Radioactivity Levels and Soil-to-Plant Transfer Factor of Natural Radionuclides from Protectorate Area in Aswan, Egypt

Abstract

The aim of this study is to determine the transfer factor soil-to-plant and to assess the concentration level of natural and artificial radionuclide (238 U, 226 Ra, 228 Ra, 232 Th, 40 K and 137 Cs) in samples from Saluga and Ghazal Protectorate area in Aswan, Egypt, by using High Pure Germanium detector (HPGe) Environmental Radioactivity Measurements Labrotary in faculty of science Qena. Reported values for natural radionuclides ranged from 8.81

Estimation of radionuclides concentration and average annual committed effective dose due to ingestion for some selected medicinal plants of South India

“…In most places on earth, natural radioactivity varies only within relatively narrow limits, whereas in some other localities significant deviations have been observed. All these radionuclides present in the environment are taken up by the plants through the metabolic process and are present in varied concentrations in different parts of the plants (Golmakani, Moghaddam, & Hosseini, 2008;Harb, E-Kamel, E-Mageed, Abbady, & Rashed, 2014;Karunakara, 1997;Kannan, Rajan, Iyengar, & Ramesh, 2002;Lordford, Emmanuel, Cyril, & Alfred, 2013;Patra, Jaison, Baburajan, & Hegde, 2008).…”

Transfer of Natural Radionuclides from Soil to Plants and Grass in the Western North of West Bank Environment- Palestine

“…In recent years, examination of radioactive isotopes in the environment and their role for living things of our planet has attracted growing attention, increasing radionuclide concentration in the environment and threatening living organisms by entering the food chain from plants to animals and, finally, to man [6]. The uptake of radionuclides by plants from the soil is normally described by the transfer factor (TF) [7]. The plants take in deposited radionuclides from soil commonly expressed as soil-to-plant transfer factor (TF); TF is widely used for calculating radiological human dose via the ingestion pathway.…”

“…Natural environmental radioactivity arises mainly from primordial radionuclides, such as 40 K, and the radionuclides from the 232 Th and 238 U series, and their decay products are considered to be the main contributor to internal radiation dose. Several studies on the transfer of natural radionuclide's from soil to plant have been carried out in different regions in the world [5,[7][8][11][12][13]. However, there seems to be no data on the transfer of natural radionuclide's from soil to plant in the environment of Palestine.…”

Transfer factors of 40K, 226Ra, 232Th from soil to different types of local vegetables, radiation hazard indices and their annual doses

“…meat, eggs and milk, make a big contribution, whereas, in Asian and south American, crops including cereals and vegetables are the main contributions. According to the Iraqi habits, they consume large amounts of vegetables (in kg y -1 ), including tomato (50), cucumber (28), eggplant (20), green pepper (10), okra (15), squash (20) water melon (28) and onion (28). C F (Sv Bq -1 )…”

“…The activity concentrations were determined from measuring their respective decay daughters 214 Bi at 609 keV (I = 45 %) and 1,765 keV (I = 15.8 %) for 226 Ra and 208 Tl at 2,615 keV (I = 100 %) for the 232 Th-series while 40 K activity concentration was determined directly from its emission at 1,460 keV (I = 11 %). The TF was calculated for each radionuclide using the following formula [7,14,20]:…”
