“…The response of these RCFs to more than one radiation type has been recently evaluated for their proven use as detectors for profile measurement of low energy ion beams [112], as well as for laser accelerated proton beams [113]. While their response to low energy protons has been seen to be independent on the energy in the range 2-10 MeV [113], their response results to be strongly LET dependent [112,114,115]. It should be noted that HD-V2 Gafchromic™ films have a different structure from the other Gafchromic™ films as they feature a 12 µm thin active layer on a 97 µm polyester substrate.…”

Radiochromic films are mainly used for two-dimensional dose verification in photon, electron, and proton therapy treatments. Moreover, the radiochromic film types available today allow their use in a wide dose range, corresponding to applications from low-medical diagnostics to high-dose beam profile measurements in charged particle medical accelerators. An in-depth knowledge of the characteristics of radiochromic films, of their operating principles, and of the dose reading techniques is of paramount importance to exploit all the features of this interesting and versatile radiation detection system. This short review focuses on these main aspects by considering the most recent works on the subject.

“…A feasible alternative is film delamination on one of the faces, exposing the polymeric substrate to the medium and the photon beam. The delamination process has been suggested and assessed for different beam types and qualities, such as alpha particles [ 44 ], medium-energy X-rays [ 45 ], and low-energy heavy-ion dosimeters [ 46 ], removing the energy constraint of the detectable particles. However, in these studies, EBT3 films were not submerged in water since the active substrate is highly sensitive and is easily damaged when in contact with water.…”

This work reports an optimized method to experimentally quantify the Gd-nanoparticle dose enhancement generated by electronic brachytherapy. The dose enhancement was evaluated considering energy beams of 50 kVp and 70 kVp, determining the Gd-nanoparticle concentration ranges that would optimize the process for each energy. The evaluation was performed using delaminated radiochromic films and a Poly(methyl methacrylate) (PMMA) phantom covered on one side by a thin 2.5 μm Mylar filter acting as an interface between the region with Gd suspension and the radiosensitive film substrate. The results for the 70 kVp beam quality showed dose increments of 6±6%, 22±7%, and 9±7% at different concentrations of 10, 20, and 30 mg/mL, respectively, verifying the competitive mechanisms of enhancement and attenuation. For the 50 kVp beam quality, no increase in dose was recorded for the concentrations studied, indicating that the major contribution to enhancement is from the K-edge interaction. In order to separate the contributions of attenuation and enhancement to the total dose, measurements were replicated with a 12 μm Mylar filter, obtaining a dose enhancement attributable to the K-edge of 29±7% and 34±7% at 20 and 30 mg/mL, respectively, evidencing a significant additional dose proportional to the Gd concentration.
