The estimation of human exposure to chemical substances and radiation ; Status of the RIVM research

De schatting van de blootstelling van de mens aan stoffen en straling ; De status van het RIVM-onderzoek

Synopsis

In 1994, the Sector Substances and Risks of the National Institute of Public Health and the Environment (RIVM) decided to strengthen strategically its research into risk assessment methodology. To further this goal, this report describes the research area of human exposure assessment at the RIVM. A representative selection of human exposure assessment models for both chemical substances and radiation is analysed with regard to aim, principle, degree of model analyses and values of default parameter. For comparison, a model to assess human exposure to micro-organisms is included as well. All models are operational or nearly so in the production of risk assessments in the Sector Substances and Risks and also in the Sectors Public Health Research and Environmental Research. The models discussed all have a defined area of application and support risk management. The research areas of exposure assessment for substances and radiation are compared and many methodological analogies are apparent. However, at the level of models and parameters an in-depth analysis of analogies and explained or unexplained differences is lacking. In this report a first attempt is made. Recommendations are made with respect to the goals to reach at the RIVM. Within the scope of this RIVM management project it is concluded that an important goal of this project, i.e. furthering internal harmonisation and communication in the area of human exposure assessment, is reached.
