The following table (Table 1) summarizes the main dosimeters characteristics with respect to the previous mentioned properties for the market A (above defined). The main results of this analysis is that TLDs come in very small dimensions but don’t allow real time measurement, that means the readout is done after the exposure; diodes show a variation in dose response with temperature, dose rate, than several correction factors to be applied to their signal; MOSFETs demonstrate temperature dependence; ionization chambers are very reliable but too big to guarantee the spatial resolution needed for high technology radiotherapy application and require high voltage, both not ideal when working with patients, while the other solutions are not comparable because they show 2 – Dimensions spatial resolution and none of the other advantageous properties (for example, the dose delivered to the patient is typically too large for the sensitivity of radiographic film which in addition to this is light sensitive).
NARRANDO nanotube dosimeter shows, to the contrary, all the advantages of its substitutive products, and adds new characteristics, because it allows real time measurement, high spatial resolution, working also in absence of applied bias voltage (than the ionization chambers) in smaller device, being the promising technology for current and future in vivo applications.
