The radon concentrations in soil samples measured by registrant alpha-emitting radon (222Rn) by using (CR-39) track detector, The uranium concentrations in soil samples measured by using register at fission fragments tracks in (CR-39) track detector that caused by the bombardment of (U) with thermal neutrons from (241 Am-Be) neutron source that has flux of (5 ×103 n cm-2 s-1).
If you are interesting to determine the concentrations of radiosondes that emitting alpha particles so I advised you to using the detectors which sensitive for alpha particles like soil state nuclear track detectors (SSNTDs).
Regards
and wu can measure it using gamma spectroscopy such as Germanium detector HpGe or NaI(Tl) detector Anees A. Al-Hamzawi
Dear Israa,
Natural radioactivity mapping is one of important techniques is generally used for the determination. The all radiological hazard parameters (i.e annual effective dose equivalent, annual gonadal dose equivalent, the absorbed dose rate in air, the radium equivalent activity and the external Hazard Index) can be investigated
