Abstract

The early Miocene Murree Formation, late Miocene Nagri Formation and recent alluvium rockunits are exposed in the sub-Himalayas of the Bagh area, State of Azad Jammu and Kashmir,Pakistan. The Bagh area was badly affected by the Kashmir earthquake of October 8th 2005which, along the Muzaffarabad Fault, deformed both the hanging and footwall blocks. Thecracks, joints, fissures and fractures in houses and bedrocks might have affected theemission of radon to the surface. Indoor radon concentration measurements were carried outin some dwellings of the Bagh area, Azad Kashmir, Pakistan. The measurements were based onpassive integrative detection of radon using CN-85 plastic track detectors in box-typedosimeters. The radon concentration in dwellings was between 50  ±  11.6 Bq·m-3and 167.1  ±  21.4 Bq·m-3with an overall average of 95.1  ±  15.8Bq·m-3(geometric mean  =  93.4 Bq·m-3). The average radonconcentrations in pucka, semi-pucka and kucha houses were 97.6  ±  15.4 Bq·m-3,89.7  ±  15.2 Bq·m-3 and 101.9  ±  15.9 Bq·m-3, respectively. Themean values of radon concentrations in the Nagri Formation, Murree Formation and recentalluvium lithology were 99.3  ±  15.8, 90.1 and 96.2  ±  15.5 Bq·m-3,respectively. The annual effective dose to the Bagh population was calculated as 2.38  ± 0.77 (1.33  ±  0.2 to 4.7  ±  0.5) mSv. The average radon (95.1  ±  15.8Bq·m-3) concentration in dwellings for the inhabitants of the Bagh area wassafe from radon-related health hazards and was within the recommended action level (ICRPpublication 65 (1993) Protection against radon at home and at work, InternationalCommission on Radiological Protection, Ann. ICRP 23(2)).The indoor radonvalues obtained in the present study are more than the world average of 40Bq·m-3 (UNSCEAR (2000) United Nations Scientific Committee on the Effects ofAtomic radiation, Report to the General Assembly, United Nations, New York).
