  • abstract

Interviews with questionnaires are often employed to provide information that may be used for exposure assessment, although the reliability of such information is largely unknown. In this work, the consistency of individual behavior and dietary data collected by means of personal interviews during two study screenings was evaluated. Data were collected for a cohort of about 11,000 persons exposed to I in childhood and adolescence shortly after the Chernobyl accident. The best recollection was found for residential history, milk consumption patterns, and, to a lesser degree, stable iodine administration, while reproducibility of responses about consumption of milk products and leafy vegetables was poor. Consistency of information reported during the personal interviews by the study subjects younger than 10 y at the time of the accident was somewhat lower than for the subjects aged 10-18 y. The authors found slightly better reproducibility of responses for female study subjects than for male subjects and when the time span between two interviews was shorter. In the majority of instances, the best consistency in responses was observed when the mother was interviewed during both screenings rather than the subject. Information that was collected during two personal interviews was used to calculate two sets of thyroid doses due to I intakes. This study shows that, because dose-related measurements are available for all study subjects, the quality of individual behavior and dietary data has, in general, a small influence on the results of the retrospective dose assessment. For studies in which dose-related measurements are not available for all study subjects and only modeling is used for dose reconstruction, high quality individual behavior and dietary data for the study subjects are required to provide realistic and reliable dose estimates.

LEBEL LK, DICKSON RS, GLOWA GA – Radioiodine in the atmosphere after the Fukushima Daiichi nuclear accident. - Journal of environmental radioactivity, 01/2016, 151, Part1, 82-93.

  • abstract

About 160 PBq of (131)I was released into the atmosphere during the accident at the Fukushima Dai-ichi Nuclear Power Plant. The chemistry of radioiodine is complicated, and it can be released in several different forms. In addition, the different physical forms, like molecular iodine, aerosol-form iodine, or organic iodine, would have all behaved differently once in the atmosphere, and would have been removed at different rates. These releases were detected by monitoring stations throughout Japan, and from these measurements, key insightscan be made about the different chemical forms that were released, as well as the persistence of each in the environment.

  • abstract

Tritium is the radioactive isotope of hydrogen. It can be integrated into most biological molecules. Even though its radiotoxicity is weak, the effects of tritium can be increased following concentration in critical compartments of living organisms. For a better understanding of tritium circulation in the environment and to highlight transfer constants between compartments, we studied the tritiation of different agricultural matrices chronically exposed to tritium. Milk is one of the most frequently monitored foodstuffs in the vicinity of points known for chronic release of radionuclides firstly because dairy products find their way into most homes but also because it integrates deposition over large areas at a local scale. It is a food which contains all the main nutrients, especially proteins, carbohydrates and lipids. We thus studied the tritium levels of milk in chronic exposure conditions by comparing the tritiation of the main hydrogenated components of milk, first, component by component, then, sample by sample. Significant correlations were found between the specific activities of drinking water and free water of milk as well as between the tritium levels of cattle feed dry matter and of the main organic components of milk. Our findings stress the importance of the metabolism on the distribution of tritium in the different compartments. Overall, dilution of hydrogen in the environmental compartments was found to play an important role dimming possible isotopic effects even in a food chain chronically exposed to tritium.

MEULEPAS JM, RONCKERS CM, MERKS J et al. – Confounding of the association between radiation exposure from ct scans and risk of leukemia and brain tumors by cancer susceptibility syndromes. - Cancer epidemiology biomarkers and prevention, 01/2016, 23, 1, 114-126.

  • abstract

BACKGROUND: Recent studies linking radiation exposure from pediatric computed tomography (CT) to increased risks of leukemia and brain tumors lacked data to control for cancer susceptibility syndromes (CSS). These syndromes might be confounders because they are associated with an increased cancer risk and may increase the likelihood of CT scans performed in children.

METHODS: We identify CSS predisposing to leukemia and brain tumors through a systematic literature search and summarize prevalence and risk estimates. Because there is virtually no empirical evidence in published literature on patterns of CT use for most types of CSS, we estimate confounding bias of relative risks (RR) for categories of radiation exposure based on expert opinion about the current and previous patterns of CT scans among CSS patients.

RESULTS: We estimate that radiation-related RRs for leukemia are not meaningfully confounded by Down syndrome, Noonan syndrome, or other CSS. In contrast, RRs for brain tumors may be overestimated due to confounding by tuberous sclerosis complex (TSC) while von Hippel-Lindau disease, neurofibromatosis type 1, or other CSS do not meaningfully confound. Empirical data on the use of CT scans among CSS patients are urgently needed.

