Our team

Our team of engineers and health physicists are skilled in both radiological instrumentation and hardware design. This allows us to design and create unique solutions to difficult problems associated with radiation detection.

Software Development

From embedded systems to custom applications.

Quality Assurance

Our quality assurance management plan ensures each system is tested completely and thoroughly.

Acceptability

Our strong knowledge of radiation detection allows us to fully quantify all aspects of the detection system.

Hardware

We work closely with fabricators and CAD designers to ensure the system is built to work.

ERG has decades of experience with providing advanced technical solutions for difficult problems associated with radiological detection and characterization. Below are just a few key examples of our technical experience.

Alpha/Beta Pipe Scanner

ERG was tasked with releasing several dozen pipes from a uranium facility. In order to scan the interior of the pipes, ERG developed a pipe scanner capable of scanning 100 percent of the interior surface for both alpha and beta contamination. The pipe scanner contained 12 Geiger Muller detectors in a circular pattern, a front facing camera for navigational purposes, and a stepper motor for driving the scanner at a pre-defined scanning speed.

ERG personnel designed the pipe scanner to meet specific detection capabilities and performed all software development to remotely view the scanner camera, control the speed, and collect the radiological data for documentation. The scanner was successfully used to release approximately 100 8-inch, and 10-inch diameter pipes in 2014.

GPS Gamma-Scanning MDC Calculator

With the growing popularity of using GPS for gamma radiation surveys, the need to quantify the scanning detection capability has become necessary. ERG has developed an online tool to assist with approximating the MDC for GPS-based scanning surveys.

ERG personnel automated MCNPX and performed all the technical analysis to build the database of numerical values required to determine MDCs. The approach has been approved and published by the Health Physics Journal.

Nuclide Decay Software

The Nuclide Decay Software was written to solve the N-dimensional Bateman system of equations for radioactive decay. The software features an interactive graphical user interface with the ability to easily model parent-progeny relationships and growth from external sources.

Using the software, the activity or number of atoms of a radioactive isotope and its decay progeny can be calculated as a function of time.

The software was initially written for internal use, but has since been available to download for free. The software has been used by numerous universities and has continued to receive positive feedback from users.

Remotely Operated Surveying System

The Remotely Operated Surveying System was developed for monitoring trenches that are inaccessible by personnel. The system transmits data, such as video feed, alpha counts, and proximity measurements to a base computer where alpha results corresponding video feed are saved for documentation purposes.

The system was designed for a one-time-use characterization of trenches containing very high levels of contamination.
