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. |
