Application of the Monte Carlo code DETEFF to efficiency calibrations for in situ gamma-ray spectrometry
چکیده انگلیسی

We studied the applicability of the Monte Carlo code DETEFF for the efficiency calibration of detectors for in situ gamma-ray spectrometry determinations of ground deposition activity levels. For this purpose, the code DETEFF was applied to a study case, and the calculated 137Cs activity deposition levels at four sites were compared with published values obtained both by soil sampling and by in situ measurements. The 137Cs ground deposition levels obtained with DETEFF were found to be equivalent to the results of the study case within the uncertainties involved. The code DETEFF could thus be used for the efficiency calibration of in situ gamma-ray spectrometry for the determination of ground deposition activity using the uniform slab model. It has the advantage of requiring far less simulation time than general Monte Carlo codes adapted for efficiency computation, which is essential for in situ gamma-ray spectrometry where the measurement configuration yields low detection efficiency.

► 137Cs ground deposition levels evaluated assuming a uniform slab model.
► Code DETEFF allows a rapid efficiency calibration.
