Minimum detectable activity for NaI(Tl) airborne γ-ray spectrometry based on Monte Carlo simulation
The determination of the effective minimum detectable activity (MDA) of radionuclides by a detection system plays an important role in environmental radiation monitoring. In this study, the responses of an NaI...

Advanced Spectral-Ratio Radon Background Estimate in Airborne Gamma-Ray Spectrometry and Calibration Technology
This paper discusses an advanced spectral-ratio method that subtracts Compton scattering rays by using a Fast Fourier Transform rather than trip** ratios and establishes a new radon background estimation mat...

Study on the Energy Spectrum Response of a CdZnTe Detector
In order to study the energy spectrum response of a CdZnTe detector, we firstly measured the temperature dependence and the bias dependence of the main characteristic parameters for both a quasi-hemispherical ...

Study on the γ + X, γ + β, γ + α Coincidence Summing Effects of the Intrinsic Background Instrument Spectrum of a LaBr3(Ce) Scintillation Counter
The energy resolution of a LaBr3(Ce) scintillation counter can reach 2.7% (662 keV) at room temperature. As a radiation measuring device, it has remarkably good characteristics. However, the LaBr3(Ce) crystal has...
