Soil-based radon investigations are of value in correlating radon production and its transportation into buildings through the processes of convection and diffusion. Such studies can help in identifying land areas that pose special concerns. We present preliminary results of soil radon gas measurements at 60 different locations in an attempt to map out the geohazard zone of the city of Muzaffarabad. The seismic geohazard microzonation for the area includes five microzones based on different hazard parameters: a very high hazard zone, a high hazard zone, a moderate hazard zone, a low hazard zone, and a safe zone. Measurements were taken with an active radon monitoring system at the depths of 30, 40, 50, and 60 cm below the ground surface. The results obtained were explained by the lithology of the area. Average soil radon gas concentrations were correlated with the depth from the ground surface and indoor radon values for the study area. No significant correlation was found between soil radon gas and meteorological parameters, however soil radon gas increases as the depth from the surface of the ground grows. The results showed a linear relation between soil radon concentrations with depth from ground surface (R2 = 0.9577). The minimum soil radon concentration (68.5 Bq/m3) was found at a depth of 30 cm in the very high hazard zone, the maximum value (53.300 Bq/m3) at a depth of 60 cm in the seismically safe zone. Measured soil gas radon concentrations at depths of 30, 40, 50, and 60 cm were mapped for high, moderate, and low radon concentrations. Elevated soil radon gas concentrations were found in the safe zone, otherwise considered to be suitable for any type of construction.

Radon Concentrations

<p>Radon is a radioactive gas which emanates from rock, soil and water. Radon concentrations in the<br>atmosphere are generally very low (typically <5 Bq m-3), however it can occur at much higher levels<br>in soil (typically 10’s-100’s kBq m-3), or enclosed spaces such as buildings and caves (typically 10’s-<br>100’s Bq m-3). Exposure to radon and its daughter products is associated with an elevated risk of<br>developing lung cancer. Ireland has a population weighted indoor radon concentration of 98 Bq m-3<br>resulting in an estimated 300 annual lung cancer cases per year, representing approximately 12% of<br>the annual lung cancer cases. A national-scale legislative radon-risk map has a 10 x 10 km spatial<br>resolution and is based exclusively on indoor radon measurements (i.e. it does not contain any<br>geological information). The legislative map satisfies the European Council Directive<br>2013/59/EURATOM Basic Safety Standard, in that it defines “high radon” areas as those where >10%<br>of homes are estimated to exceed the national reference level of 200 Bq m-3. New buildings in such<br>areas are legally required to have a barrier, with low radon permeability installed.</p><p>This research focuses on a karstic region of SE Ireland, which features some exceptionally high<br>indoor radon concentrations (65,000 Bq m-3), even though it is not classified as a “high radon” area<br>on the national legislative map. Here we demonstrate the use of measuring sub-soil radon<br>concentrations and sub-soil permeability, in order to construct a radon potential (RP) map of the<br>area. Extremely high sub-soil radon concentrations (>1443 kBqm-3) and radon potential values<br>(>200) are spatially associated with Namurian shales, interbedded with limestone. Overall, we<br>classify the study area as high radon potential (RP >35) using this technique. We suggest all areas<br>underlain by Namurian shales in Ireland should undergo similar radon potential mapping, and if<br>necessary, should be re-designated as “high radon” areas. If deemed appropriate (i.e. where RP<br>>35), such a designation will help to protect the general public from the harmful effects of indoor<br>radon exposure, and will help to lower the incidence of radon-related lung cancer in these areas.</p>

Radon Concentrations

Taiwan is tectonically situated in an oblique collision zone between the Philippine Sea Plate (PSP) and the Eurasian Plate (EP). Continuous observations of gamma rays at the Yangmingshan (YMSG) station and soil radon at the Tapingti (TPT) station were recorded in the volcanic area and around a major fault zone, respectively, in Taiwan for seismic studies. A number of anomalous high gamma ray counts and radon concentrations at certain times were found. It is noted that significant increases of soil radon concentrations were observed and followed by the increase in gamma rays a few days to a few weeks before earthquakes that occurred in northeastern Taiwan. Earthquakes such as these are usually related to the subduction of the PSP beneath the EP to the north along the subduction zone in northern Taiwan (e.g., ML=6.4, April 20, 2015). It is suggested that the preseismic activity may be associated with slow geodynamic processes at the subduction interface, leading to the PSP movement triggering radon enhancements at the TPT station. Furthermore, the further movement of the PSP might be blocked by the EP, with the accumulated elastic stress resulting in the increase of gamma rays due to the increase in porosity and fractures below the YMSG station. The continuous monitoring of the multiple parameters can improve the understanding of the relationship between the observed radon and gamma ray variations and the regional crustal stress/strain in north and northeastern Taiwan.
