We provide a wide range of services. Please contact us with any questions.

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 cannister have been approved by the NRC.
