Radiation mapping system

Southern Scientific has produced a new radiation-detection system that uses GPS technology to obtain precise information.

The RadSurvey is fully weatherproof and consists of a sodium iodide gamma-ray scintillation detector mounted with a pocket computer and an automatic beacon-corrected GPS receiver with sub-metre accuracy.

It has a long battery life and a built-in multichannel analyser that can be used in the field or the spectra saved and recalled later. During operation, the positional information is displayed onscreen and also stored on a memory card. The data can then be transferred to GIS mapping software to produce contour maps, or classify areas according to user requirements.
