On May 8-10, 2018, the U.S. Environmental Protection Agency’s (EPA’s) Office of Research and Development’s National Homeland Security Research Center (ORD/NHSRC) hosted the 10th U.S. EPA International Decontamination Research and Development Conference at the EPA facilities in Re...

The sorption and desorption properties of radionuclides onto common building materials such as concrete are critical factors in the improvement of techniques for mitigating a release of nuclear or radiological material to the urban environment. A potential option for the early p...

This technology evaluation report included use of low-tech decontamination methods on surfaces common to outdoor residential environments and included evaluating the decontamination efficacy, method constraints, safety concerns, feasibility, waste generation, potential exposure, ...

High pressure decontamination of certain surface building materials is concluded to be a promising rapid, readily available response technique, with the data from this study informing its practical implementation. Removal efficacy of radionuclides from concrete are high when perf...

The potential exposures and exposure pathways were compared for various options to support decision-making in the event of a radiological emergency to provide an in-depth evaluation based on understanding of ionizing radiation and radiation exposure, conceptual models of potentia...

Presentation; The study was devised to connect emergency management and homeland security offices at the city, state, and federal agencies and discuss the availability and potential response capabilities of equipment reserves.

This journal article studied the partitioning of Cs between airborne particulate and residual ash from burning Cs-contaminated vegetation as a function of particle size distribution (PSD), and to correlate Cs emissions with carbon-containing compounds and combustion efficiency.

Sensitivity analyses on the system parameters revealed simple relationships between the bed design and the expected breakthrough of cesium, allowing us to generate a concise set of look-up tables to aid the early responders.

This study aims to understand the effect of the rapid decontamination methods of high pressure washing and washing with salt additives on the penetration of radionuclides into concrete. To this end, we first identified how penetration profiles of Cs-137, Sr-85, and Eu-152 evolve ...

During the immediate, emergency phase of a response, it will be impossible to initiate activities other than establishing life-saving operations and securing a site for the safety of the public and first responders. This report contains a comprehensive list of proposed equipment ...

Report

If a terrorist event or natural disaster causes a wide area of land to be contaminated with chemical, biological, or radiological particulates, emergency responders need a rapid way to determine where to sample and decontaminate prior to clearing the area. A comprehensive stormwa...

EPA’s Waste Estimation Support Tool (WEST) is a GIS-based decision support tool for estimating the characteristics, amount, and residual radioactivity of waste generated from remediation and cleanup activities after a radiological incident, including those involving radiological ...
