Monitoramento da radioatividade alfa relacionada ao radônio-222 em águas de poços da região metropolitana de Curitiba (PR)

Abstract

This research objective was to assess the level of randon-222 concentration in well water of the metropolitan region of Curitiba, Paraná.Current work presents the results of indoor 222 Rn activity ground water samples from artesian wells from aquifers of the region. The studies of radon activity in water were performed using the radon detector for a construction project is implemented. In this case, it is observed that the radon concentrations decrease about 56% in the first water tank and 83% in the second water tank over the well. This fact shows that the actions for mitigation of radon are viable and do not require major modifications to the usual systems of construction.

Naturally-Occurring Radioactive Materials at water treatment plant on the Poços de Caldas Plateau Region, Brazil

“…Another important point regarding the presence of NORM concerns the water supply. Recently, researchers in Brazil have shown an increased interest in radioactivity, such as Fianco (2011) and Corrêa et al (2015), both associated with ²²²Rn in well water. Radioactivity may be present in water sources as a result of natural processes or from disposing of radioactive materials (LAURIA et al, 2007).…”

Investigation of the activity of Rn-222 along a small stream in the Representative Basin of Juatuba - MG

“…In Brazil, researchers have also studied the presence of radon in water, including the mechanics of its transfer from rocks and soils to water, as well as its presence in the alkaline massif of Poços de Caldas and in the Paraná sedimentary basin (BONOTTO; LIMA, 1997). The activity of radon in water has also been studied in the Bauru aquifer (SANTOS; BONOTTO, 2011), in three different regions in the state of Bahia (COSTA; AZEVEDO, 2012), in the municipality of Águas da Prata (BONOTTO; LIMA, 1997), and in the metropolitan region of Curitiba (CORRÊA et al, 2015), among others.…”
