DETERMINATION OF GAMMA ACTIVITY IN FOODS WITH EASE
Ensuring food and its ingredients are safe to eat and meet international limits has become increasingly important after nuclear accidents, such as Fukushima in 2011 and Chernobyl in 1986. The Becquerel Monitor LB 201 reliably detects gamma activities in food samples, liquids and smaller bulk goods.
From switching on the device to the result of the measurement is just a few steps. The simple software of the evaluation unit guides even users without prior knowledge to the measuring result with ease. Thereby, the use of a Marinelli sample cup made of plastic ensures a consistent measuring geometry.
The LB 201 comes with a tailored aluminum case in which all the device parts find space.
Thanks to the modular design consisting of two separate units, the LB 201 adapts perfectly to your workplace.
Therefore, the transport and the flexible application of the LB 201 is ensured.
The use of a Marinelli sample cup ensures a consistent measuring geometry. The plastic cup is ready for food samples, liquids and smaller bulk goods.
The automatic 40K suppression helps with achieving a more reliable result. A second energy window is implemented in order to subtract the influence of the high energy gamma emitter from the measurement result.