CONCLUSIONS: Our assessment indicates that associations with leukemia reported in previous studies are unlikely to be substantially confounded by unmeasured CSS, whereas brain tumor risks might have been overestimated due to confounding by TSC.

IMPACT: Future studies should identify TSC patients in order to avoid overestimation of brain tumor risks due to radiation exposure from CT scans.

  • abstract

OBJECTIVES: Although fluoroscopically guided interventional procedures (FGIP) have provided major advances in the treatment of various common diseases, radiation exposures associated with these procedures may cause adverse health effects in workers. We assess risk of circulatory disease incidence and mortality in medical radiation workers performing FGIP.

METHODS: A US nationwide prospective cohort study of 90 957 radiologic technologists who completed a cohort survey during 1994-1998 was followed until completion of a subsequent survey during 2003-2005 for circulatory disease incidence, or until 31 December 2008 for mortality. Incidence analyses were restricted to the 63 482 technologists who completed both the second survey (1994-1998) and the third survey (2003-2005). Cox proportional hazards models were used to assess adjusted HR and 95% CIs for mortality from all causes, all circulatory diseases, all heart diseases, ischaemic heart disease, stroke, acute myocardial infarction and hypertension in participants who reported ever performing FGIP compared to technologists who never performed FGIP procedures. Adjusted HRs were calculated for self-reported hypertension, stroke and myocardial infarction.

RESULTS: We observed a 34% increase in stroke incidence (HR=1.34, 95% CI 1.10 to 1.64) in technologists who performed FGIP compared to those who never performed these procedures. Mortality from stroke was also modestly elevated, although not statistically significant (HR=1.22, 95% CI 0.85 to 1.73). We observed no statistically significant excess risks of incidence or mortality from any other outcome evaluated.

CONCLUSIONS: Our finding of elevated risk of stroke in workers performing FGIP needs to be confirmed in studies with individual radiation dose data, but nonetheless underlines the need to keep radiation exposure as low as reasonably achievable without compromising key diagnostic information.

  • abstract

Migration, that is the study of subjects moving from one residential address to another, is a complication for epidemiological studies where exposures to the agent of interest depend on place of residence. In this paper we explore migration in cases from a large British case control study of childhood cancer and natural background radiation. We find that 44% of cases had not moved house between birth and diagnosis, and about two-thirds were living within 2 km of their residence at birth. The estimated dose at the diagnosis address was strongly correlated with that at the birth address, suggesting that use of just the birth addressin this case-control study does not lead to serious bias in risk estimates. We also review other individual-based studies of naturally occurring radiation, with particular emphasis on those from Great Britain. Interview-based case-control and cohort studies can potentially establish full residential histories for study subjects and make direct measurements of radiation levels in the dwellings in question. However, in practice, because of study size and difficulties in obtaining adequate response rates, interview-based studies generally do not use full residential histories, and a substantial proportion of dose estimates often derive from models rather than direct measurements. More seriously, problems of incomplete response may lead to bias, not just to loss of power. Record-based case-control studies, which do not require direct contact with study subjects, avoid such problems, but at the expense of having only model-based exposure estimates that use databases of measurements.

LUPATSCH JE, KUEHNI CE, NIGGLI F et al. – Population mixing and the risk of childhood leukaemia in Switzerland : a census-based cohort study. - European journal of epidemiology, 12/2015, 30, 12, 1287-1298.

  • abstract 

Childhood leukaemia (CL) may have an infectious cause and population mixing may therefore increase the risk of CL. We aimed to determine whether CL was associated with population mixing in Switzerland. We followed children aged <16 years in the Swiss National Cohort 1990-2008 and linked CL cases from the Swiss Childhood Cancer Registry to the cohort. We calculated adjusted hazard ratios (HRs) for all CL, CL at age <5 years and acute lymphoblastic leukaemia (ALL) for three measures of population mixing (population growth, in-migration and diversity of origin), stratified by degree of urbanisation. Measures of population mixing were calculated for all municipalities for the 5-year period preceding the 1990 and 2000 censuses. Analyses were based on 2,128,012 children of whom 536 developed CL. HRs comparing highest with lowest quintile of population growth were 1.11 [95 % confidence interval (CI) 0.65-1.89] in rural and 0.59 (95 % CI 0.43-0.81) in urban municipalities (interaction: p = 0.271). Results were similar for ALL and for CL at age <5 years. For level of in-migration there was evidence of a negative association with ALL. HRs comparing highest with lowest quintile were 0.60 (95 % CI 0.41-0.87) in urban and 0.61 (95 % CI 0.30-1.21) in rural settings. There was little evidence of an association with diversity of origin. This nationwide cohort study of the association between CL and population growth, in-migration and diversity of origin provides little support for the population mixing hypothesis.

