Remediation Planning and Reclamation
|
| ERG has assisted with developing and executing the reclamation
plans for multiple sites where cleanup costs exceeded more than $10 million dollars each.
Activities included regulatory analyses, site characterization, reclamation plans,
verification plans and completion reports, radiological surveys, site management,
environmental monitoring, performance assessments, radiation protection and health and
safety, developing and operating on-site laboratory, and remedial design. Primary
experience has been in radiologically contaminated sites.

Equipment Rental
|
| ERG owns a large inventory of radiological and
industrial hygiene equipment for personnel monitoring and site characterization of radiological and chemical
contaminants. This equipment includes automated data collection systems for characterizing radiological contaminants
on building surfaces and within surface soils. Go to equipment page

Preparation of Radioactive Material License Applications
|
| Experienced professionals prepare initial
and renewal radioactive material license applications. This work may include conducting baseline studies,
preparing dose assessments using RESRAD and MILDOS computer applications, accident analyses, preparing
radiation protection and environmental monitoring programs, preparing standard operation procedures, and
assisting the license implement programs.

Radiological Engineering/Special Problems
|
| ERG health physicists and engineers assist clients in
developing solutions to special problems involving radiation detection systems, data handling and presentation, and
software development.

Indoor and Outdoor Radiological Surveys Using Automated Positioning Systems
|
| ERG began conducting GPS-based radiological
surveys in 1994. Since then we have continued move forward in the development and integration of innovative
survey methods and technologies. ERG has used its 3-DISS for automated indoor scanning surveys at National
Laboratories where we have surveyed floors and walls for multiple radionuclides. Maps showing radiation
level isocontours can be produced on site using ArcGIS Software. These maps along with correlation data are
used to delineate areas requiring additional decontamination. This method has been demonstrated to provide
more than 50 per cent savings compared to conventional surveys.

Radon Flux Measurements
|
| An improved radon flux canister design has been
developed to comply with EPA Method 115 procedures 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. Capability for making up to 125 individual measurements during
any period of time exists. Thousands of measurements have been made to date. The procedures for use with this
flux canister have been approved by the NRC.
