INTERACTIVE INFOGRAPHIC TO UNDERSTAND DYNAMICS ENVIRONMENTAL RADIATION DURING 2017 WINTER IN SOUTHEAST OF BRAZIL

In this article we present a didactic way to discuss the day and night dynamics of environmental ionizing radiation during winter in southeast of Brazil. We developed a simulator made in HTML5. The origin of the ionizing radiation data was by varying the intensity of gamma radiation integrated between 200 keV and 10.0 MeV, from June 28 to September 25, 2017. These measurements were performed at one-minute intervals at an altitude of 25 meters high of soil in a tower in São José dos Campos, SP, Brazil. In the end of August, there was a week with low and moderate rains totaling 27 mm net. There was very cold and during the day the high temperature reaching up to 32ºC, reproducing a desert-like climate. It was possible to monitor the arrival of cold fronts in southeast Brazil and (day / night) cycles using the presence of radon gas in the region. The dynamics of gamma radiation measurements indicate in a simple way the variation of the meteorological parameters very important for the environmental studie
