The use of total diet study for determination of natural radionuclides in foods of a high background radiation area
2022 - ROSA, MYCHELLE M.L.; MAIHARA, VERA A.; TADDEI, MARIA H.T.; CHEBERLE, LUAN T.V.; AVEGLIANO, ROSEANE P.; SILVA, PAULO S.C.
The activity concentrations of 40K, 210Pb, 210Po, 226Ra, 228Ra, 228Th, 230Th, 232Th, 234U, and 238U were determined in 82 food samples, grouped into 20 food groups according to the Brazilian Total Diet, which reflects the dietary habits of a population, for the rural and urban areas of Poços de Caldas city, a High Background Radiation Area. The highest activity concentration found in the food samples was due to 40K being present in all types of food. Among the other radionuclides, high activity concentrations were found for 210Pb in beans and salt, 210Po in fish, 226Ra and 228Ra in nuts and seeds. The main food groups that contributed most to the effective dose, in urban and rural regions, were beans and beverages. The effective doses, due to the ingestion of the analysed food groups, were of 0.44 and 0.60 mSv y−1 and the lifetime cancer risks were 1.6 × 10−3 and 2.3 × 10−3 for the urban and rural Poços de Caldas population, respectively.
Radionuclides of natural origin in food and water from a high background radiation area in south-eastern Brazil

Food consumption is one of the main entry routes of radionuclides into the human body. Concentrations of radionuclides of natural origin vary according to several factors such as local geology, climate and agricultural practices. High background radiation areas have attracted much interest from a radiation protection point of view. The Poços de Caldas Plateau is located in south-eastern Brazil and is regarded as a high background radiation area. The situation of the resident population in the region of Poços de Caldas is of special interest for public health surveillance. The activity concentrations of radionuclides of natural origin in 19 groups of food and drinking water were determined. These radionuclides were quantified using gamma spectrometry, ultra low level alpha and beta total counting, and alpha spectrometry, after group preparation and/or radiochemical separations. The results of this study showed that the food groups analysed give rise to a low effective ingestion dose. Calculations were performed using the total radionuclide concentration in each food group, the mass consumed per day by each population group, the total time considered, and the dose intake of each radionuclide. The average annual effective dose received by members of the urban population on the Poços de Caldas plateau was 0.555 mSv.
Neutron activation analysis applied to nutritional and foodstuff studies at IPEN-CNEN/SP

Instrumental Neutron Activation Analysis, INAA, has been successfully used on a regularly basis in several areas of nutrition and foodstuffs. INAA has become an important and useful research tool due to the methodology’s advantages. These include high accuracy, small quantities of samples and no chemical treatment. This technique allows the determination of important elements directly related to human health. In this paper some studies in the area of nutrition which had been carried out at the Neutron Activation Laboratory of IPEN/CNEN-SP are presented: Brazilian Total Diet Studies, trace elements in maternal milk, baby foods, edible mushrooms and wine samples. Total Diet Study (TDS) is considered as the most adequate study to assess the dietary intakes of nutrients of a population. TDS is based in assessment of groups of food, represented by a Food List, which reflects the food consumption of the population. Three Brazilian TDS have been carried out: 2 TDS of the São Paulo city and one of the Poãos de Caldas city, region that is considered as a high background radioactive area, HBA.Deficiency of minor and trace elements can lead to various disorders in the early stages of child development. The essential element level in thirty human colostrum samples from mothers of pre-term and term newborns were studied by INAA.Eating habits are important determinants of health conditions during childhood. Commercial infant food is an important part of the diet for many babies. Inadequate complementary feeding is a major cause of high rates of malnutrition throughout the world. Essential elements: Ca, Cl, Co, Cr, Fe K, Mg, Mn, Na, Se and Zn were also determined in 27 commercial infant food samples by INAA. Mushrooms and algae are excellent nutritional sources since they provide proteins, fibers and mineral. They have also been the focus of medical research. In Brazil these kind of foods are not consumed in large quantities by the general population since people know little about their nutritional and medicinal benefits. Hence, the study of mushrooms and algae intends to contribute to a better understanding of their essential element contents, which are currently commercialized in São Paulo state. Trace elements are good indicators of the origin of wines. Three procedures of wine sample preparation (freeze-drying, evaporation and dry-ashing) to determine essential elements by INAA.
Essential element contents in food groups from the second Brazilian total diet study
2016 - AMBROGI, JESSICA B.; AVEGLIANO, ROSEANE P.; MAIHARA, VERA A.
Total diet study (TDS) has been considered as one of the most appropriate approaches to estimate dietary exposure of essential elements. This paper presents preliminary results of concentrations and average dietary daily intakes of Ca, Co, Cr, Fe, K, Na, Se and Zn from the 2nd Brazilian TDS. Nineteen groups from a Food List which represents the daily intake of the population from the Brazilian southeastern region were analyzed by instrumental neutron activation analysis. The dietary daily intake values for Ca (641 mg), Fe (19.6 mg), K (2738 mg), Na (2466 mg), Se (56.4 lg), and Zn (15.3 mg) were higher than the 1st Brazilian TDS.
