摘要:Abstract(#br)Correlations between sediment contaminants like heavy metals or organic micro-compounds and natural or anthropogenic radionuclides ( 40 K, 238 U, 232 Th, 137 Cs) facilitates in situ mapping of the contaminated sediment using gamma-ray detectors. These maps can be ...

摘要:Abstract(#br)The soil's gamma radiometric signal is known to be a crucial indicator of the heterogeneity of soil properties, most likely directly related to the mineralogy and geochemistry of the parent material. However, fine-resolution radiometric data sourced from geophysical...

摘要:... This novel in situ method lends itself to the mapping of activity concentrations in environments that exhibit systematic changes in the vertical activity distribution. The robustness of this approach has been demonstrated in a salt marsh environment on the Solway coast, SW...

摘要:... The radiometric maps must take into consideration gamma doses from soils as well as from underlying rocks in the first metre of ground profile. This is of crucial importance especially for carbonate terrains, where the differences between natural radionuclide concentrations i...

摘要:Abstract. Recent developments in in situ γ ray spectrometry offer a new approach to measuring the activity of radionuclides such as 137Cs and 40K in soils, and thus estimating erosion or deposition rates and field moist bulk density ( ρm ). S...

摘要:Correlations between sediment contaminants like heavy metals or organic micro-compounds and natural or anthropogenic radionuclides ((40)K, (238)U, (232)Th, (137)Cs) facilitates in situ mapping of the contaminated sediment using gamma-ray detectors. These maps can be made quickly ...

摘要:... This paper pretends to show the adequability of using a fast and reasonably inexpensive survey technique such as in situ gamma-ray portable detectors, to access the radiometric response of the systems in study by providing the radiometric mapping of the areas. The existence o...

摘要:... Mapping of the radiation fields in urban areas allows a detailed assessment of exposure pathways for the people who live and work there, as well as locating discrete sources of activity that may warrant removal to mitigate dose to the general public. These areas also present ...
