“…The net area under the corresponding peaks in the energy spectrum was computed by subtracting counts due to Compton scattering of higher peaks and other background sources from the total area of the peaks. From the net area, the activity concentrations in the samples were obtained using the equation (Jibiri and Bankole, 2006;Jibiri et al, 2007aJibiri et al, , 2007b:…”

“…Majority of these reports attributed these high levels primarily on the influence of tin and its mining activities in the area while the influence of the geological formation of the area was also identified as a factor (Farai and Jibiri, 2000;Jibiri et al, 2007aJibiri et al, , 2007bJibiri and Agomuo, 2007;Ademola, 2008). Presently, no attempt has been made to consider singularly farm soils in relation to radioactivity levels, the effects it portents to the farmers during farming activities based on the fact that the areas under investigation are known for high radiations.…”

“…According to Jibiri et al (2007aJibiri et al ( , 2007b, Jibiri and Agomuo (2007), Alexander and Kidd (2000) and Pasquini and Alexander (2005), heavy applications of different brands of chemical fertilizers and refuse ash were used by local farmers to improve the soil fertility and reclamation initiatives. Mittra et al (2003) reports that one of the possible ways of enhancing productivity of acidic soil is the use of fly ash in appropriate combination with organic matter and chemical fertilizer which would act as soil amendment and source of nutrient supply system.…”

Assessment of external and internal doses due to farming in high background radiation areas in old tin mining localities in Jos-plateau, Nigeria

Farming on soils situated in high background radiation areas can result to enhanced radiation exposure scenarios and pathways to humans. To assess the likely levels of exposures, farm soil samples were collected from different farmlands in three old tin mining localities (Bitsichi, Bukuru and Ropp) in Jos Plateau Nigeria, known for high radiations. The soil samples were analyzed for the activity concentrations of 226 Ra, 232 Th and 40 K, using gamma-ray spectroscopy. The outdoor annual effective dose rates were calculated using the activity concentrations of the radionuclides and were found to vary from 0.07 mSv to 2.02 mSv across the three localities. Considering dust generation from soil tillage and inadvertent ingestion of soil particles, the likely internal radiation hazards were estimated using conservative dust and soil loading factors.

“…Tin mining and processing of by-productheavy minerals from tin mining as contributed a number of natural radionuclides to the environment; this contribution occurs since those minerals, such as heavy mineral sand, monazite, ilmenite, zircon or xenotime, contain natural radioactive elements which co-exist with the tin ore or cassiterite in the ground [3][4][5][6].…”

“…In some parts of the world, population growth and movement, industrial development and food security have resulted in pressure to use agricultural lands containing relatively high levels of radioactivity, for instance in the monazite areas of India and Brazil, and in parts of Iran with 226Ra anomalies where exposures up to tens of mSv, and in extreme cases 100 mSv, occur annually [2] and in many localities of black sand along the Mediterranean coast of Egypt [3][4][5].…”

Current knowledge on the basic radionuclide tolerance indicates that plants may develop mechanisms preventing the damaging effects of radionuclide stress. The radionuclides content was determined in the Mediterranean coastal black sand soil and in the edible portions of the four food crop plant species, viz., Eruca sativa, Lycopersicon esculentum, Pasidium guajava and Mangifera indica. Biochemical and nutritional constituents were assessed to elucidate the possible effect of radionuclides on the edible portions of the plants. The ability of the four study plant species to accumulate Uranium and Thorium in their edible portions from the coastal black sand soil is higher than that absorbed from the inland agricultural soils. The nutritional constituents were affected by the high concentrations of Uranium and Thorium in the plant tissues. The total protein, moisture content, total phenolic compounds, total chlorophyll, total carotenoids, β-Carotene and Lycopene were positively correlated with Uranium and Thorium concentrations in the plant tissues, while the mineral content, vitamin C and total flavonoids were suppressed by high concentrations of Uranium and Thorium in the plant tissues. The fluctuations in the biochemical or nutritional constituents of the plant edible portions are considered an important defense mechanism to control the redox state of the cells accumulating radionuclides with high levels.
