Determination of the volumetric dose profile for the irradiation installation in the thermal column of the nuclear reactor is a current problem that requires attention in nuclear engineering. This paper presents a proposal that considers the use of Lithium Carbonate pellets as dosimeters and using the Electronic Paramagnetic Resonance spectroscopy technique to measure the absorbed dose within the thermal column. With the above, neutron dosimetry was carried out in the thermal column of the TRIGA Mark III Reactor, for which it was necessary to establish the appropriate calibration curve. The results obtained show the relevance of the strategy in determining the volumetric dose profile proposed in this paper.

Keywords : Lthium Carbonate Dosimeter; TRIGA Mark III; Thermal Column; Paramagnetic Resonance.
