The Ludlum Model 4404-16 and 4404-16-4 Geo-Exploration Systems provide radiation surface measurements to help discern zones of interest in the underlying geology of a targeted area. These instruments serve as excellent oil exploration and ore prospecting tools. Their high sensitivity also facilitates large area surveys when looking for radioactive contamination.

Each system is comprised of a large scintillation detector, multi-single-channel electronics, and a waterproof enclosure. The Model 4404-16 has a large 5.1 x 10.2 x 40.6 cm (2 x 4 x 16 in.) NaI detector, while the Model 4404-16-4 has a 7.6 x 7.6 cm (3 x 3 in.) NaI detector. The Model 4404-16-4 also has a wireless transceiver for cable-free data transfer, a rechargeable battery, and a compact carrying case that can easily fit into a moderately-sized backpack (not included).

A computer is required to read data from the instruments. Ludlum offers a ruggedized computer as an option, or the customer may provide their own computer. A GPS option is also available to help easily relocate points of interest. Contact Ludlum Measurements for more information about these options.

Each instrument includes the Geo-Explorer PC software. The software displays the radiation data just like a chart recorder and logs the radiation data along with its corresponding GPS coordinates into a comma delimited file. The accompanying “KML Generator” software program converts the data files into files suitable for viewing in Google Earth™ or any other 3D earth browser implementing the KML encoding.
