imaging-guided radiotherapy (MRIgRT) and dosimetry of extremely high dose rates (FLASH therapy).
