Food Contamination Monitor PM1406

РМ1406 Food Contamination Monitor is intended to measure the radionuclide activity in food and liquids. Instrument measures specific (for solid and dry substances) or volumetric (for liquids) activity 137 Cs +134 Cs + 40 К nuclides in the sample. Instrument also enables permanent or periodic radiation monitoring of the ambient radiation background.

Operation Principle

Food contamination monitor PM1406 is a high-sensitive detector for measuring radionuclide specific and volumetric activity in food. CsI(TI) scintillation crystal is used as a detector.  Marinelli Beaker (0.5 l. volume) is directly fixed on the detector so that it is surrounded from all the sides therefore the maximum measurement effectiveness is achieved.

Contamination control is made by measuring radionuclide activity of 137Cs and 134Cs which are most likely to get in food after technogenic radiation accidents as well as 40K, which exists as natural radioactive nuclide in the environment.

Measurement results processing and information output are made while PM1406 monitor is connected to PC via USB. Along with the device special software package is supplied, which is designed for detector control, device settings input, as well for the display and storage of measurement results. User-friendly interface makes the device easily applied in household use for everybody with any level of radiation control knowledge and computer skills. The delivery set includes the detector and Marinelli Beakers for food samples.

The device is of high environmental stability and resistance. Marinelli Beakers for food sample are easily detached and ready for dishwashing machine. Special container provides comfortable and compact storage.


Software provides the user with information whether food product is clean or contaminated. The received information allows the user to decide on whether to use the food or not.

Radionuclide activity level is registered, analyzed and compared with the food radioactive contamination limits, that are set in according to international and national Standards (hygienic regulations, sanitary guidelines and so on). The user can choose the necessary regulatory Standard.

Flexible individual parameter setting helps to create user’s own most frequently used food types pattern libraries with fast and easy interface language and measurement units change. Software allows storing measurement results for further screening and analysis.
