During
2018 the intensity and its variation in time were monitored, every hour the
presence of radon gas in two distinct points near each other in São José dos
Campos, Brazil. One point was situated 25 meters high (ACA tower) and the other
3 meters high (ITA laboratory). Two identical RadonEye RD200 (ionization
chamber) detectors were used calibrated in picoCurie/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
presence. With dry and hot periods, there is increasing in radon gas intensity.
Intense rains during short period of time, there is also increasing in presence
of the radon gas in that site. Fine and continuous rains provoke decrease in the
presence of radon gas measured in the place. Comparisons between radon gas
intensities per hour with gamma and neutron changes between (0-10) MeV of
energy at the same time interval were observed.
