Purpose and Characteristics

1BH3103B is a portable chi gamma dose rate measuring instrument. Mainly used for the environment

Measurement of Air Absorption Dose Rate of Radiation X - γ. Radioactive monitoring of various building materials, industrial radioactivity

Radiation monitoring, dose monitoring in workplaces with gamma radiation sources, dose monitoring around X-ray machines, nuclear power

Radiation monitoring for stations, geological mines, medical and health departments, etc.

2Advantages: The instrument works stably and reliably, has high sensitivity, good energy response and angular response, and can measure

Wide range, good cosmic ray response, powered by rechargeable batteries, lightweight, and easy to carry.

3Improvement features: This instrument adopts LCD large screen LCD display, Chinese menu prompts for operation, and communication

Automated measurement can be achieved by setting measurement parameters, and the system has real-time clock, power-off data storage, and battery

Functions such as low battery alarm, dose rate over threshold alarm, data query, printing, etc. Easy to operate and convenient to use.

Main technical performance

1Energy response: 25KeV~3MeV, with a variation limit of ± 15%

2Cosmic ray response: The limit of variation is ± 15% (relative to the RS-111 ionization chamber)

3Range: (1~10000) × 10^-8Gy/h

4Inherent error of dose rate indication: not greater than 10%

5Angle response: using¹³⁷The limit value of Cs source variation from 0 to 150 ℃ relative to the maximum response value shall not exceed 15%

6Under normal working conditions, the limit for the variation of the displayed value after 8 hours of continuous operation is ± 7%

7Environmental temperature for use: (-10~+40 ℃) with a variation limit of ± 30%

8The power consumption of the instrument is about 400mW, powered by Ni-H rechargeable batteries, which can be used intermittently for 50 hours (up to 4 hours of continuous use)

Or use continuously for more than 24 hours.

· BH3103BMainly used for measuring the absorbed dose rate of environmental radiation in the air. Radiation monitoring of various building materials, industrial radioactive radiation monitoring, dose monitoring of workplaces with X-ray radiation sources, dose monitoring around X-ray machines, radiation monitoring of nuclear power plants, geological mines, medical and health departments, etc.
