The Model 971 Food-SSAFE Kit (Spectrum/Sample Analysis and Food Examination Kit) from Berkeley Nucleonics offers non-technical equipment users an easy method for measuring radiation levels found in fish and meat products, liquids and soil samples. The nuclear radiation found in food is measured and reported by a software algorithm coupled with a sensitive NaI (sodium iodide) detector. Food products (beef and poultry, fish, vegetables, water samples or grains) are placed in a Marinelli beaker then insulated with a lead shield. Once the sample is prepared, the shield in place and the NaI detector is correctly orientated, analysis begins automatically.
The data is collected in a small Multi-Channel Analyzer (Model 970) and then processed with a NOMAD micro-PC. The results are displayed on the screen in real time, but can also be stored for future analysis. Users can also recall the reports and send to a label printer for documentation of multiple samples.
The portable system includes all the accessories required for complete analysis in the field. For example, a digital scale, a sieve and a barcode scanner are also included to manage larger applications with many samples. Results from the system are presented in Becquerel / Liter or Becquerel / Kilogram. The entire system packs neatly into a large Pelican-Style hard case with reinforced hinges and wheels. The wheeled case includes a smaller case to house the heavy lead shield; however, a compartment for disposables like plastic bags, plastic containers and sealing tape are also included. The model 970 Food-SSAFE can be commercially shipped and weighs 110Lbs (50 Kgs)
“Food-SSAFE provides a cost effective alternative to High Purity Germanium systems which can be cumbersome to cool in both laboratory or field settings”, comments David Brown, Company President. “Most nuclear measurements of soil and agricultural products are focused on Nuclear Power Plant reactor isotopes. Isotopes like Cesium 137 and Iodine 121 are reasonably easy to measure at very low levels with lower cost sodium iodide detectors.”
Berkeley Nucleonics offers Food-SSAFE as a kit or as part of a larger radiation detection and response program. The company bundles a family of additional personal detectors and identifiers with the kit. A comprehensive training program accredited by several industry agencies is also offered.
