Abstract
Radiochromic gel dosimeters in form of layers based on Fricke solution have shown to be a valuable method for in-phantom dose measurements in a mixed BNCT radiation field. Using dosimeters with different isotopic composition it is possible to determine bidimensional distribution of the different dose components. In the last years, the method has been continuously improved, permitting to achieve reliable dose images with areas until 14x16cm2, also in epithermal columns with a relevant spectral component of fast neutrons.
