“…This efficiency can be expressed as a product of three separate factors: the intrinsic detector efficiency ( η 0 ), correction factor for different responses depending on the angle of the gamma ray ( W ), and the correction factor for the geometry of the sample ( G ) ( 9 ):…”

“…InSiCal has four predefined distributions ( 9 ): surface distribution, uniform distribution, exponential distribution, and slab (or step) distribution. Surface distribution assumes that all radionuclides are in an infinitesimally thick layer at the surface.…”

“…Recently, the Norwegian Radiation Protection Authority (NRPA) developed a tool that significantly simplifies the in situ calibration of the detector ( 9 ). Using this tool, which we acquired from the IAEA, we calibrated two field detectors with different efficiencies, made by different manufacturers, and performed gamma spectrometric in situ measurements at eight locations in Croatia.…”

In situ gamma ray spectrometry was developed to quickly measure large areas of land following nuclear accidents. However, a proper calibration of detectors for in situ measurements is a long and complicated process. One tool designed to make this calibration quick is the InSiCal software. We compared 5,000 s in situ measurements with two different HPGe detectors calibrated using the InSiCal software and laboratory measurements of samples collected at the same locations. Our findings suggest that in situ gamma spectrometry using InSiCal software can provide reasonably accurate data, but some improvements are needed.

“…Korea is also conducting a survey to evaluate the radiation background of natural radionuclides for in a radon potential mapping program. The most common methods to evaluate both the natural radionuclides and the dose are in-situ NaI(Tl) and HPGe (High Purity Germanium) γ-ray spectrometry, and HPIC (High-Pressure Ionization Chamber) measurement 6,7 .…”

In this study, in-situ and laboratory γ-ray spectroscopy techniques were compared to evaluate the activity concentration of natural radionuclides in soil. The activity concentrations of U (Ra), Th, andK in the soil in 11 sites were simultaneously measured with in-situ portable HPGe and the NaI(Tl) detectors. In parallel, 55 soil samples collected from these sites were analyzed with a laboratory γ-ray spectroscopy technique (HPGe). A strong correlation was observed between the in-situ and laboratory HPGe techniques with a linear correlation coefficient (R) of 0.99 for Ra andTh and 0.975 for K, respectively. The in-situ HPGe technique shows a strong correlation with the NaI(Tl) detector. γ-Rays cps ofRa, Th, andK of the NaI (Tl) detector were then converted to specific activities (Bq kg unit) in soil using the empirical formulas obtained in this study. The absorbed dose rate in air at 1 m height above ground due to these radionuclides was calculated using the Beck's formula and the results were compared with measured values obtained with an high pressure ionization chamber. The results of the calculated and measured dose rate show a strong correlation of R = 0.96. The reliability and precision of analytical spectroscopy techniques of radioactivity and radiation dose were confirmed in this work.
