X-RAY RADIATION DOSIMETER AT-1103M

Unique high-sensitive instrument to control dose burden of crystalline lens, mucous membranes and skin. It measures directional dose equivalent rate of continuous x-ray radiation with the energy from 5 keV

Features

- X-ray source search
- Fast response to radiation background change
- Audible and visual alarm at threshold exceeding
- Large digital backlit LCD with analog scale
- Keeping up to 100 measurement results in the dosimeter nonvolatile memory
- Built-in LED stabilization system providing no need to use a reference source
- 256-channel MCA
- Logging and transferring measurement results to PC
- Dust and splash-proof case
- Three power types

Application

- Control of acceptable low-energy and intensity x-ray levels from video monitors, night vision equipment, oscillographs, TV receivers, microwave generators, ion implantation devices, inspection and medical sets
- Certification testing of instruments and equipment containing unused x-ray radiation sources, safeguards effectiveness control
- Dosimetry contamination control of radioisotopes 55Fe, 239Pu, 129I, 241Am etc.

The dosimeter has scintillation NaI (Tl), ø 9x2 mm, with beryllium window as a x-ray radiation detector. The measuring method of directional dose equivalent rate is based on measuring the instrument spectrum and its interval standardized weighing per a dose rate unit. The relevant energy response correction for the count rate mode is also provided.
