radiation with low-energy and intensity from
video display units, night vision devices,
oscillographs, TV receivers, microwave
emitters, ion implanters, search and
medical continuous X-ray apparatus
▪ Certification testing of instruments and
equipment with sources of unused X-ray
radiation, protective measures
management

55

Fe, 239Pu, 109Cd, 125I, 129I, 241Am, 57Co, 139Ce

etc. isotopes.

Unique highly-sensitive devise for measuring radiation exposure on

Features
▪ Search for X-ray and low-energy gamma
radiation sources

crystalline lens, mucus membranes and skin.

Measures directed dose equivalent rate of continuous X-ray radiation with
energy from 5 keV.

▪ Quick accommodation to changes in
radiation level
▪ Sound and visual alarm in case threshold
level is exceeded
▪ Memory function for 100 measurement
results

Operating principle
NaI(Tl) ø9x2 mm scintillator with beryllium window is used in the dosimeter
as an X-ray detector.

Method of measuring directed dose equivalent rate is based on determining
of instrument spectrum and its non-continuous weighing with normalization per
dose rate unit, while the energy dependence is corrected.

▪ Integrated system for measurement path
LED stabilization, so there is no need for
check radioactive source
▪ Analogue-to-digital converter foe 256
channels
▪ Measurement results can be written, stored
and transmitted into PC using RS 232
interface
▪ Dust and splash-proof design
▪ Not for natural background measuring
▪ Background component correction during
measuring
