Quantaflux is certified under the Section 8(a) Program of the U.S. Small Business Administration and is actively seeking new contract opportunities in the areas of health physics, homeland security, radiological emergency preparedness, radiological incident response, radioactive waste characterization, and environmental remediation. 


Quantaflux provides high-quality products and engineering services to a variety of clients throughout the United States, including the U.S. Environmental Protection Agency (EPA), prime contractors to the Department of Energy (DOE) and Centers for Disease Control, major universities, and cancer treatment centers.  Products and services have included radioactive waste characterization, radiation survey meter calibration, environmental sample analyses by gross alpha and gross beta counting, in situ gamma spectroscopy, thermoluminescent dosimeter (TLD) manufacturing and processing, and various other health physics-related engineering and consulting services.  Quantaflux currently has four Certified Health Physicists (CHPs) on staff.


Quantaflux, LLC was founded in 1995 in San Jose, California, and is now headquartered in Dayton, Ohio.  Initially, our primary product was thermoluminescent dosimeters (TLDs), manufacturing and processing.  TLDs are small devices used to measure radiation dose.  Our TLD customers are primarily cancer therapy centers with need to test radiation generating machines and to monitor radiation dose to patients undergoing therapy.  Two other services initially offered and later discontinued were a leak testing service which involved assaying cotton swab samples for radioactivity and a radiation survey meter calibration service.  In 1997, the company moved to Dayton, Ohio and began providing radiological engineering contract services to various users of radioactive materials. 


The U.S. Environmental Protection Agency (EPA) currently utilizes Quantaflux professionals for radiation safety services at their facilities in Cincinnati, Ohio.  Services include sealed source maintenance, NRC compliance inspections, instrument calibrations, radioactive waste characterization and preparation, decommissioning/decontamination activities, and personnel exposure control and assessment.  In 2007, surveys for radioactive contamination were also conducted at the U.S. EPA, Robert S. Kerr Environmental Restoration Research Center in Ada, Oklahoma.

Since December 2003, Quantaflux has been providing professional health physics support to Oak Ridge Associated Universities (ORAU) in support of the Energy Employees Occupational Illness Compensation Program Act (EEOICPA).  Specifically, Quantaflux personnel have conducted research of historic radiological activities at various Department of Energy (DOE) and Atomic Weapons Employer (AWE) sites, performed individual dose reconstructions, authored Technical Basis Documents (TBDs), and evaluated sites for inclusion in the Special Exposure Cohort (SEC).

The Non-Destructive Analyses (NDA) program at the DOEs Mound Site, in Miamisburg, Ohio, was developed, managed, and operated by Quantaflux.  This program, which utilized in situ gamma spectroscopy, was used to characterize radioactive waste being shipped to the Nevada Test Site (NTS), Envirocare, and the Savannah River Site (SRS).  This program was active for 5 years, from 2001 through 2006, and withstood multiple audits by both NTS and SRS.  Also at Mound, Quantaflux personnel provided health physics-related technical support to the radiological control organization.  Quantaflux personnel were also actively involved in Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) surveys.  MARSSIM-related activities have included development of Verification Sampling and Analysis Plans, resolution of issues with regulators and other stake-holders, resolving technical issues involving radiation detection instrumentation, data analyses, and preparation and review of Final Status Survey Reports.

In 2005 and 2006, Quantaflux personnel installed and developed procedures for the operation of a gamma-spectroscopy waste drum assay system at the Idaho National Laboratory (INL).  This system was used to assay buried waste that had been excavated and staged for shipment to NTS or the Waste Isolation Pilot Plant (WIPP).

In 2006 and 2007, Quantaflux provided professional health physics support to the Veterans Affairs Hospital in Brentwood, California.  Specific activities have included the development and implementation of MARSSIM contamination survey plans for the Brentwood Dog Park, an area suspected of having buried radiological contamination from activities during the 1950s and 1960s.

The University of Texas MD Anderson Cancer Center has been a major TLD customer since the year 2000, currently purchasing over 160,000 high-precision TLDs per year.  Other TLD customers include the Mayo Clinic, Cleveland Clinic, and numerous other hospitals and universities throughout the United States.
