Radiation affects the environment and local human activity in any location of the earth’s surface. Due to this fact, the aim of this study was to monitor the ionizing radiation and rain intensity using portable devices. During May 23 to October 2, 2015, it was made measures the intensity of gamma radiation from 30 keV to 10.0 MeV at a height of 25 meters in São José dos Campos city, SP, Brazil. It was used a crystal of sodium iodide scintillator 3 × 3 inches coupled to a photomultiplier and associated electronic. The measurements were made continually with minute’s interval throughout the period and it was monitored rain intensity every minute at the same height of the tower. In this job, it was possible to correlate rain-radiation and it was observed which gamma radiation has a directly proportional relationship with rain and visible frequency of 1 day.
