Health Physics Professional Services

We Are Here To Help You

Our team of certified health physicists and engineers

can handle any health physics task, no matter how large or small.

Remediation Planning and Reclamation

ERG has assisted with developing and executing the reclamation plans for eight sites where cleanup costs exceeded more than $10 million dollars each.

Our services include RSO management, regulatory analysis, reclamation, auditing, radiation protection, and much more.

Radon Flux Measurements

ERG uses a radon flux canister designed to comply with EPA Method 115 for making radon flux measurements under 40 CFR Part 61. The canister is a one-piece self-contained unit designed to make the removal and replacement of activated charcoal for each flux measurement unnecessary.

ERG maintains a laboratory consisting of a shielded detector, gamma spectroscopy system, and database dedicated specifically for counting radon flux canisters.

On-Site Laboratory

ERG maintains instrumentation and technicians to support radiation protection programs, including dose-rate instruments and instruments for making surface contamination measurements.

Breathing zone, low volume, and high-volume air samplers are used to obtain air samples that are analyzed on-site for gross alpha and gross beta emissions. Standard Operating Procedures are available for the calibration, set up, and operation of all instruments.

Real-Time Monitoring

ERG maintains a variety of instruments used for environmental monitoring and data collection of various constituents.

Our monitoring capabilities include radon concentrations, exposure rate measurements, high/low volume air sampling, and gamma spectroscopy.

Over the last 20 years

ERG has had the principal health physics and excavation monitoring support role in eight large uranium and/or thorium contaminated projects where the cost of each project exceeded $10M (two sites owned by Dow Chemical Co, one Molycorp Site, and the KAFB OT-10 Site). On-site laboratories were setup and operated for each of these projects by ERG personnel.
