10-Years assessment of Be and Pb in atmospheric bulk depositions in Cienfuegos (Cuba).

10-years records of monthly bulk atmospheric fluxes of Be and Pb (wet + dry, n = 119 samples) at a coastal station in Cienfuegos (Cuba) between 2010 and 2019 were reported and assessed in function of their temporal variability and meteorological influence. Fluxes of Be and Pb ranged from 120 to 15617 and from 29 to 911 mBq m day, respectively. Both radionuclides exhibited a similar seasonal trend with highest values during wet months and minimum values during dry months.

Application of the Monte Carlo efficiency transfer method to an HPGe detector with the purpose of environmental samples measurement.

Monte Carlo efficiency transfer method was used to determine the full energy peak efficiency of a coaxial n-type HPGe detector. The efficiencies calibration curves for three Certificate Reference Materials were determined by efficiency transfer using a (152)Eu reference source. The efficiency values obtained after efficiency transfer were used to calculate the activity concentration of the radionuclides detected in the three materials, which were measured in a low-background gamma spectrometry system.
