摘要:In this study, alpha track detectors have been used to develop a methodology to locate fault lines in Accra, Ghana. Alpha track (LR-115 type II) detectors were used for the soil radon gas measurement in forty two (42) sample pits on 70 m × 100 m of land behind National Radioactive Waste Management Centre (NRWMC), Ghana Atomic Energy Commission (GAEC) and fifteen (15) sample pits on about 300 m × 200 m of land at Dunkonah. Comparison method for the determination of uranium content of the soil with track-etch detectors was used in both studied areas. At Dunkonah, the average soil radon gas concentrations calculated ranged from 10.2±0.5 to 23.0±0.7 kBq/m3 with seven (7) sample pits having very high concentration levels. The average soil radon gas concentrations obtained at NRWMC, GAEC ranged from 6.4±0.4 to 27.5±0.8 kBq/m3 with 20 sample pits having very high concentration levels. The area of high soil radon gas concentration at NRWMC coincided with the fault lines discovered by G.S.D.
