ABSTRACT
With the use of a Geiger
proportional counter with sensor tube of Russian and Chinese origin, a comparison
was made in this work between measurements of environmental ionizing radiation with
these detectors and a sodium iodide scintillator activated with TI (Thallium NaI).
Through measurements carried out in a room located inside a tower 25 meters high
on the ITA (Technological Institute of Aeronautics) campus, it was possible to study the efficiency
of the three instruments for the environmental measurement of ionizing radiations
at that location. Between March 7th and June 2nd of 2017, in that region, nine intense
and weak rains were observed with 12 cold fronts coming from southern Brazil. Radiation measurements and the local
meteorology involved are analyzed in this work to verify possible correlations.
KEYWORDS
