Atmospheric dispersion modelling of radioactive contaminants

The development of the 2nd version of the SINAC programme system was finished in 2012. SINAC is developed to follow the consequences of radioactive releases of a (hypothetical) nuclear accident. Atmospheric dispersion, plume depletion by dry-out and wash-out, cloudshine and groundshine doses, dose consequences of inhalation and ingestion, early and late health effects are computed in the software. Effects of the introduction of countermeasures are also taken into account. The SINAC system has gone through a lot of development in the last few years according to users’ needs and to the Hungarian and the international regulations and protocols of radiation protection. Continuous development ensured that the SINAC environmental simulator was used as an interactive expert system in the Hungarian Atomic Energy Authority Centre for Emergency Response, Training and Analysis in the last decade. Since the latest requirements on the programme that were based on principles set forth one and a half decades ago could have been met only by considerable compromises in the future, it was claimed in 2009, that the course of development of SINAC should be reconsidered, and a new version should be created using the potentials of the present-day information technology. The common goal of the development in the last several years was to obtain easily usable, flexibly developable software that gives results comparable to those of other software products being developed in international collaboration.
