FoodGuard-2

HPGe workstation for quantitative determination of radionuclides in food

Complete workstation for measuring gamma-emitting radioactive contaminants in food, water and other agricultural samples after an accident or terrorist incident. With a high-resolution HPGe detector, every gamma-emitting radionuclide is quantified as specific activity in Bq/kg or Bq/litre. An administrator sets up sample types, alarm limits and reports, after which the operator just enters the sample information and starts counting.

AlarmConfigurable alarms when activity level, percentage or sum of activities is exceeded; editable limits tables derived from international standards (examples from e.g. the US FDA and WHO)1
ReportingCustomizable reports in HTML and PDF format1
CalibrationSupplied pre-calibrated with a ⁴⁰K check source1
Cs-137 MDC0.75 Bq/L in 10 minutes; 0.5 Bq/L in 30 minutes (20% detector, 2-litre Marinelli beakers of liquid; calculated using ISO 11929); lower with larger detectors and longer count times2
