The sands of the Meaípe beach, in Guarapari (ES) are monazite - type of sand with high natural concentration of heavy minerals. The thorium (232Th) is found in these sands and decays in several child nuclei, one of which is radioactive, colorless, odorless and inert natural gas called radon (220Rn). Studies carried out under controlled laboratory conditions show that radon therapy can inhibit oxidative damage and enhance antioxidant functions in humans and it is used in the treatment of inflammatory pain such as rheumatoid arthritis or osteoarthritis. However, in natural environments, studies on the inhalation of radon gas point to both benefits and harm to humans due to, perhaps, the lack of knowledge of the dosage of existing natural radiation at a given location and time.
In order to map the displacement of radon gas in the local atmosphere, this project proposes the simultaneous observational measurements of the atmospheric variables of high frequency and low frequency (performed by the USP team) and the intensity of the local radioactivity (carried out by the UFES team) in the surface boundary layer of the region.
In addition to the observational part, it will also be used a coupled ocean-atmosphere numerical model (WRF with the Noah module).
