[Ab] Resumo:Food samples are collected nationwide from January 2016 to February 2017 and their contents of artificial radionuclides are measured to address the growing concerns regarding the radioactive contamination of food products in Korea. Specifically, 900 food samples are collected for this study and their contents of representative artificial radionuclides Cs, Cs, Pu, and Sr are analyzed. The analysis shows that the activity concentrations of Cs in fish range from minimum detectable activity (MDA) to 340 mBq/kg of fresh weight. The concentration factor (CF) determined for Cs as a measure of its bioavailability is calculated to be ca. 74 and found to be very similar to that (100) recommended by the International Atomic Energy Agency. With an MDA of <0.221 mBq/kg, the results reveal that Pu values in fish are below the MDA. The activity concentrations of Cs and Sr are lower than the MDA in both shellfish and seaweed, while the activity concentrations of Pu in shellfish range from 0.26 to 2.18 mBq/kg, and for seaweed samples range from 2.07 to 3.38 mBq/kg. The atom ratios of Pu/ Pu in shellfish caught at the Korean coast vary from 0.209 to 0.237, with a mean of 0.227. The higher Pu/ Pu atom ratio determined in shellfish is thought to be caused by the plutonium transported from the Pacific Proving Grounds rather than other sources such as the Fukushima nuclear power plant accident. The activity concentrations of Cs in mushrooms are found to vary from 1.0 to 21.4 Bq/kg, with the highest concentrations observed in the Oak (shiitake) and Sarcodon asparatus. Cs is detected in three mushroom specimens collected from Jeju Island and about 3-3.6% of Cs present in the wild mushrooms native to the Jeju Island are introduced as a result of the Fukushima nuclear plant accident. The annual effective doses of Cs received through consumption of mushrooms and fish are 2.0 × 10 mSv yr and 3.9 × 10 mSv yr , and those values are negligible compared to the annual effective doses limit of 1 mSv yr .

[Ab] Resumo:Background: Potatoes are an important component of the human diet. In addition to components which determine the nutrition and dietary values, potato tubers also contain anti-nutritional substances, inter alia radioactive elements. Natural and artifical radionuclides are released to the environment as a result of antropogenic activity, in a controlled or uncontrolled manner, and they are transferred to the human body through the food chain. Objective: The aim of the study was to determine the activity of radioactive cesium 137Cs isotope and potassium content, including the activity of 40K isotope, in new potatoes imported to Poland during the winter period from Mediterranean countries. Material and methods: The study material included new potatoes imported from Cyprus, Egypt and Israel, purchased in the city of Siedlce from the beginning of February to the end of March 2015. The activity of 137Cs and 40K isotopes in potato tubers was determined. Analyses were performed by γ-spectrometric method. Laboratory tests were performed on a total of 18 samples. Based on the activity of 40K isotope, the total potassium content of potato tubers was calculated, with the assumption that 31.00 Bq 40K is equivalent to 1 g potassium. Results: The activity of 137Cs in most tested potato samples was below 0.2 Bq kg-1 (limit of quantification), and in other samles it was from 0.3 Bq kg-1 to 5.4 Bq kg-1. Potatoes of the same variety, originating from the same country, differed in terms of the activity of 137Cs. The highest activity of 137C, determined in potatoes imported from Cyprus, was seven times higher than the lowest value. The activity of 40K changed from 93.3 Bq kg-1 to 259.1 Bq kg-1. The average activity of 40K in potatoes imported from Cyprus, Egypt and Israel was at a similar level. The ratio of the activity of 137Cs determined in the tested potatoes to the activity of 40K changed from 0.00242 to 0.04163. The calculated potassium content in imported new potatoes was on average 4.376 g K kg-1 of the fresh weight of tubers and ranged from 3.010 g K kg-1 to 8.358 g K kg-1. Conclusions: The activity of the 137Cs cesium isotope in imported new potatoes in most tested samples was at a very low level (below the limit of quantification) and in other samples it did not exceed 5.5 Bq kg-1 and posed no threat to human lives. Potatoes originating from the same country differed in terms of the activity of 137Cs. The average activity of 40K in potatoes imported from Cyprus, Egypt and Israel was at a similar level and did not differ from the activity of 40K in domestically produced potatoes. The potassium content in imported new potatoes was determined by the variety.

[Ab] Resumo:The present study was carried out to survey the levels of plutonium isotopes ( Pu) and strontium ( Sr) in domestic seafood in Korea. In current, regulatory authorities have analyzed radionuclides, such as Cs, Cs and I, in domestic and imported food. However, people are concerned about contamination of other radionuclides, such as plutonium and strontium, in food. Furthermore, people who live in Korea have much concern about safety of seafood. Accordingly, in this study, we have investigated the activity concentrations of plutonium and strontium in seafood. For the analysis of plutonium isotopes and strontium, a rapid and reliable method developed from previous study was used. Applicability of the test method was verified by examining recovery, minimum detectable activity (MDA), analytical time, etc. Total 40 seafood samples were analyzed in 2014-2015. As a result, plutonium isotopes ( Pu) and strontium ( Sr) were not detected or below detection limits in seafood. The detection limits of plutonium isotopes and strontium-90 were 0.01 and 1 Bq/kg, respectively.

