Dosimeter LMDOM-A100


Dosimeter LMDOM-A100 is specially designed for measuring and monitoring the cumulative exposure of x-ray, β, and γ radiation over a period of time and provides accurate data on the amount of radiation absorbed by an individual or an object. This dosimeter covers energy ranges from X-ray and gamma radiation, spanning from 40 KeV to 3.0 MeV, as well as beta radiation ranging from 0.5 to 3.0 MeV.