  • abstract 

The Estonian study of Chernobyl cleanup workers was one of the first investigations to evaluate the possible health consequences of working in the Chernobyl area (the 30 km exclusion zone and/or adjacent territories) after the 1986 reactor accident. The cohort consists of 4831 men who were dispatched in 1986-1991 for tasks involving decontamination, construction of buildings, transport, radiation measurement, guard duty or other activities. By 31 December 2012, the follow-up of the cohort yielded 102 158 person-years of observation. Exposure and health data were collected by postal questionnaires, biodosimetry evaluations, thyroid screenings, and record-linkages with cancer, causes of death and health insurance reimbursement registers and databases. These data cover socio-demographic factors, employment history, aspects of health behaviour, medical history, work and living conditions in the Chernobyl area, biomarkers of exposure, cancer and non-cancer disease occurrence and causes of death. Cancer incidence data were obtained for 1986-2008, mortality data for 1986-2011 and non-cancer morbidity data for 2004-2012. Although the cohort is relatively small, it has been extensively examined and benefited from comprehensive nationwide population and health registers. The major finding was an increased risk of suicide. Thyroid examinations did not reveal an association with thyroid nodular disease and radiation dose, but did indicate the importance of accounting for screening when making comparisons with unscreened populations. No risk of leukaemia was observed and risks higher than 2.5-fold could be excluded with 95% confidence. Biodosimetry included GPA analyses and chromosomal translocation analyses and indicated that the Estonian cleanup workers experienced a relatively low mean exposure of the order of 0.1 Gy. One value of the Estonian study is in the methodologic processes brought to bear in addressing possible health effects from the Chernobyl accident. Twenty-five years of research are summarised and opportunities for the future listed.

SHIMADA K, KAI M - Calculating disability-adjusted life years (DALY) as a measure of excess cancer risk following radiation exposure. - Journal of radiological protection, 12/2015, 35, 4, 763-775.

  • abstract 

This paper has proposed that disability-adjusted life year (DALY) can be used as a measure of radiation health risk. DALY is calculated as the sum of years of life lost (YLL) and years lived with disability (YLD). This multidimensional concept can be expressed as a risk index without a probability measure to avoid the misuse of the current radiation detriment at low doses. In this study, we calculated YLL and YLD using Japanese population data by gender. DALY for all cancers in Japan per 1 Gy per person was 0.84 year in men and 1.34 year in women. The DALY for all cancers in the Japanese baseline was 4.8 in men and 3.5 in women. When we calculated the ICRP detriment from the same data, DALYs for the cancer sites were similar to the radiation detriment in the cancer sites, excluding leukemia, breast and thyroid cancer. These results suggested that the ICRP detriment overestimate the weighting fraction of leukemia risk and underestimate the weighting fraction of breast and thyroid cancer. A big advantage over the ICRP detriment is that DALY can calculate the risk components for non-fatal diseases without the data of lethality. This study showed that DALY is a practical tool that can compare many types of diseases encountered in public health.

 

SUSLOVA KG, ROMANOV SA, EFIMOV AV et al. - Dynamics of body burdens and doses due to internal irradiation from intakes of long-lived radionuclides by residents of Ozyorsk situated near Mayak PA. - Journal of radiological protection, 12/2015, 35, 4, 789-818.

  • abstract 

This paper presents and discusses new autopsy results and other historic data from earlier autopsies and environmental monitoring linked to releases from the Mayak PA facilities in the Chelyabinsk oblast in the southern Urals. The focus is on residents of the town of Ozyorsk located near to Mayak PA and the dynamics of body burdens and radiation doses from inhalation of plutonium alpha and americium-241, and ingestion of strontium-90 and caesium-137. It is demonstrated that accumulation and exposure from these radionuclides was mainly due to unplanned releases in the 1950s and 60s. The mean content of plutonium alpha at the time of autopsy of people commencing residence in Ozyorsk from 1949 to 1959 was about 3.5 Bq, falling to 0.2 Bq in those arriving after 1990. A reducing trend was also seen for (241)Am. The highest (90)Sr content in Ozyorsk residents was measured in 1967. The (137)Cs body content of residents arriving in Ozyorsk at any time was in almost all cases below the limit of detection. The committed effective dose from internal exposure to these long-lived radionuclides which would have been accumulated in Ozyorsk residents if present from 1949 to 2013 is estimated to be 13 mSv. This dose is primarily attributed to intakes during 1949 to 1959 when the annual effective dose rate was approximately 1 mSv y(-1). The current value is about 0.1 mSv y(-1). This dose is about 20 times higher than the dose from global man-made fallout, which is about 0.005 mSv y(-1) at present, but much lower than that from natural background radiation, i.e. about 2 mSv y(-1). The experience gained from this work and continuing activities can contribute to the development of improved international guidance in legacy situations, particularly as regards the provision and use of monitoring data to test and thereby build confidence in prognostic models for radiation conditions and potential future exposures. The scope includes evidence for the rate of reduction in radionuclide concentrations in environmental media and in their bioavailability, resuspension of long-lived alpha radionuclides, uptake of (90)Sr and (137)Cs in the food-chain, and confirmation of cumulative uptake via autopsy and whole body counting measurements. Continuing investigations will thus support decisions on future planned releases and contribute to planning of remediation of other areas affected by historic releases.

