Advanced Gamma Real Time Mapping Solutions
RadScout GPS Gamma Survey System

Our system is used and loved by clients across North America
The RadScout gamma survey software was developed to simplify the gamma collection process and provide the ability to view and analyze the data while in the field, saving significant time and money. In addition, the software provides the ability to export data directly to shapefile format without the need to purchase expensive third-party software. Data are transferred easily by a removable drive through the tablet USB port and requires no special cables or parts.
The RadScout incorporates off-the-shelf radiological instrumentation linked to a rugged field tablet and sub-meter GPS receiver. Radiological data are tied to a GPS coordinate and stored in a robust binary file. Collected data are shown on the map in real time and support setting legends to easily identify areas of elevated gamma while surveying. The software also supports loading background layers and images, adding position features in real-time, and navigation to specified locations.

How Gamma Real Time Mapping Works
Gamma surveys demand speed and accuracy, especially in complex or contaminated areas. The RadScout system streamlines the process through:
- Real-time detection: Immediate feedback from sensitive detectors eliminates delays in data interpretation.
- Geospatial integration: GPS mapping ensures each data point is accurately tied to its location.
- Visualization tools: Interactive displays allow survey teams to identify trends, hotspots, and areas requiring closer evaluation.
This comprehensive approach reduces uncertainty, strengthens compliance efforts, and ensures that stakeholders receive clear, usable information.
