A comparative study of alternative methods for 210Pb determination in environmental samples
Cuesta Beltrán, Estefanía; Barba Lobo, Alejandro; Lozano Bermejo, Rafael Luis
; Gutiérrez de San Miguel Herrera, Enrique; Mosqueda Peña, Fernando; Bolívar Raya, Juan Pedro (Elsevier, 2021)
The accurate determination of the levels of 210Pb in environmental samples (e.g. atmospheric aerosols, waters, soils, biota, etc.) is essential due to its multiple applications in geochronology, radiation protection, ... -
A general methodology to determine natural radionuclides by well-type HPGe detectors
Barba Lobo, Alejandro; San Miguel, E. G.; Lozano Bermejo, Rafael Luis; Bolívar Raya, Juan Pedro (Elsevier, 2021)
This work aims to determine natural radionuclides (210Pb, 228,226Ra, 234,228Th and 40K) in NORM samples by well-type HPGe detectors because they are of vital importance in studies on environmental samples. For this, a novel ... -
A new efficiency calibration methodology for different atmospheric filter geometries by using coaxial Ge detectors
Barba Lobo, Alejandro; Bolívar Raya, Juan Pedro (Springer Science and Business Media LLC, 2023)
The study of the different pollutants present in atmospheric aerosols such as trace elements and radionuclides is essential to assess the air quality. To analyze the particulate matter (PM), atmospheric filters with different ... -
A practical and general methodology for efficiency calibration of coaxial Ge detectors
Barba Lobo, Alejandro; Bolívar Raya, Juan Pedro (Elsevier, 2022-05-06)
The correct determination of artificial and natural radionuclides like 152Eu, 137,134Cs, 60,57Co, etc., and 234,228Th, 228,226Ra, 210Pb and 40K, respectively, is essential for many environmental science fields. For this, ... -
A Practical Procedure to Determine Natural Radionuclides in Solid Materials from Mining
There are many regulations related to the radiological control of NORMs (Naturally Occurring Radioactive Materials) in activities such as mining, industry, etc. Consequently, it is necessary to apply fast and accurate ... -
A simple and precise methodology to determine particulate matter mass in atmospheric filters; validation and application cases
Barba Lobo, Alejandro; Gutiérrez Álvarez, Isidoro; Adame Carnero, José Antonio; Bolívar Raya, Juan Pedro (Elsevier, 2022-11-01)
In the past decades, particulate matter (PM) measurements have been used extensively in atmospheric sciences, as it allows studying the evolution of tracers for different atmospheric processes and the effects of atmospheric ... -
An upgraded lab-based method to determine natural γ-ray emitters in NORM samples by using Ge detectors
Barba Lobo, Alejandro; Mosqueda Peña, Fernando; Bolívar Raya, Juan Pedro (Elsevier, 2021-09-11)
The regulation existing on NORM activities requires the accurate and quick measurement of natural radionuclides in a wide range of matrices by gamma spectrometry. The aim of this work has been to develop a comprehensive ...
