I am looking for collaboration on natural radioactivity measurement and environmental impact
Hi! we have an HPGe detector, what kind of samples do you want analyze?
Hi Naima,
Please, find the attached link. The group it refers to is a univeristy-based, research and comercial radioanalytical laboratory with the ablity to analyse a range of alpha/beta and gamma emitters as well as the elemental analysis by XRF and ICP-MS.
Kind regards,
Pawel

about the measurement of activity concentrations of primordial (238U, 232Th, 226Ra and 40K) and anthropogenic (137Cs) radionuclide's and gamma dose rate in environmental samples using HPGe and NaI (Tl) dedector.
Natural radioactivity in soil is mainly due to 238U, 40K, 232Th and 226Ra, which causes external and internal radiological hazards due to emission of gamma rays and inhalation of radon ant its daughters (UNSCEAR, 1988). Measurement of external gamma dose due to terrestrial sources is necessary not only due to its contributions to the collective dose but also due to variations of the individual dose related to the pathway. These doses strongly depends on the concentrations of 238U, 232Th, their progenies and 40K, presents in rocks and soil, which in turns depends upon the geology of the regions
Professor Naiima Armani
Many labs in the world will have the ability to analyse materials for a number of different radionuclides of interest to you. A strategy would be needed on your part to plan on the basis of objectives - such as research, national screening surveys, mitigation, regulatory development, compliance demonstration, etc.
Considering the ICRP and WHO indications, you might also be interested in some measurements on radon and thoron exhalation characteristics of the building materials, along with other U and Th series radioisotopes.
Regarding gamma spectroscopy, our company (Safe Radiation, Australia) has switched from the use of standard HPGe to BEGe (broad energy high purity germanium) systems. BEGe's should enable coverage of low to high energy gamma rays with comparable efficiency on smaller amounts of samples.

My colleagues and I will be more than happy to collaborate with you.
Hi,
NORM and TENORM are my first lines of research.
How can I help you? If necessary, you can contact me on: [email protected]
Best regards,
Aquino.