[Ti] Título:Are dietary reports in a case-control study on thyroid cancer biased by risk perception of Chernobyl fallout?

[Ab] Resumo:BACKGROUND: In retrospective case-control studies performed following nuclear tests or nuclear accidents, individual thyroid radiation dose reconstructions are based on fallout and meteorological data from the residential area, demographic characteristics, and lifestyle as well as dietary information. Collecting the latter is a controversial step, as dietary declarations may be affected by the subjects' beliefs about their risk behavior. This report analyses the potential for such bias in a case-control study performed in eastern France. METHODS: The study included 765 cases of differentiated thyroid carcinoma matched with 831 controls. Risk perceptions and beliefs of cases and controls were compared using Chi tests and differences in dietary reports were analyzed using a two-way ANOVA. RESULTS: In general, atmospheric pollution and living near a nuclear power plant were the two major risks that may influence thyroid cancer occurrence cited by cases and controls. When focusing in particular on the consequences of the Chernobyl accident, cases were more likely to think that the consequences were responsible for thyroid cancer occurrence than controls. Vegetable consumption during the two months after the Chernobyl accident was correlated with the status of subjects, but not to their beliefs. Conversely, consumption of fresh dairy products was not correlated with the status or beliefs of subjects. CONCLUSION: We found no evidence of systematic bias in dietary reports according to the status or beliefs held by subjects about the link between thyroid cancer occurrence and Chernobyl fallout. As such, these dietary reports may be used in further studies involving individual dosimetric reconstructions.

[Ab] Resumo:PURPOSE: This study examined the internal Cs exposure of residents and the Cs present in food products produced in Namie. Whole-body counter (WBC) was used for the measurement of internal exposure per each whole body of examinees. METHODS: The food products which appeared to be used for consumption, were brought by residents and commercially available food items were excluded. Most of them were wild plants or food items produced by residents. Four years of data from April 2012 to March 2013 (fiscal 2012) and April 2015 to March 2016 (Fiscal 2015) were analyzed and studied. RESULTS: The average radioactivity measured by WBC was approximately 5 Bq for Cs-134, and 20 Bq for Cs-137 and the average committed effective dose was approximately 1 µSv. The average for the residents with detectable radioactivity was 25 µSv, and the human health effects are considered to be extremely low risk. However, the radioactivity of the affected individuals showed a higher value than the theoretical attenuation rate. The majority (83.2%) of individuals exhibiting radioactivity were over 50 years old. The number of food products brought in for detection decreased as the study period progressed, but the number of food products with radioactivity had increased. While the items with a higher detection rate of radioactivity included fruits such as citron and persimmon, shiitake mushrooms exhibited the highest radioactivity. Moreover, the radioactivity of seven items in these 10 items decreased from fiscal 2012 to fiscal 2015. Mushrooms had high radioactivity and were produced over a wide area. CONCLUSION: We suggest that the elderly try to enjoy life and eat wild plants in moderation while inspecting food products. Therefore, we will continue to work in raising awareness of radiation and its potential presence in food products and thus the continuing necessity of monitoring radioactivity in food in the future.

[Ab] Resumo:This paper presents a calculator to facilitate assessments of ingestion doses from Aboriginal bush foods. The calculator combines information on traditional diet and land use with radionuclide concentration ratios and ingestion dose coefficients to estimate doses. The calculator was applied to the planned remediation of Ranger uranium mine to derive a set of scaling factors between radionuclide activity concentrations in environmental media and ingestion dose from bush foods. The scaling factors can be used to estimate doses from bush foods once the post-remediation radiological conditions of the mine and surrounding environment are known.

[Ti] Título:Surveys of Food Intake Just after the Nuclear Accident at the Fukushima Daiichi Nuclear Power Station.

