• Abstract:

  In the month of February of the last 30 years, the region of São Jose dos Campos in the tropical part of Brazil has an average rainfall intensity of 151 mm. In terms of temperature, the minimum average was 170 C and the maximum average was 300 C. With a lot of cloud cover and frequent rains and little sunshine that month, the variation in ionizing radiation was monitored every month, in every minute. Two Geiger counters were used, one with a Russian tube and the other with a Chinese tube. A sodium iodide NaI (Tl) scintillator was also used, coupled to a photomultiplier and associated electronics. All of these instruments are capable of measuring ionizing radiation between 200 keV and 10.0 MeV. It can be seen from the measurements made by the two Geiger and the scintillator that the detected radiation is related to the intensity of rainfall at the time of the observations.