THORNE MC, WILSON J - Generally applicable limits on intakes of uranium based on its chemical toxicity and the radiological significance of intakes at those limits. - Journal of radiological protection, 12/2015, 35, 4, 743-762.

  • abstract 

Uranium is chemically toxic and radioactive, and both considerations have to be taken into account when limiting intakes of the element, in the context of both occupational and public exposures. Herein, the most recent information available on the chemical toxicity and biokinetics of uranium is used to propose new standards for limiting intakes of the element. The approach adopted allows coherent standards to be set for ingestion and inhalation of different chemical forms of the element by various age groups. It also allows coherent standards to be set for occupational and public exposures (including exposures of different age groups) and for various exposure regimes (including short-term and chronic exposures). The proposed standards are more restrictive than those used previously, but are less restrictive than the Minimal Risk Levels proposed recently by the US Agency for Toxic Substances and Disease Registry. Having developed a set of proposed limits based solely on chemical toxicity considerations, the radiological implications of exposure at those proposed limits are investigated for natural, depleted and enriched uranium.

  • abstract 

Un modèle expérimental animal, mimant la contamination chronique des populations vivant sur des territoires contaminés a été utilisé dans le cadre du programme de recherche ENVIRHOM-Santé de l’Institut de radioprotection et de sûreté nucléaire (IRSN). Il a révélé que l’ingestion chronique de radionucléides à faibles doses entraînait des atteintes biologiques multiples de faibles amplitudes caractérisées par des ruptures subtiles d’équilibres métaboliques consécutives à l’exposition interne. En effet, il a été montré qu’une contamination interne de radionucléides était capable d’affecter in vivo un certain nombre de métabolismes majeurs de l’organisme, tels que le métabolisme du cholestérol, de la vitamine D, du fer, des hormones stéroïdiennes et des xénobiotiques sans effet toxique ou apparition de pathologie. Pour compléter et affiner ces connaissances, des études associant pour la première fois une approche métabolomique à la radiotoxicologie des faibles doses ont été initiées en collaboration avec la plate-forme d’analyse métabolique à large spectre de l’université d’Aix-Marseille (CRIBIOM). Les résultats de ces études expérimentales, qui portent sur les effets biologiques d’une ingestion chronique de césium 137 ou d’uranium naturel chez le rat pendant plusieurs mois, ont permis de montrer que, suite à ces expositions internes, il était possible d’identifier des individus contaminés par de faibles doses de radionucléides (bien que leurs taux de marqueurs cliniques classiques n’étaient pas affectés) par une modification de leur métabolome. Aussi, une simple analyse sanguine ou urinaire par approche métabolomique semble pertinente pour définir la signature biologique d’une contamination interne à faible dose de radionucléide. Enfin, l’identification et la quantification simultanée de plusieurs acteurs moléculaires impactés ont permis de définir « l’empreinte métabolique » spécifique de l’exposition et pourraient permettre de révéler des biomarqueurs d’exposition, d’effets biologiques précoces, de toxicité voire d’éventuels développements pathologiques. En conclusion, la métabolomique fait partie des approches analytiques modernes dont le potentiel reste considérable dans le domaine des faibles doses.

  • abstract 

The studies of health effects in human populations living in places with high levels of natural background radiation are of crucial importance for understanding the impact of low doses of ionising radiation. The paper reviews some exemplary literature that addresses the likelihood of the radiation-induced cancer in aforementioned regions. It is shown that using Bayesian analysis one can arrive at an essentially different conclusion concerning dose-effect dependence from the one which could be guessed from first glance. The general conclusion is that cancers do not correlate with elevated radiation in regions with high natural background radiation.
