“…In contrast, permeable sand and gravel and river terrace deposits often display higher radon potential relative to bedrock because high permeability and surface area facilitates both the release of radon and its flow from the ground into buildings. Chemical composition also plays a role, for example if fragments and mineral grains of uranium-rich granites are included in superficial material, this will lead to high radon in soils and dwellings, especially when these deposits are highly permeable sands and gravels (Appleton, 2005;Scheib et al, 2009). Such transportation of U-rich alluvium can be seen in Figure 3, where the rivers draining the U-rich high-ground of the Peak District (Derbyshire Dome, location labelled on Figure 1), show as blue on the ternary airborne image.…”

This study provides a more comprehensive description of the main bedrock geological units associated with intermediate to high radon potential in England including: granites and associated uranium mineralisation in south west England; Devonian, Carboniferous, Permian and Jurassic limestones and dolomites; Devonian, Carboniferous, Jurassic and Cretaceous sandstones; Silurian, Devonian, Lower Carboniferous and Jurassic mudstones; Jurassic ironstones; and some Triassic breccias and conglomerates. Uranium in soil is elevated over many known radon-prone areas but also reflects the accumulation of U in organic-rich soil and peat. Near surface weathering, bedrock fracturing and former working of the ironstones in the English Midlands are all implicated in increased radon potential on these geological units.

“…Radon as a diagnostic precursor to volcanic eruptions and earthquakes has been -and continues to be -strongly debated and an underlying factor is the necessity to fully understand the behaviour of fluids in the geological substrate (Otton 1992;Appleton 2005). This is illustrated by Cigolini et al (2016), who stress that understanding the behaviour of fluids in hydrothermal systems is a key factor in volcano monitoring.…”

This volume draws together the final outputs of the five-year UNESCO / IUGS / IGCP Project 571 and presents new data on radon in the built and natural environments, radon as a diagnostic tool of geophysical phenomena, reflections and recommendations on the future of radon research and a critique of radon's asserted use as a therapy. In recent years there has been an increasing interest in radon from a range of different aspects and we would suggest that radon science has the potential to be a useful tool in understanding our environment as well as its impacts on human health.Gold Open Access: This article is published under the terms of the CC-BY 3.0 license.

“…The São Miguel Island, located in the eastern group of the archipelago, has one of the most active and dangerous volcanoes of the archipelago, the Furnas volcano. Its activity is marked by the presence of fumarolic ields [14] and extensive soil difuse degassing areas [15,16] that surge the radon concentration increase [17]. In 2014, Silva et al [18] …”

“…During the radon decay process, alpha, beta, and gamma radioactive particles are released and can be inhaled and deposited on the bronchial epithelium of exposed individuals; considering that the alpha particle can disrupt the DNA structure within cells of the lining epithelia, and especially lung cells, exposure to this irradiation can contribute to an increased risk of lung cancer [17].…”

Volcanic activity can cause hazardous efects to the environment and the health of the exposed persons such as an increased risk for the development of several cancers. In geothermal areas, volcanic gases such as radon are continuously vented from the main crater, from fumarolic ields or difused through soil. The continued long-term exposure to radon can enhance the risk of lung cancer being considered the leading cause of lung cancer following tobacco smoking. The chronic exposure to volcanogenic radon requires the development of biomonitoring methods that will assist in the evaluation of the efects of exposure to this genotoxic element. The Human Biomonitoring with the use of exfoliated buccal cells is minimally invasive, and the endpoints of the buccal micronucleus cytome (BMCyt) assay are the biomarkers of efect most recently used to measure genetic damage for the exposure to genotoxic and cytotoxic xenobiotics. The BMCyt assay has been used in a number of occupational studies, and positive results were detected as a consequence of exposure to pesticides, metals, and industrial chemicals that are suspected to cause cancer. Regarding the chronic exposure to volcanic environments, many studies revealed a rise in the numbers of MN in buccal exfoliated cells, indicating an increased risk for cancer. This chapter aims to cover the main health hazards and biomonitoring methods for populations chronically exposed to volcanic environments, allowing an estimate of health risks and to implement risk management measures regarding the exposure to certain compounds.
