Detection and measurement of radiation in food

Equipment for measuring levels of radioactivity in foodstuffs and liquids, combining easy-to-use interface for non-expert users, with fast an accurate response to compare radiation levels with international standards.

Bioscout radiation in food monitor

Bioscout radioactivity in food monitor The BioScout radiation-in-food detector offers the possibility of making immediate tests for radioactive contamination on-site without specially skilled staff. Training in the use of the Bioscout takes a few minutes; the user places the food sample in a beaker, places the beaker in the monitor, and presses a button. The Bioscout detector fits onto any table andd surface and can be handled intuitively. The robust and ergonomic design allows easy cleaning if necessary, thus is suitable for use in foodstuffs areas. There is no need for shielding against background radiation by heavy lead or steel elements. The internal scale enables the direct calculation of the weight related activity including the sample density correction. A large Sodium Iodide (NaI) detector and the optimized sampling geometry in combination with an advanced spectrum analysis result in short sampling periods and a high sample throughput.

PM1406 radiation in food monitor

PM1406 radioactivity in food monitor

The most economical radioactivity-in-food monitor on the market, the PM1406 consists of a high sensitivity CsI scintillation detector, and a set of plastic beakers (Marinelli-type). A well inside the beakers fits neatly over the detector, thus placing the detector within the food volume to maximise sensitivity. The detector itself connects to a desktop PC or laptop via a USB cable; the PM1406 software provided with the device allows quick and easy identification of food radiation levels in terms of Bq/kg or Bq/l, also data storage. The device is especially useful for non-expert users with no knowledge of radiation, and ideal for use in the home, shops, restuarants, etc. If the food is heavily contaminated the measurement takes a few minutes. At lower contamination levels, more time is required for defining radionuclide specific/volumetric activity. Optionally, the PM1406 food radiation detector can be supplied with a lead outer container to increase sensitity by eliminating natural background radiation from the readings. Minimum threshold activity at using lead shielding is 10 Bq/kg. Radionuclide activity level is registered, analyzed and compared with food radioactive contamination limits set in accordance to international and national Standards. With an internet connection and user registration, libraries of permissible radionuclide contamination level are updated automatically via Internet.
