Fricke dosimeter

Fricke dosimeter

[′frik·ə dō′sim·əd·ər]
(nucleonics)
A radiation dosimeter in which the energy of ionizing radiation is determined from the amount of ferrous ions converted to ferric ions in an aerated acidic ferrous sulfate solution.

Several dosimeters i.e., ionization chambers, thermo-luminescent detectors (TLDs), radiographic films, silicon diode dosimeter, alanine dosimeter, plastic scintillators, diamond dosimeter, gel dosimeter, Fricke dosimeter and so forth, have been investigated for the evaluation of ionizing photons.
There are numerous dosimeters such as ionization chambers, thermo-luminescent detectors (TLDs), radiographic films, silicon diode dosimeter, alanine dosimeter, plastic scintillators, diamond dosimeter, gel dosimeter, Fricke dosimeter and so forth, and are used for the evaluation of ionizing photons.
Diffusion of ferric ions into the gel limits the use of MRI technique for Fricke dosimeters.39 MRI is used to obtain precise 3D dose distribution of polymer gel dosimeters with high spatial resolution.
