Purpose: Over the past 60 years a great number of very large datasets have been generated from the experimental exposure of animals to external radiation and internal contamination. This accumulation of “big data” has been matched by increasingly large epidemiological studies from accidental and occupational radiation exposure, and from plants, hum...

Direct quantitative assessment of health risks following exposure to ionizing radiation is based on findings from epidemiological studies. Populations affected by nuclear bomb testing are among those that allow such assessment. The population living around the former Soviet Union’s Semipalatinsk nuclear test site is one of the largest human cohorts...

Dose and dose-rate effects

In order to quantify radiation risks at exposure scenarios relevant for radiation protection, often extrapolation of data obtained at high doses and high dose rates down to low doses and low dose rates is needed. Task Group TG91 on ‘Radiation Risk Inference at Low-dose and Low-dose Rate Exposure for Radiological Protection Purposes’ of the Internat...

В настоящее время Международная комиссия по радиологической защите (МКРЗ) предлагает экстраполировать результаты эпидемиологических исследований по оценке влияния больших доз и высоких мощностей доз излучений на малые дозы и низкие...

The debate surrounding possible adverse health effects from the civil use of nuclear power under normal operating conditions has been on-going since its introduction. It was particularly intensified by the detection of three leukaemia clusters near nuclear installations, i.e. near the reprocessing plants in Sellafield and Dounreay, UK, and near the...

The relationship of low-dose background gamma radiation and childhood leukaemia was investigated in a number of studies. Results from these studies are inconclusive. Therefore, in the present study 25 years of German childhood cancer data were analyzed using interpolated background annual gamma dose rate per community in an ecological study. The ma...

Background: Some above ground nuclear tests conducted from 1949 to 1962 at the Semipalatinsk Nuclear Test Site led to radiation exposure of the public. We conducted medical examinations for hypothyroidism, thyroid cancer, and thyroid nodules with the purpose of providing documentation that might be used in determining whether these exposures had an...

It is well known that exposures like those from 226Ra, 224Ra and Thorotrast® injections increase the risk of neoplasia in bone marrow and liver. The thorium-based radioactive contrast agent Thorotrast® was introduced in 1929 and applied worldwide until the 1950s, especially in angiography and arteriography. Due to the extremely long half-life of se...

Health effects from environmental exposures to ionising radiation in Kazakhstan are considered to derive from uranium mining and from nuclear bomb testing. Little attention has been paid so far to mining, but a larger attention to the testing. Thus, this paper focusses on the latter topic. Nuclear bomb testing at the Semiplatinsk Nuclear Test Site...

The biological effects on humans of low-dose and low-dose-rate exposures to ionizing radiation have always been of major interest. The most recent concept as suggested by the International Commission on Radiological Protection (ICRP) is to extrapolate existing epidemiological data at high doses and dose rates down to low doses and low dose rates re...

Epidemiological miner cohort data used to estimate lung cancer risks related to occupational radon exposure often lack cohort-wide information on exposure to tobacco smoke, a potential confounder and important effect modifier. We have developed a method to project data on smoking habits from a case-control study onto an entire cohort by means of a...

The nuclear bomb testing conducted at the Semipalatinsk nuclear test site in Kazakhstan is of great importance for today’s radiation protection research, particularly in the area of low dose exposures. This type of radiation is of particular interest due to the lack of research in this field and how it impacts population health. In order to underst...

Background: To follow up populations exposed to several radiation accidents in the Southern Urals, a cause-of-death registry was established at the Urals Center capturing deaths in the Chelyabinsk, Kurgan and Sverdlovsk region since 1950. Objectives: When registering deaths over such a long time period, quality measures need to be in place to ma...

To some exten...

The Fukushima accident was the consequence of a preceding 2-fold natural catastrophe: the earth quake of 11 March 2011 and the subsequent tsunami. Due to favourable winds and to evacuation measures the radiation exposure to the general population in Japan as a whole and with some exceptions in the region outside the evacuation zone, too, was low. I...

Analyses of lung cancer risk were carried out using restrictions to nested case-control data on uranium miners in the Czech Republic, France, and Germany. With the data restricted to cumulative exposures below 300 working-level-months (WLM) and adjustment for smoking status, the excess relative risk (ERR) per WLM was 0.0174 (95% CI: 0.009-0.035), c...

Several recent efforts in the radiation biology community worldwide have amassed records and archival tissues from animals exposed to different radionuclides and external beam irradiation. In most cases, these samples come from lifelong studies on large animal populations conducted in national laboratories and equivalent institutions throughout Eur...

The biologically based two-stage clonal expansion (TSCE) model is used to analyze lung cancer mortality of European miners from the Czech Republic, France, and Germany. All three cohorts indicate a highly significant action of exposure to radon and its progeny on promotion. The action on initiation is not significant in the French cohort. An action...

A German case–control study on leukaemia in children below 5 y of age near nuclear installations showed a trend of increasing risk with decreasing distance of place of residence from the sites. The radiation exposure from the sites is considered as being too low by a factor of at least 1000 to explain the observed effect, but little is known about...

The recent epidemiological study on childhood cancer in the vicinity of nuclear power plants (KiKK) shows that the cancer risk, especially the leukaemia risk, for children below the age of five in Germany increases with increasing proximity to the site of a nuclear power plant. Earlier ecological studies had found an increased leukaemia risk in chi...

Based on the finding of an increased leukaemia risk among young people (aged 0-24) in the small village of Seascale, south of the Sellafield reprocessing plant, a discussion started on whether there is in general an elevated number of leukaemia cases to be observed in the vicinity of nuclear power plants. An overview on existing findings leads to t...

Background It is well established that lung cancer is caused by radon, while uncertainty exists as to whether cancers other than lung might be related to exposure from radon. To investigate further the risk of extra-pulmonary cancers, mortality data from the German uranium miners cohort study are analysed. Materials and methods The cohort includes...

Epidemiological evidence of lung cancer risk from radon is known since the early 1960s, when first studies on uranium miners were published. The risk was modeled in terms of relative risk in dependence on cumulated exposure. Since then, follow-up of studies has been extended, which allowed the analysis of modifying factors such as time since exposu...

From 1946 to 1990 extensive uranium mining was conducted in the southern parts of the former German Democratic Republic. The overall workforce included several 100,000 individuals. A cohort of 59,001 former male employees of the Wismut Company was established, forming a large retrospective uranium miners' cohort for the time period 1946-1998. Mean...

An increased risk of cardiovascular diseases after exposure to low doses of ionizing radiation has been suggested among the atomic bomb survivors.
