Radiation doses in Pakistani houses.
Natural radioactivity in building materials has been measured to determine the external dose equivalent rate due to walls, floor and ceiling. Indoor radon has been measured to estimate the internal dose rate. Occupancy factor was estimated to be 0.3. It is found that the external dose equivalent rate to lungs is less than or equal to the internal dose equivalent rate. Both the external and internal dose equivalent rates in the houses under consideration are less than the background dose equivalent rate value given by UNSCEAR.
