DOSIMETER SMG2

 

radiation monitor which is a modern multifunctional household device designated for assessment of an ambient beta-, gamma- dose radiation equivalent rate (of food stuff, construction materials, earth) by people in domestic conditions. This appliance can also be used by personnel dealing with ionizing radiation sources. Taking into account various needs of our customers, SMG 2 dosimeter features wide range of customized settings.
