FOODGUARD Food/Water Rapid Measurement Gamma Spectrometer

Food/Water Rapid Measurement Gamma Spectrometer

Product introduction           

• The FoodGuard-1 Sodium Iodide Food Screening System is designed for rapid screening of radioisotope-contaminated solid and liquid foods.

• Facilitating "frontline" rapid response for food producers, traders, import and export agents, etc., FoodGuard-1 is an out-of-the-box solution designed to start up and test samples in minutes.

• The FoodGuard-1 food monitoring system can quickly and accurately screen food for radionuclides caused by nuclear power plant release events: eg 131I, 103Ru, 134Cs and 137Cs. Total cesium (sum of 134Cs and 137Cs activity) can also be reported.

• The system is battery powered, portable, and low power consumption, so it can be used in places where food is collected, imported, sold, or consumed. It is easy to carry and the optional trolley makes the system easy to use in places such as food markets for convenient inspection of food products.

Features

• Efficient counting and easy sample loading in a benchtop lead shield using a 3" x 3" NaI radiation detector.

• The digiBASE is connected via USB for easy assembly and contains all necessary electronics: small preamplifier and detector high voltage power supply, powerful digital signal processing and multichannel analyzer.

• Intuitive software display, high degree of automation and results storage or printing.

• Calculated results such as Maximum Permissible Concentration Percentage (MPC).

• Immediate feedback with an audible alarm to warn of sample activity exceeding a user-set MPC limit percentage.

• Light enough to be transported to the point of use, such as the entrance of a food market.

• Factory pre-calibrated for use directly with sample containers and check sources.

Advanced version FOODGUARD-2 (High Purity Germanium Detector) version Food Fast Water Meter available. The FoodGuard-2 Workstation is an out-of-the-box system that meets the needs of institutions that need to accurately quantify radionuclide content in food. By using a high-resolution high-purity germanium (HPGe) radiation detector, each gamma-ray-emitting radionuclide in the sample can be quantified as a specific activity in Bq/Kg or Bq/L. FoodGuard-2 is specifically designed for agricultural monitoring with an intuitive software interface for quick and clear results from test setup
