[en] The thirty four papers presented at this second International Radioecology Symposium organized by the CEA and EDF under the aegis of the International Union of Radioecologists were divided into six sessions enabling the following subject matters to be covered: session 1 - power station siting and environment; session 2 - methodology; session 3 - site studies; session 4 - day long study along the Rhone (21.6.79); session 5 - process of radionuclide transfers; session 6 - radioecological control. Four papers submitted during a 'poster' session concluded the work sessions

[en] Ecolego is a Matlab toolbox for modelling dynamic systems and to perform risk assessments using model simulations. The toolbox supports linear and non-linear systems, modelled in continuous time, sampled time, or a hybrid of the two. The Graphical User Interface of Ecolego facilitates the transition from a conceptual model, represented with an interaction matrix, to a mathematical model implemented in Simulink. Ecolego includes routines for probabilistic simulations, correlation between parameters, sensitivity analyses, uncertainty analyses and parameter optimisation. Even though the toolbox can be used to simulate any species and dynamic system, it has been specially designed to fulfil specific needs in the field of radioecological risk assessment. Ecolego includes a library with radionuclide data and it supports automatic consideration of radionuclide decay chains. This paper provides an overview of the functioning and features of Ecolego.

[en] This is latest in a series of joint reports presenting results of measurements of radioactivity in the environment through the analysis of a diverse range of samples including foodstuffs, soil and air samples and other direct measurements of radioactivity in the environment from around nuclear sites and other locations throughout the United Kingdom. Both our Agencies are committed to ensuring that radiation doses are well below national dose limits to protect public health, the environment, consumer interests and monitoring the effects of industry. The report presents data for 2001 and shows that consumers were not exposed to unacceptable doses as a result of their diet

[en] The FASSET EC funded project has created a generic framework for assessing the impact of radioactive contamination on non-human biota. Effects analysis forms an integral part of the framework and this paper describes the structured method used for collating information from the available literature on the biological effects of radiation. This paper illustrates the function of the FASSET radiation effects database (FRED) using a worked example as a demonstration. (author)

[en] Radiating conditions in republic remains intense. The complication of radiating conditions in territory of Republic Kazakhstan is caused: by activity of former Semipalatinsk test nuclear range; by nuclear explosions executed for the decision of economic task; by functioning of the enterprises of a nuclear-industrial complex and connected with production and processing of poly metal ores, oil and gas; by natural anomalies of radionuclide in objects of an environment. The radioactive deposits on traces of radioactive clouds were distributed to territory 304 thousand km², on with lives more than 1.7 m. persons. In 711 settlements the effective doze exceeded sanitary annual norm at a rate of 0.1 rad. The maximal meanings reach 448 rad for the whole period of tests (s.Dolon). For an estimation of a radiating situation practically in the whole territory of a Semipalatinsk zone of ecological disaster dURING 1993 - 1996 the radioecological researches which have allowed to reveal and localize territory with above permitted standard pollution radionuclides as artificial, and natural origin, and also heavy metals and other toxic elements are carried out (spent). However there is poorly investigated a situation with a level of pollution plutonium-239 and other transuranium elements.Only last years the radiating inspection of the third of territory of republic, 34 cities and 55 settlements is carried out (spent), where is revealed and up to thousand unattended radioactive sources and subjects is withdrawn, some hundreds sites of radioactive pollution are located. Nowadays in Kazakhstan the large work on the tx of the information about all radiating supervision in territory of republic for last 40 years is carried out and these items of information prepare for the opened publication as the collection 'Radioecological conditions in Republic Kazakhstan'

[en] This report presents the results of the marine environmental radioactivity monitoring surveys of intertidal and underwater areas around nuclear submarine berths which were carried out by DRPS during 2000. Also included are results of smaller scale intertidal surveys carried out by local staff but coordinated by DRPS. Cobalt-60, the nuclide of major importance in naval discharges, was detected in a number of samples but in many cases was attributable to discharges by other operators. Concentrations in any case were found to be low, and at no survey location did the calculated annual radiation dose commitment to the most exposed members of the general public due to the presence of cobalt-60 exceed 1% of the ICRP principal dose limit for members of the public (1000μSv). These results are consistent with those obtained in the independent monitoring programmes as reported in the Radioactivity in Food and the Environment (RIFE) annual reports. It is concluded that existing discharge arrangements are providing effective control over environmental levels of radioactivity, and that there has been no radiological hazard to any member of the general public during 2000 from the operation of nuclear powered submarines.

[en] It is possible to analyse a diverse range of samples for environmental investigations. The main types are soil/sediments, vegetation, fauna, shellfish, waste and water. Each type of samples requires different storage and collection methods. Outlined here are the preferred methods of collection to ensure maximum sample integrity and reliability. (author)