[Ab] Resumo:As a result of the nuclear accident at the Fukushima Daiichi nuclear power station (FDNPS) after the Great East Japan Earthquake on March 11, 2011, volatile radionuclides including iodine-131 were released into the environment and contaminated open-field vegetables, raw milk, tap water, etc. It is important for the health care of residents to correctly comprehend the level of their exposure to radioactive substances released following the accident. However, an evaluation of the internal exposure doses of residents of Fukushima Prefecture as a result of the ingestion of foods, which is indicated in the report issued by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR)1 is based on a number of assumptions. For instance, the estimation assumes that foods were ingested as usual, without regard to the places to which residents were evacuated after the accident, the places where food shipment restrictions were imposed, and so forth. The present report aims to improve the accuracy of estimation of the amount of food actually ingested at evacuation areas, in order to reduce as much as possible the level of uncertainty in conventional values estimated directly after the accident, which were in fact values based on conservative assumptions. More concretely, as basic source material to more accurately estimate internal exposure doses from food ingestion, various patterns of evacuation and dietary habits at the time of the accident of the residents of 13 municipalities in Fukushima Prefecture who were evacuated during the period from directly after the accident of March 11, 2011 until the end of March are clarified in this report. From survey results, most of the food that evacuees took immediately after the accident was confirmed to have been sourced from either stockpiles prepared before the accident, or relief supplies from outside of the affected areas. The restriction orders of food supplies such as contaminated vegetables and milk, and tap water intake were implemented within several days after the major release of radionuclides on March 15, 2011. In addition, collapse in supply chains, i.e., damage to distribution facilities, lack of transportation vehicles or electricity, and the closure of retail stores, contributed to a situation where food or supplies contaminated with iodine -131 were not consumed in large quantities in general, even before the food restriction order. Since people consumed tap water and water from other sources before the implementation of restriction orders in affected areas, we surveyed the status of water as a potential route of internal exposure.

[Ti] Título:Ingestion intakes of Cs by the Czech population: Comparison of different approaches.

[Ab] Resumo:Ingestion intakes of Cs of the Czech population were calculated in two different ways - either from the measured activity of Cs in components of food in combination with statistical data about consumption rates or from retention of Cs in the human body obtained by whole body counting or calculated from daily urinary excretion of Cs. Data from the time period since 1986 to 2015 are used. The daily ingestion intake was about 25 Bq d in 1986 and is around 0.1 Bq d at present. Both approaches of ingestion intake calculation have their advantages and disadvantages. Ingestion intake calculated from Cs body content was assumed to be the most accurate as it requires fewer assumptions than the calculation from food consumption. However, calculation of Cs intake from food consumption is an important tool for prediction doses after the release of radionuclides into environment. The best agreement exceeding the intakes from urine measurement 5 times at maximum was achieved when intakes calculated from food also included products from the natural environment. Without this, the ingestion intake could be under-predicted seriously up to 6 times, especially in the longer time after the release of Cs into environment. Ingestion intakes up to 11 Bq d in a group of people with significant consumption of game meat containing elevated activity of Cs activity were included as a special case. Various groups of foodstuffs had varying effects on the total committed effective dose from Cs. Dose estimates for the Czech population from Cs ingestion intake achieved 80 µSv in 1986 and not more than 2 µSv currently and were similar to those incurred by the population of neighbouring countries.

[Ab] Resumo:Among High Level Natural Radiation Areas (HLNRAs) all over the world, the northern coastal city of Ramsar has been considered enormously important. Many studies have measured environmental radioactivity in Ramsar, however, no survey has been undertaken to measure concentrations in the diets of residents. This study determined the Ra activity concentration in the daily diet of people of Ramsar. The samples were chosen from both normal and high level natural radiation areas and based on the daily consumption patterns of residents. About 150 different samples, which all are local and have the highest consumption, were collected during the four seasons. In these samples, after washing and drying and pretreatment, the radionuclide was determined by α-spectrometry. The mean radioactivity concentration of Ra ranged between 5 ± 1 mBq kg wet weight (chino and meat) to 725 ± 480 mBq kg for tea dry leaves. The Ra activity concentrations compared with the reference values of UNSCEAR appear to be higher in leafy vegetables, milk and meat product. Of the total daily dietary Ra exposure for adults in Ramsar, the largest percentage was from eggs. The residents consuming eggs from household chickens may receive an elevated dose in the diet.

[Ab] Resumo:This study, for the first time, presents the results of activity concentration determinations for Cs and K in a high number (21 species, 87 composite samples, and 807 fruiting bodies) of mushrooms of the genus Boletus from across Yunnan in 2011-2014 and Sichuan (Boletus tomentipes) using high-resolution high-purity germanium detector. Activity concentrations of Cs demonstrated some variability and range from <4.4 to 83 ± 3 Bq kg dry biomass in caps and from <3.8 to 37 ± 3 Bq kg dry biomass in stipes, and of K, respectively, from 420 ± 41 to 1300 ± 110 and from 520 ± 61 to 1300 ± 140 Bq kg dry biomass. No significant variations were observed regarding Cs and K activity concentrations among the same Boletus species from different sampling sites. No activity concentrations from Cs were detected in any mushrooms. Internal dose rates estimated were from intake of 1 kg of mushrooms per annum for Cs range for species and regions from around <0.0031 to 0.047 ± 0.003 µSv, while those for K were from around 0.22 ± 0.04 to 1.2 ± 0.1 µSv. The overall intake of Cs was low since low contamination was found in Boletus species.
