Idaho Falls: The First Nuclear Meltdown in America’s History

Written by Bryan W Sommers - SGM U.S. Army, Ret. on 11 April 2024

The explosion at SL-1 U.S. Army research facility near Idaho Falls in 1961 during the early years of nuclear power development was a grim and tragic reminder of the power and danger of nuclear fission. The accident resulted from a range of factors, including inadequate design, inadequate materials testing, and poor procedures and training.

Transportation emergency preparedness with radiation simulators

Written by Bryan W Sommers - SGM U.S. Army, Ret. on 28 November 2022

Emergency preparedness starts with building confidence and familiarity with key radiological terminology and instrumentation. This is especially the case when training for transportation emergencies.

While there’s a minimal chance of responders being exposed to harmful quantities of ionizing radiation during daily duties, there is still the very real risk of encountering radioactive material when attending the scene of a transportation accident.

This is why emergency personnel need access to key training and technical assistance to safely and effectively mitigate the effects of radiation incidents.

In this article, we’ll look at:

  • How the Transportation Emergency Preparedness Program (TEPP) can teach responders how to react to radiation accidents
  • The importance of real-experience training to support emergency preparedness
  • A new training tool which can elevate responder radiation training

A Guide to the Five Levels of HazMat Response

Written by Bryan W Sommers - SGM U.S. Army, Ret. on 28 October 2022

HazMat training is essential when responding to hazardous materials which have been mishandled, incorrectly transported, or used with malicious intent, as they can pose a substantial risk to human health and the environment.

How effectively these incidents are managed and resolved hinges on the knowledge, training, and skill of those charged with the response.

Using simulated sources to train for live radiological incidents

Written by Bryan W Sommers - SGM U.S. Army, Ret. on 27 April 2021

Training is an essential aspect of preparing radiation professionals for the realities of live radiological incidents, whether they are operating in the field of first response, law enforcement, customs and border control or the military.

While much of the essential theoretical and regulatory information can be conveyed in the classroom setting, there is also the vital need to exercise, hone and verify that knowledge through hands-on training.

The use of simulation within a chemical, biological, radiological or nuclear (CBRN) training environment is not a new concept. 

Over the years, CBRN instructors have become well used to employing a variety of different simulation types - from notes written on index cards, to the calling out of verbal cues over the trainee’s shoulder, or the use of multiple harmful chemicals as false positives that react to chemical detectors.
