FJ34-5302 Digital Handheld γ Nuclide Recognition Spectrometer
Product Introduction
FJ34-5302 Digital Portable γ The spectrometer is a nuclear monitoring instrument based on a
brominated lanthanum detector and advanced digital nuclear pulse
waveform processing technology. This instrument integrates a
lanthanum bromide detector and a neutron detector, which not only
provides environmental dose equivalent detection and radiation
source localization, but also identifies the vast majority of
natural and radioactive nuclides. Its function and performance are
comparable to the mainstream portable nuclide recognition
instruments abroad, breaking the trend of relying on similar
instruments in the past.
This instrument is lightweight and aesthetically pleasing, with
high reliability. It is equipped with a large pixel,
environmentally friendly and energy-saving LCD color touch display
screen. The human-computer interaction is simple and convenient,
making it easy for operators to carry it with them and conduct
real-time inspection of product standards.

Instrument installation
In war environments, this instrument can be used as an on-site
nuclide screening analyzer, such as nuclear waste disposal site
nuclide analysis, nuclear leakage accident site radioactive
pollution monitoring, etc., to obtain the required results on site.
The measured data can also be saved through computers for deeper
analysis and processing, in order to obtain more detailed results.
At the same time, it can also serve as a laboratory radionuclide
analyzer for measuring the collected samples. This instrument is
one of the best instruments for nuclear radiation supervision,
inspection, and monitoring institutions, as well as nuclear
emergency response units, to address potential hazards in the
current development of nuclear technology.
In a war environment, this instrument can be used as a on-site
monitoring instrument for nuclear warfare or radiation contaminated
areas to determine the main types of radioactive nuclides and the
severity of contamination on site, in order to provide a scientific
basis for taking further related actions
