FJ-3505 Personal Radiation Alarm Dosimeter
Main introduction
FJ-3505 is a multifunctional χ γ radiation dose real-time measuring
instrument with halogen GM counter tube as the detector. It is
designed to be worn on the human body to measure the personal dose
equivalent HP (10), and it can also be used for radiation field
survey and detection. User can set own alarm threshold by FJ-3505.
Technical parameter
| Detector | GM tube detector with energy compensation |
| Energy response | 40keV-1.3MeV |
1. Highly sensitive detector, strong anti-interference ability
2. Can be expanded into a series of products, equipped with wider
range, higher sensitivity and other models
3. Alarm function: There are alarm functions such as dose rate,
cumulative dose, working time, etc., and the alarm threshold is
continuously adjustable
4. Data transmission: the measurement data can be transmitted to
the computer through the data cable (optional)
5. Alarm threshold can be set by user
6. Measuring range:
Dose equivalent rate: Hp(10) 0.1 μSv/h-100mSv/h
Cumulative dose equivalent: Hp(10) 0.0 μSv-99.99 mSv
Cumulative dose equivalent response error: within the range
<±15% (137Cs)
7. Energy response: meet GB/T13161-2015 national standard
requirements
8. Power consumption: the power consumption of the whole machine is
less than 2mW, and the continuous use time of two AAA alkaline
batteries is more than 700 hours
9. Temperature and humidity characteristics: at -10℃--+50℃, the
error is ≤±10%; under 35℃, humidity 0-95%RH (+35℃) error ≤±10%
Application
It is suitable for the protection and personal dose monitoring of
workers in radioactive applications such as industrial
non-destructive testing, isotope applications, nuclear industry,
hospitals, railways, civil aviation, and environmental protection.
