Helen Grogan attended the Radiological Effluents & Environmental Workshop organized by the Nuclear Energy Institute (NEI) at Royal Sonesta in New Orleans, Louisiana, from June 25-28, 2018. This workshop “provides a forum to exchange practical experiences and issues related to the control and monitoring of radioactive effluents, environmental protection, environmental monitoring and sampling, and assessment of environmental effects, including dose to the public”.

Helen gave a presentation describing RAC’s implementation of RACER at Exelon that was very well received. RACER is now installed at all 14 Exelon sites and provides Exelon with an at-a-glance overview of effluents and environmental measurements and, if desired, the ability to examine the data in detail, too.

The 2018 workshop presentations are available for download on NEI website.

RAC Team Members at ddms Offices

RAC team meets to finalize plans for upgrades to RACER tools

RAC team members Jim Rocco, Justin Mohler, Mark Packard, Helen Grogan, Art Rood, and Lane Urtel (shown above, left to right) gathered at the ddms, inc., offices in St. Paul, Minnesota, from December 9 through 11, 2015, to discuss and finalize plans for a number of upgrades to the RACER suite of tools. The upgrades that are being implemented include:

  • NEW multi-client server setup for RACER web hosting
  • NEW dashboard user interface with multi-facility capabilities for RACER Data Analysis Tool
  • NEW web-accessible dose-based compliance system functionality in RACER Data Analysis Tool and Risk Calculation Tool

Operation Tomodachi DTRA data added to RACER

Operation Tomodachi DTRA data added to RACER

Data related to potential radiation exposures to U.S. military personnel in Japan following the accident at Fukushima Daiichi Nuclear Power Station (FDNPS) in 2011 have been added to the RACER Data Analysis and Risk Calculation Tools. These data, provided in the Defense Threat Reduction Agency (DTRA) “Operation Tomodachi Registry: Radiation Data Compendium”, include measured concentrations in soil, air, and tap water, as well as dose rates from survey meters.


RACER methodology paper published

RAC has published a paper in Health Physics describing the RACER methodology.

ABSTRACT: This paper describes a methodology called Risk Analysis, Communication, Evaluation, and Reduction (RACER*) that converts environmental data directly to human health risk to enhance decision making and communication. The methodology was developed and implemented following the Cerro Grande fire in New Mexico that burned approximately 7,500 acres of Los Alamos National Laboratory in May 2000. The absence of a coordinated and comprehensive approach to managing and understanding environmental data was a major weakness in the responding agencies’ ability to make and communicate decisions. RACER consists of three basic elements: managing information, converting information to knowledge, and communicating knowledge to decision makers and stakeholders. Data are maintained in a web-accessible database that accepts data as they are validated and uploaded. The user can select data for evaluation and convert them to knowledge using human health risk as a benchmark for ranking radionuclides, chemicals, pathways, or other criteria needed to make decisions. Knowledge about risk is communicated using graphic and tabular formats. The process is transparent, flexible, and rapid, which enhances credibility and trust among decision makers and stakeholders. The fundamental principles used in RACER can be applied anywhere radionuclides or chemicals are present in the environment.
