Why do we need to rebuild trust? • Radiation risk assessment is a complex subject • Not feasible to “educate” stakeholders thoroughly • A level of trust has to be established between stakeholders and scientists • Stakeholder acceptance is essential for successful recovery decisions
Where does trust come from? • Sound science • State of the art methods • Intense scientific peer review • Transparency • Availability and accessibility of information • Responsiveness • Taking actions beyond what is expected
Inhalation of resuspended plutonium contaminated soils – dominant exposure pathway
We concluded a rancher living on the land with his family is the scenario that would lead to the highest dose
A prairie fire could significantly increase the dose because of greater resuspension following the fire.
Rancher with probability of fire = 1 Curve A Rancher scenario Curve B Child scenario Curve C Resolution of Soil Action Level at Rocky Flats 1 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 Probability of Exceeding Dose Limit 10% level 239+240Pu (Bq kg-1) 1000 2000 3000 4000 5000
How do we build trust? • Consistent efficient process for compiling, accessing and analyzing environmental data • Comprehensive, geared to end use • Convert data into knowledge • Flexible, rapid, current • Communicate the knowledge • Transparent, understandable, cannot be delegated
Data Information Knowledge Optimize sample locations Spatial and temporal trends Turning Data Into Information and Knowledge
How do we maintain trust? Establish the ability to re-evaluate decisions as new information becomes available Ensure a transparent process that allows decisions to be traced back to the information they were based upon Establish the ability to allow other factors (e.g., economic, cultural, political) to be accounted for in decision making Effectively communicate the basis for decisions
