Abstract
A significant number of mobile radiological units are in operation worldwide aiming to provide reliable radiological data. They mainly have been designed and constructed on a national basis according to the particular needs and commitments of the specific laboratory or country. In most cases, these units are intended to be used in emergency situations for in-situ radiological measurements of accidentally released radioactivity, sometimes for monitoring environmental pollution. As the purpose of these units is very diversified in regard to the kind of vehicle and its in-built measuring equipment the varying outfit of these units cannot be adopted in general for other countries aiming to improve their capability for in-situ radiological measurement. In order to achieve harmonization of equipment and comparability of radiological data being obtained from field measurements it is necessary to have general guidelines available for designing mobile radiological units taking into account different sceneries and tasks to be achieved. In the very early stages of an accident most of the information available on the quantity of radioactive material being released, its radionuclide composition and the likely progression of the accident will come from the operator, and will be based on the conditions in the plant.

Few environmental monitoring results from off-side can be expected within the first few hours. In this very early phase, decisions on the application of protective measures will therefore, be based largely on plant status and forecasts of changes in that status as well as on meteorological data. As time progresses, results will increasingly become available from the monitoring of radionuclides in the environment (e.g. dose rates and concentration of radionuclides in air and particular materials such as water, food etc). Monitoring results can be used to estimate potential doses to people and the need for further protective measures can thus be determined from a comparison with intervention level of dose. Decision making in an emergency will however be more rapid and effective if the intervention levels of dose are expressed in terms of level of radionuclides presented in an appropriate environmental materials. The latter are termed 'derived intervention levels (DILs)' and are the practical expression of the intervention level of dose. Contamination of an environmental material at the derived level is predicted to result in an exposure at the intervention level of dose. The need for, and extend of, protective measures can be determined by direct comparison of the monitoring results with the derived levels.}
