The assessment of changes, either sudden or over time, is essential in guiding the immediate response to, the recovery from, and the remediation of these changes. The ability to assess an event – whether an earthquake or the releases of radioactive materials – immediately is critical in order to minimize the impact. Data collected during the assessment provide the necessary input for models to predict further changes and guide intervention and response.

For example, after the releases of radioactive materials, the effective and sustained mapping of radioisotope contamination in complex, three-dimensional topographies is critical for predictive modeling, determining the disposition of areas with increased dose levels, and guiding response and remediation activities. IRC scientists develop new detection concepts and systems that combine sensitive radiation detection and imaging instruments with complementary environmental sensors. These use a variety of ground and aerial vehicles such as trucks and helicopters, which are outfitted with advanced detection systems developed at Berkeley Lab/UC Berkeley.

In addition, advanced models have been developed to estimate radiation activities and doses on the ground over different spatial and temporal scales, promising a more effective and accurate mapping of contamination.
