  1. THE ANALYTICAL STUDY OF RADON CONCENTRATION IN RIVER WATER IN GAUTENG USING RAD7 Energy Postgraduate Conference 2013

  2. INTRODUCTION

  3. OBJECTIVES • Measure Radon concentration in natural water and soil. • Determine the energy released during the decay process. • Develop portable technique for measuring moderately high level of radon in water. • Compare Radon concentration levels with the international recommended standards. • Prepare regional radon potential maps.

  4. ALPHA DISINTEGRATION

  5. MATERIAL AND METHOD RAD7 • Purge RAD7 until RH is 6% • Test – commercial water • 18 river water samples • Close loop aeration scheme • 3 hours run, 36 recycles Settings: Cycle: 5 minutes Recycle: 36 Mode: Grab

  6. PRELIMINARY RESULTS CUMULATIVE SPECTRUM 6.00 MeV 6.00 MeV 7.69 MeV 7.69 MeV Activity (cpm) Energy (MeV)

  7. RADON DISTRIBUTION Bottled Water Pretoria A1:Valpre Still water A2:Bonaqua Still water A3: Distilled water B1:Saulsville B2: Saulsville B3: Atteridgeville B4: Denville B5: West Park B6: Magnolia Park B7: Hannops (Centurion)

  8. WATER SAMPLE Atteridgeville Rn-222 (Bq/m^3)

  9. RADON DISTRIBUTION Jukskei River C1: Bruma Lake in C2: Bruma Lake out C3: Gilooly’s Farm C4: Dorelan C5: Mooderfontein C6: Cunning Rd C7: Alexandra C8: Buccleuch C9: Vona Valley C10: Jukskei N1 Brdg C11: Kyalami Bridge C12: Woodmead

  10. SUMMARY The radon concentration level in those areas may be due to the presence of Uranium beneath the soil as a result of prospecting

  11. CONCLUSION
