| Summary: | The city of São Jose dos Campos is in the state of São Paulo in Brazil. It is a region where are the main industries in Brazil. The Technological Institute of Aeronautics - ITA promotes quality higher education teaching and research especially in aeronautics and space science. Given this relevance, in 2011 to 2019 measurements were made of the low energy gamma ray environmental spectra (0.2 - 10.0) MeV in this region. The main factor influencing this spectrum was local rainfall. Through the increase of radon gas in the intense rainfall that occurred at the site, the increase of gamma radiation in this time interval is detected. Also cold-front passages from the Antarctic and Andean mountain regions have shown variations in the low-energy gamma radiation intensities in the region. Other influences become less important. |
