Simultaneous determination of gross alpha, gross beta and ²²⁶Ra in natural water by liquid scintillation counting.
The determination of gross alpha, gross beta and (226)Ra activity in natural waters is useful in a wide range of environmental studies. Furthermore, gross alpha and gross beta parameters are included in international legislation on the quality of drinking water [Council Directive 98/83/EC]. In this work, a low-background liquid scintillation counter (Wallac, Quantulus 1220) was used to simultan...
متن کاملNatural Radioactivity Concentrations and Dose Assessment in Shore Sediments along the Coast of Greater Accra, Ghana
Radioactivity concentration of Naturally Occurring Radioactive Materials (NORMs) in shore sediments (samples) collected along the coast of Accra were analyzed using a gamma spectrometry with a high purity germanium detector. The specific activity concentrations range from 8.60 Bqkg to 61.01 Bqkg with a mean of 29.78 Bqkg for K, 0.62 Bqkg to 148.80 Bqkg with a mean of 22.04 Bqkg for Ra and 0.17 ...
متن کاملAnalysis of gross alpha, gross beta activities and beryllium- 7 concentrations in surface air: their variation and statistical prediction model
Background: Measurement of gross , gross activities, and cosmogenic beryllium-7 (7Be) concentrations were made both daily and weekly during the years 2001- 2004 from samples of atmospheric aerosols filtered from the air at Tehran Nuclear Research Center (35 41' N) and Zahedan (28 29' N). Materials and Methods: Weekly aerosol samples were collected with the high-volume air samplers on cellul...
متن کاملMyiasis in Dogs in the Greater Accra Region of Ghana.
Myiasis is the infestation of tissues of live vertebrate animals and humans with dipterous larvae. In sub-Saharan Africa, Cordylobia anthropohaga and Cordylobia rodhaini are known to be responsible for cutaneous myiasis in animals and humans. Human cases of myiasis, purportedly acquired in Ghana but diagnosed in other countries, have been reported; however, published data on its occurrence in a...
متن کاملNatural radioactivity and heavy metal distribution in reservoirs in Ghana
The present paper has determined the radioactivity concentrations, which are due to natural occurrence of radionuclides along with heavy metal concentration in water, sediment, and fish from 2 reservoirs in Ghana. Heavy metal concentrations in all samples were generally within the WHO safe limits with the average activity concentrations of 238U, 232Th, and 40K in water being respectively 0.42±0...
