The radiological incident in Cochabamba (Bolivia, 2002), where members of the general public exposed to an unshielded Ir-192 radiation source whilst traveling on a bus was replicated here attempt asses and evaluate emerging retrospective dosimetry methodologies using objects daily life, that are either carried or close human body can be found vicinity individual. For this purpose accidental exposure simulated under controlled conditions secured area radioactive placed cargo compartment...

An experimental study of radionuclide dispersion in the atmosphere has been conducted at BR1 research reactor Mol, Belgium. Artificially generated aerosols ('white smoke') were mixed with routine releases (41)Ar reactor's 60-m tall venting stack. The detailed plume geometry was measured remote sensing (Lidar) aerosol plumes while surface radiation levels under using gamma detectors downwind distances up to 1500 m from release point. A database built simultaneous measurements and field decay,...
The reconstruction of the Cochabamba (Bolivia) radiological incident (IAEA-International Atomic Energy Agency 2004 Radiological Accident in STI/PUB/1199 (Vienna: IAEA)) was used to assess and evaluate retrospective dosimetry methodologies. For this purpose an unshielded radioactive source placed inside a transportation vehicle (bus) resembling exposure device. External doses were assessed using water anthropomorphic phantoms that at various positions equipped with both fortuitous dosimeters...
Through the Euratom 6th Framework Programme, European Commission is co-sponsoring specific targeted research project "Triage, Monitoring and Treatment—Handbook for management of public in event malevolent use radiation" (TMT Handbook). The main aim to produce a handbook effective timely triage, monitoring, treatment people exposed radiation following act. World Health Organization contributed this with development guidelines on medical health response. A training course based TMT Handbook...
An atmospheric dispersion experiment was conducted using a visible tracer along with the routine releases of 41Ar from BR1 research reactor in Mol, Belgium. Simultaneous measurements plume geometry and radiation field decay were performed as well source term meteorological parameters. Good overall agreement is found between measurement data model results mesoscale dose rate RIMPUFF.
Locations of gamma dose rate sensors have often been chosen by administrative or geometrical criteria. Nowadays computational capacity allows for a more realistic basis. We use simulations potential radioactive plumes based on weather data one year to investigate the threats regions without own nuclear power plants and find good numbers locations detect such plumes. optimise sensor minimising cost function that can take into account undetected plumes, their region in general, population....
Decision makers must react in a prompt and appropriate manner various emergency situations. The bases for decisions are often predictions produced with decision support systems (DSS). Actual radiation measurement data can be used to improve the reliability of predictions. Data assimilation is an important link between model calculations measurements thus decreases overall uncertainty DSS However, different aspects have taken into account optimal use technique: countries may differing...
In case of an accidental release radioactivity and subsequent contamination the food chain, many samples need to be collected analysed, this is far from being a simple issue. The determination levels requires accredited laboratories, approved certified procedures methods, transparency above all prompt results, as stakeholders in general cannot afford waiting. Adequate decisions require fixed norms, stable time, accepted internationally. Moreover, effective policy relies on traceability...
During the past 7th Security Framework Program European Commission funded a research project called CATO (CBRN Crisis management, Architectures, Technologies and Operational procedures) to develop prototype decision support system for crisis management in addition providing suite of guidelines first responders incident commanders when dealing with chemical, biological, radiological or nuclear incidents. In order derive these proof-of-concept experiment was setup during which several passive...
In the RODOS project data assimilation methods are under development to assess radiological situation in real time case of an accident at a nuclear power plant. Due short available take decisions during early phase judicious combination model predictions and monitoring will have be used. It is shown that actual site-specific strategies Europe not adapted this new method. A framework proposed. Assimilation simultaneous on-line gamma dose rates from detectors located around installation...
