- During the year 2018 the intensity and its variation in time of gamma, neutrons, and rainfallswere monitored, everyminute the presence of the radon gas in two distinct points and close in 2 kilometers away which other in São José dos Campos, Brazil. One point was 25 meters high (ACA tower) and the other 3 meters high (ITA laboratory). Two identical RadonEye RD200 (ionization chamber) detectors were used, calibrated in the construction company itself in the number of hourly counts in pico Curie/liter (pCi/l) or Bequerel/cubic meters (Bq / m3). These measurements indicate that there is always a day/night variation in the intensity of the local radon gas. With dry and hot periods there is a more increase in radon gas intensity. Intense rains and short period of time there is also increased presence of the radon gas in that place. Fine and continuous rains decrease the presence of radon gas present. Comparisons between radon gas intensities per hour,gamma, neutron and rainfalls at the same time interval were observed.
