Gamma Spectrometry Kit with 2x2" NaI(Tl) Detector

This kit is a great for professionals and serious hobbyists, it includes a 2x2" NaI(Tl) detector, the latest GS-PRO-V5 driver, all cables and a water resistant ABS instrument case for proper storage.

Setting up is easy, with most users able to download software and produce their first gamma spectra in less than an hour. The GS-PRO-V5 connects to any PC or mac and has been pre-configured and adjusted to work straight out of the box. Minor fine tuning for optimum performance can easily be done once the user becomes familiar with the functions. Free after sales support if required.

The 2x2" detector has better efficiency than the smaller 1.5" meaning it will produce more counts in the high energy region and allows the user to carry out a number of fascinating experiments, both as a count rate meter and as a multi channel peak analyser for most common isotopes. With additional lead shielding (not supplied) this system can detect trace amounts of radioactive contamination in food and soil samples.
