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.
It features an automatic failure detection function and measures x, gamma, and beta radiation dose rates from background to elevated levels
The digital LCD display includes backlighting and specifies measurements in various units
Alerts for low battery levels, measurement errors, surface soft and hard beta-particle flux density, threshold levels, and real-time data
Incorporated with a magnifying tube enables quick detection and localization of gamma and beta radiation sources within seconds
Equipped with a built-in gamma and beta-sensitive Geiger-Muller counter, enhancing its sensitivity to these types of radiation
Automatically sets intervals and ranges, saves dose values, and detects failures for increased reliability
Customizable multiple alarm response including voice and dose rate alarms with adjustable cumulative dose thresholds, instant light, and vibration activation
It includes ore-containing materials for detecting radioactive substances and a cobalt source for electronic accelerator radiation detection
