Decontamination of urban surfaces contaminated with radioactive materials and consequent onsite recycling of the waste water
(JOURNAL) [Published : Feb 04, 2021]
Enhancing rapid remediation strategies is paramount for recovery after a large-scale nuclear contamination event in an urban environment. Some current strategies recommend use of readily available equipment, materials, and facilities to expedite recovery. For example, applying pr...

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...
Evaluating Solid Sorbents for Recycling Wash Waters Containing Strontium and Calcium
(JOURNAL) [Published : Jan 01, 2019]
A radiological release from a radiological dispersal device (RDD) or an improvised nuclear device (IND) has the potential to contaminate a vast area both near the dispersal epicenter and via atmospheric deposition of small particles containing the more volatile contaminants. Rapi...
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...
The Use of Hollow Fiber Dialysis Filters Operated in Axial Flow Mode for Recovery of Microorganisms in Large Volume Water Samples with High Loadings of Particulate Matter
(JOURNAL) [Published : Apr 05, 2019]
The objective of this study was to evaluate axial flow hollow fiber ultrafiltration (HFUF) in the recovery of target organisms in large volumes of turbid water that would be similar to water encountered in the cleanup of a biologically contaminated area such as the B. anthracis c...
Tools to Expedite an Urban Radiological Recovery Effort
(PRESENTATION) [Presented : Sep 24, 2019]
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.

Municipal and commercial equipment for radiological response and recovery in an urban environment: state of science, research needs, and evaluation of implementation towards critical infrastructure resilience
(PUBLISHED REPORT) [Published : May 01, 2018]
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 ...
Persistence and Decontamination of Radioactive Cesium in a Model Drinking Water System
(PUBLISHED REPORT) [Published : Jul 17, 2018]
The objective of this report was to evaluate the persistence of radioactive cesium-137 (Cs-137), on concrete-lined, copper, and polyvinyl chloride (PVC) pipe, and possible decontamination approaches. During this study, conditions within operational drinking water pipes were simul...
