AB  - Thallium activated sodium iodide (NaI(Tl)) detector and multi channel analyzer 
      has been utilized to measure gamma rays emitted by radio nuclides found in soil 
      samples of south-west (SW) region of Punjab state, India where elevated level of 
      uranium of around value of 700microg/l in groundwater has been reported. For 
      comparative study, soil samples were also collected and analyzed from west (W) 
      and north east (NE) regions of the state. Uranium and potassium has been found to 
      be comparatively higher in SW region whereas thorium level is higher in W and NE 
      part of Punjab state. Overall concentration level of naturally occurring radio 
      nuclides (40)K, (238)U and (232)Th has been found to be varied from 260.1+/-17.3 to 
      728.2+/-27.7, BDL to 41.9+/-10.3 and 29.5+/-7.1 to 88.1+/-6.2Bq/Kg respectively. Overall 
      average level of (40)K and (232)Th has been found to be higher as compared to 
      world's average concentration level. Average radium equivalent activity 
      (134.8+/-23.03 (sigma) Bq/Kg), dose rate (61.9+/-10.3nGy/h), outdoor and indoor dose 
      (0.30+/-0.05 and 0.08+/-0.01 mSv/year), external and internal hazard index (0.36+/-0.06 
      and 0.42+/-0.08) has been calculated.
