“…The 40 K concentration obtained is similar to what was obtained in Egypt (Harb et al, 2010) but higher for 226 Ra and 232 Th. In Brazil, a higher concentration of 40 K was reported in poultry feeds (Filho et al, 2016). Similarly, a higher concentration of 40 K than the present study was reported in Benue and Kaduna states, Nigeria (Ageda et al, 2017).…”

“…To this end, supplementary minerals were added to stimulate growth (Scheibel et al, 2006). Also, some feed produced from plants and animal sources (organic base) to give complete nutrition for the birds contains organic matter (Filho et al, 2016). These feeds may also contain natural radionuclides that may contaminate the poultry feeds (Ageda et al, 2017).…”

“…Many researchers had carried out researches in many parts of the world on poultry feeds and chicken meats. In Brazil, Filho et al, 2016, revealed a high level of 40 K concentration in samples of poultry rations and dicalcium phosphate (DCP) used for cattle feed. Ageda et al, (2017) investigated the natural radionuclide levels in some Nigerian made poultry feedstuff and revealed that Nigerian poultry feeds have a relatively higher concentration of 226 Ra and 232 Th.…”

Poultry farming is a highly profitable and not capital intensive agricultural project. It is becoming one of the highest investments in agriculture in Nigeria. The proliferation of self -produced feeds by the Farmers with the addition of some minerals to stimulate growth could elevate the levels of radionuclides in feeds. This, therefore, calls for the determination of the health effects from the consumption of these chicken meats and organs. 10 samples of broilers and 30 feed samples (10 each of Starter, Grower, and Finisher feeds used in feeding the chicken) were used; collected from five selected poultry- farms in Lagos State, Nigeria, and analyzed using spectrometry analysis with NaI (Tl). The results obtained showed that concentrations of 40K, 232Th, and 226Ra were 49.0±25.8, 24.9 ±12.2, and 32.9 ±16.2 Bqkg-1 respectively, in chicken meats. In the feeds, their values were below the UNSCEAR recommendation. The annual effective doses in chicken meats and organs were lower than the 70µSv/yr limit. The cancer risk was within the recommended limit, and the internal hazard indices were below unity. The mean values of the transfer coefficient (TC) were also below 1 for 40K, higher than unity for 226Ra in Finisher feeds, and 232Th in Starter feeds. The starter and finisher feeds were moderately contaminated. So, feeding chicken with these feeds may expose the consumers to the danger of over-exposure to 226Ra and 232Th.

“…Porém este processo não garante a retirada dos radionuclídeos naturais, como pode ser observado na Tabela 2, onde as concentrações de 228 Ra e 226 Ra variaram significativamente. A concentração média de 228 Ra e 226 Ra em amostras de fosfato bicalcico produzido no Brasil variou de 4.200 a 8.300 mBq.kg -1 na matéria seca, respectivamente [22]. Esses valores estão na mesma faixa de variação daqueles apresentados na Tabela 2.…”

No estado de Pernambuco, os produtos industrializados de origem vegetal e mineral são intensamente utilizados na alimentação de vacas leiteiras. Porém, dependendo da origem, esses alimentos podem conter quantidades significativas de radionuclídeos naturais, principalmente 228 Ra e 226 Ra que estão distribuídos na crosta terrestre em quantidades variáveis. Os alimentos de origem vegetal podem conter quantidades significativas de 228 Ra e 226 Ra, pois dependendo do local onde a planta foi cultivada, esses radionuclídeos são eficientemente absorvidos pelas raízes. No caso dos alimentos minerais, grande parte deles são oriundos de rochas fosfáticas que são predominantemente ricas em radionuclídeos naturais, inclusive 228 Ra e 226 Ra. O objetivo desse trabalho foi determinar as concentrações de 228 Ra e 226 Ra em alimentos industrializados consumidos por vacas leiteiras no estado de Pernambuco. As concentrações de 228 Ra nas amostras de alimentos de origem vegetal variaram de 2.738 a 22.266 mBq.kg -1 na matéria seca, e de 2.582 a 63.000 mBq.kg -1 na matéria seca nas amostras de alimentos de origem mineral (fosfato bicalcico). No caso do 226 Ra, as concentrações variaram de 246 a 2.600 mBq.kg -1 na matéria seca para as amostras de alimentos de origem vegetal, e de 1.300 a 7.800 mBq.kg -1 na matéria seca, para as amostras de alimentos de origem mineral (fosfato bicalcico).

Abstract: K activity has reached hundreds of Becquerel in feed samples, it should not represent a risk to human health, not even to animals, since potassium is an essential mineral to living organisms.
