2018 EPA International Decontamination Research and Development Conference
(SUMMARY) [Published : May 28, 2019]
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...
A case study of cesium sorption onto concrete materials and evaluation of wash agents: Implications for wide area recovery
(JOURNAL) [Published : Jun 01, 2019]
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...
Evaluation of Low-Tech Outdoor Decontamination Methods Following Wide Area Radiological/Nuclear Incidents
(PUBLISHED REPORT) [Published : Sep 02, 2019]
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 Building Materials During Radiological Incident Recovery
(JOURNAL) [Published : Nov 01, 2019]
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...
Radiological Emergency: Exposure Assessment of Livestock Carcass Management
(PUBLISHED REPORT) [Published : Jun 06, 2019]
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...

Cesium Emissions from Laboratory Fires
(JOURNAL) [Published : Jun 28, 2018]
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.
Design of Ad Hoc Filtration Beds for Treating Contaminated Waste Waters Final
(PAPER IN NON-EPA PROCEEDINGS) [Published : Mar 27, 2018]
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.
Effects of Aging and Decontamination Pressure on the Penetration of Radionuclides into Concrete
(PAPER IN NON-EPA PROCEEDINGS) [Published : Mar 22, 2018]
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 ...
