Preliminary studies on 226Ra, 228Ra, 228Th and 40K concentrations in foodstuffs consumed by inhabitants of Accra metropolitan area, Ghana

Determination of Natural Radioactivity and Radiological Hazards of 226Ra, 232Th, and 40K in the Grains Available at Penang Markets, Malaysia, Using High-purity Germanium Detector

“…The alpha radiation producing from the grain is estimated through alpha index should be less than 1 and is calculated according to the equation (Awudu et al, 2012) and average value of Iα is 0.360 Bq.kg −1 that is <1, as shown in Table III, which is in agreement with the study of Gordana et al, 2015, Fig. 2.…”

“…These natural radioactive sources are the largest contributor of the radiation doses received by humanity (Abdulaziz et al, 2013). Naturally occurring potassium 40 K is present virtually in all foodstuff as primary constituent of cellular material (Abdulaziz et al, 2013;Rohit et al, 2014;Awudu et al, 2012;Cumhur and Mahmut, 2013). Radionuclides can enter the human body through inhalation and ingestion.…”

“…The primary purpose of this study is to determine the activity concentration levels of 226 Ra,232 Th, and 40 K in the different types of grain that are available in Penang markets, Malaysia, to ensure that food safety is not compromised and the effective doses due to ingestions are within the specified safety limits. Several studies have been performed in different countries to determine the radionuclide concentration in different food samples and dose assessment from consumption of that foodstuff by the population (Awudu et al, 2012). As grain and its products are the main component of daily serving such as breads, rice, and pasta, it is considered as a staple food.…”

Gamma Radiation Measurements of Naturally Occurring Radioactive in Igneous Rocks and Its Radiological Complications

“…AEDE mSv y D nGy h 8760 h y 0.7 Sv Gy 0.2 10 [19]. However, the 40 K mean value of this study is still more below the rigid control 100,000 Bq•kg −1 as given by IAEA [20].…”

Radiological hazard of coffee to humans: a comparative study of Arabian and Turkish coffees

“…Some naturally occurring radioisotopes and other elements present in soil are drawn into the roots of plants via ion channels or specific transporters (Sugiyama et al, 2009;Jibiri et al, 2016). Their distribution throughout the plant tissues depends on their chemical characteristics and several parameters of soil and the plants themselves (Awudu, 2012). Several studies have been performed to determine the concentrations of elements in various types of coffee and to estimate whether these concentrations contribute to toxicity (Szymczycha-Madeja et al, 2014;Welna et al, 2014;Jarošová et al, 2014;Zaidi et al, 2005).…”
