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

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.
