U.S. EPA Superfund Radiation Risk Assessment is a full-day advanced course that focuses on specific technical and regulatory issues that site managers (e.g., RPMs, OSCs) and technical staff address when managing sites under the U.S. Environmental Protection Agency's Superfund remedial program that have a risk assessment conducted for radioactive contaminants. By taking the course, participants achieve the following objectives:

• Learn a step-by-step approach to the Superfund remedial program’s risk assessment process for radioactive contamination. The course discusses of the major steps in Superfund remedial program’s risk assessment for radioactive contamination and the EPA recommended guidance documents and calculators and or models for conducting such risk assessments.
• Explore methods for conducting site-specific risk assessments. The course examines how to alter the default input parameters in the Superfund remedial program’s risk and dose assessment calculators.
• Discover practical recommendations for improving the radiation risk assessments conducted at your site. The course stresses some obvious and other less obvious aspects helpful in improving the radiation risk assessment process.
• Master information about the radiation risk assessment process. Participants obtain information from experienced professionals about the radiation risk assessment process.

The instructional methodology for this course includes lectures and demonstrations of using EPA’s risk and dose assessment calculators developed by the Superfund remedial program.  Please bring your LAPTOP to this training!!!

The target audience for this course is site managers, risk assessors and others that want to obtain a working knowledge on conducting Superfund radiation risk assessments.

"Radiation Risk Assessment - Radiation Risk Assessment: Updates and Tools." https://clu-in.org/conf/itrc/rads_051507/
Modules 3 and 4 provide a quick tutorial on using the PRG calculator and a hypothetical site example of using the PRG calculator

"Decontamination and Decommissioning of Radiologically-Contaminated Facilities" https://clu-in.org/conf/itrc/radsdd_040308/
Module provides a quick tutorial on using the BPRG and SPRG calculator
