Mapping environmental radioactivity from field gamma-ray spectrometry is a valuable tool for understanding and interpreting pedological control of naturally occurring radioactivity. Soil properties and water content affect the behaviour of natural radioactivity. The main aim of the study were to explore and map the activity of three naturally occurring radionuclides (Th, U, K) in an olive orcha...
the existence of a high natural radiation area in the northern part of iran (ramsar) is proved. ra 226 in soil is measured. the results are: minimum 23.5 pci/g and maximum 999 pci/g soil. environmental radioactivity is from 0.1 to 5 mr/h.
Our recent attempt to determine ultratrace-level 236U and 233U in small-volume seawater samples was challenged by high unstable procedure blanks our environmental radioactivity laboratory, w...
introduction artificial and natural radionuclides are found in diverse environmental compartments, such as water, soil, rocks, vegetables, animals, and human body tissues. as such, humans and environments are at constant exposure of these radiation types. in this research investigated specific activities of radionuclide and dose assessment of some species of mushrooms. materials and methods in ...
Radioactivity measurements for water, soil, and air have been completed in national international regions. The radioactivity process is randomized occurs naturally by primordial nuclides. Another case hand-made reactions which realized artificial reactions. high rate of the total dose radiation, whichever exposed to humans, originates as Natural Radioactivity. In this case, environmental are im...
