“…Natural radionuclides entering the food chain are mostly derived from the soil and, as a result, variation in soil radionuclide content is a prime source of geographic variability. Plant uptake also varies from species to species; hence the intake of different food products forms a secondary source of variability (McDonald et al 1999;Fernandez et al 2004;Hernandez et al 2004).…”

Ingestion of radionuclides and heavy metals through drinking water and food intake represents one of the important pathways for long-term health considerations. Milk and milk products are main constituents of the daily diet. Radionuclides and heavy metals can be apprehended in the ecosystem of the East Singhbhum region which is known for its viable grades of uranium, copper and other minerals. For the risk assessment studies, samples of milk were collected from twelve villages around Bagjata mining area and analysed for U(nat), 226Ra, 230Th, 210Po, Fe, Mn, Zn, Pb, Cu and Ni. Analysis of the results of the study reveals that the geometric mean of U(nat), 226Ra, 230Th and 210Po was 0.021, 0.24, 0.23 and 1.08 Bq l(-1), respectively. The ingestion dose was calculated to be 12.34 μSvY(-1) which is reflecting the natural background dose via the route of ingestion, and much below the 1 mSv limit set in the new ICRP recommendations. The excess lifetime cancer risk was estimated to be 1.72×10(-4) which is within the acceptable excess individual lifetime cancer risk value of 1×10(-4). The geometric mean of Fe, Mn, Zn, Cu and Ni was 4.91, 0.29, 4.77, 0.56 and 0.48 mgl(-1), respectively; whereas the daily intake was computed to be 0.44, 0.03, 0.43, 0.05 and 0.04 mg/day, respectively. Pb was not detected in any of the samples. The hazard quotient revealed that the intake of the heavy metals through the ingestion of milk does not pose any apparent threat to the local people as none of the HQ of the heavy metals exceeds the limit of 1.

“…One essential feature of soil is the ability to retain and accumulate for long time elements and radionuclides coming from the outside. Therefore, for years, a contaminated soil becomes a source through which radionuclides, trace elements and heavy metals enter agricultural products and subsequently enter the food chain from the soil by plant root uptake (Mc Donald et al, 1999;Breuninger et al, 2002;Hernandez et al, 2004). The long established tin mining operation in Jos plateau may have directly or indirectly affected the concentration of trace elements, heavy metal and radionuclide in food crops planted around these areas.…”

Some crops of important nutritive requirements have been collected from farmlands located in Bitsichi an old tin mining town in north central region of Nigeria. The food crops were analyzed in order to determine trace element concentrations level using Neutron Activation Analysis (NAA). The activity concentrations due to natural radionuclides in the food samples and soil samples collected within the root zone of the crops were also determined using gamma-ray spectrometry (GRS Th. Results of activity concentration levels of the radionuclides obtained in similar crops collected for control measurements were found to be very low compared to those from the study area. The effective dose due to intake of the food crops considered in the study area was estimated based on the measured activity concentrations of 226 Ra and 232 Th in the food crops. It was found to vary between 0.01 mSv y -1 (Acha) and 1.35 mSv y -1 (Cassava) with a cumulative total dose estimated as 2.5 mSv y -1 . The mining activities in the area are seen to have influenced the concentration of these trace elements and radionuclides in the food crops. However, they are seen not to pose any serious internal health burden due to ingestion given the realities of food choice by individuals in the study area.Keywords: food crops / trace elements / radioactivity / ingestion dose / Jos-plateau / Nigeria RÉSUMÉ Éléments traces et mesures de la radioactivité dans quelques récoltes vivrières terrestres du plateau de Jos dans le centre-nord du Nigéria. Quelques récoltes d'aliments importants ont été effectuées dans des champs situés à Bitsichi, une ville minière d'étain dans la région nord central du Nigéria. Les récoltes vivrières ont été analysées afin de déterminer le niveau de concentration d'oligoélément en utilisant l'analyse par activation neutronique (AAN). Les concentrations de radioactivité des radionucléides naturels dans les échantillons alimentaires et des échantillons de sol rassemblés dans la zone des récoltes ont été également déterminées par spectrométrie gamma (GRS). Les résultats d'activation neutronique ont montré que la concentration la plus élevée parmi les éléments

“…Thus, as humans ingest both eggs and poultry meat, it is expedient to monitor the radiation levels in poultry feedstuff since a part of the amount of radionuclides in the feed which animals ingest could possibly be transferred to humans via the radionuclide pathway in the food chain (Mc Donald et al, 1999;Breuninger et al, 2002;Hernandez et al, 2004).…”
