FoodGuard-2-AK adds kit for high-resolution germanium gamma spectroscopy workstation

ORTEC FoodGuard 2is a quantitative solution for the determination of food radioactivity via high-resolution gamma spectroscopy with a high-purity germanium detector. It is designed to simplify and simplify sample handling in busy laboratory environments. theFoodGuard-2-AKAdd-on kits are easy to install and add-on to anyORTECGamma spectroscopy systems have been usedGammaVisionsoftware. without affectingGammaVisionWith the system running, it can be installed in minutes and, once calibrated, provides users with standardFoodGuard-2full functionality of the system. This greatly simplifies operation.

The resulting workstation is a ready-to-use, fully functional system that enables sophisticated analysis of food, water and other agricultural products that contain radioactive materials that may produce any form of gamma ray emission following an accident or incident.

FoodGuard-2Workstation software included from international regulatory organizations(such as the U.S. Food and Drug Administration and the World Health Organization)acceptable radionuclide activities(Such as¹³⁷Cs、¹³⁴Csand¹³¹I)An example of a restriction table. These tables can also be customized with additional nuclides and different limits to meet your specific needs.

in order to makeFoodGuard-2With the system running, supervisors can calibrate, set sample types, alarm limits and report outputs in just a few simple steps. For regular“High sample throughput”To use, the operator enters some key sample information using an interactive user interface, places the sample in one of the included marlin cups, and begins counting.

During the count, the software provides feedback such as energy spectra and alarm notifications, then presents a professionally formatted report that can be shared or archived. The purpose of this operation is for high sample throughput and clear results.

FoodGuard-2-AKAdd-ons include6a2liter of marin sample cup and a check source, including a2Liter full(⁴⁰K)Marin Cup. This beaker is suitable for end cap diameters less than or equal to83mmHPGedetector.

In addition to sample containers and inspection sources,FoodGuard-2-AKAdd-on package includes two software projects:

• FG-2-B32 FoodGuard-2 Software version1.0.11or higher.
• 797230 Connection upgrade kit version7.02.03or higher.
