JB4022型χ-γ辐射个人报警仪
JB4022型χ-γ辐射个人报警仪用来监测各种放射性工作场所的X、γ以及硬β射线的辐射，主要应用于辐射监督管理人员、工业探伤、辐照站、放疗医务人员等从事辐照工作人员，能够准确测量辐射剂量以确保工作人员的安全。该仪器可同时测量剂量率与累积剂量，如果超过预设剂量或剂量率值，仪器将振动和发出报警声。探测器为经补偿的GM计数管，故测量范围宽、能量响应好，内置可充电锂离子电池，有过载指示及保护功能。

JB4022 personal warning device for X-γ radiation
Introduction
JB4022 personal warning device for X-γ radiation is used to monitor
X, γ and β-ray radiation in various kind of radioactive workplace. It is mainly
used for personnel engaged in radiation such as radiation supervision
management, industrial radiography, irradiation station and radiotherapy
medical personnel, so that it can accurately measure the radiation dose to
ensure the safety of the personnel. This instrument can simultaneously
measure dose rate and accumulated dose. If the value exceeds the preset
dose or dose rate, the instrument will vibrate and provide acoustic alarm. Its
detector is a compensated GM counter, so this instrument has a wide
measurement range and very good energy response characteristics. The
instrument is provided with a built-in rechargeable lithium battery and the
functions of overload indication and protection
Features
High sensitivity, wide measurement range
Simultaneous display of accumulated dose and dose rate
Singlechip technology, multi-functions and small volume
Easy and convenient operation
Alarm threshold can be preset
Rechargeable lithium battery which can be charged in the computer or
AC power supply through USB port
Battery low voltage alarm
Accumulated dose can be stored for a long period in case of power
failure
With real-time clock function
Alarm modes: sound, vibration, sound+vibration
Color of enclosure: blue, orange
