About
Radiation Emergency Services delivers advanced tools, planning expertise, and simulation support to improve radiological and nuclear emergency preparedness worldwide. Our mission is to modernize response training and exercises by combining operational realism, science-based tools, and field-tested planning strategies.
​
We specialize in:
-
Simulation-based training, including our proprietary GPS-enabled software, RadTeamSim.Route, which allows responders to train in dynamic, real-world locations
-
Full-spectrum exercise support, from tabletop design to large-scale, multi-agency field drills
-
After-action analysis and development of decision-support tools to drive improvements in plans and procedures
-
Custom radiological maps and data products to support both training and operational decision-making
Our team has supported exercises around the world, including senior planning and coordination roles for national and international radiation response drills. One of our previous efforts, Concrete Shield, was a recurring multinational exercise that simulates nuclear or radiological disaster response, humanitarian coordination, and long-term recovery operations. Past iterations have included realistic cross-border scenarios—such as a fictional incident at a Ukrainian nuclear plant along the Danube River, with full participation from Romanian emergency services and U.S. humanitarian response teams.
At Radiation Emergency Services, we work alongside emergency management professionals, humanitarian agencies, and technical specialists to deliver high-impact training that prepares teams for the most critical hours of a nuclear or radiological emergency.

The Founder
President, Principal Scientist
Trusted Professional
Dr. Wendy Renno is the founder and president of Radiation Emergency Services, a company dedicated to advancing radiation disaster preparedness and response through science-based training, simulation, and operational support. She brings nearly two decades of hands-on experience in real-world nuclear and radiological incidents, large-scale federal exercises, and the development of advanced preparedness tools.
Dr. Renno is the creator of RadTeamSim.Route, an immersive simulation platform designed specifically for training offsite responders in complex radiation emergencies. This tool has been used to enhance responder readiness by providing realistic, GPS-enabled, physics-based scenarios that bridge the gap between classroom instruction and field operations.
Since 2010, Dr. Renno has supported the U.S. Department of Energy (DOE) and National Nuclear Security Administration (NNSA), serving in key scientific and technical roles within the Consequence Management (CM) program at the Remote Sensing Laboratory. She has held multiple positions in support of the Federal Radiological Monitoring and Assessment Center (FRMAC) and served as a lead assessment scientist during the Fukushima Daiichi Nuclear Power Plant emergency. In that role, she helped produce critical radiological data products used by the U.S. Department of Defense, Department of State, the White House, and the Government of Japan.
In recent years, she has played senior planning and leadership roles for national-level DOE exercises. Most notably, she served as the overall lead planner for Cobalt Magnet 2025, a multi-state radiological emergency preparedness exercise hosted in Michigan with participation from federal, state, and international partners.
Academic Background
Wendy earned both her Doctor of Philosophy in Radiochemistry and a Bachelor of Science in Chemistry from the University of Nevada, Las Vegas.
