二  主要特点：

   BH3084个人射线剂量仪主要技术指标符合国家标准和国际标准，广泛适用于辐照站、海关、工业无损探伤、核电站、核潜艇、同位素应用和医疗钴治疗等领域。

BH3084个人射线剂量仪是采用新型单片机技术制作而成的智能型仪器，主要用来监测X、γ射线照射人体后人体的吸收剂量。同时该仪器声光报警频率与剂量率成正比，所以也可定性监测剂量率大小

BH3084 DOSE METER

BH3084 dose meter is a intelligent meter which is controlled by a new-style single chip. And it is principal for detecting dose and dose rate of Χ and γ radiation. It can set thresholds. It can send out alarm signal overing the alarm thresholds. It is mainly used in the fields of radiant workstation、CIQ、industry nondestructive flaw detection、nuclear power plant、isotopic application and 60Co radiological medical treatment.

CHARACTERISTICS:

1、Detector: GM counter tube;

2、Energy response:＜±30%（50KeV—1.3MeV）;

3、dose rate response: 0—∞;

4、Measurement range:

Dose rate: 00.01 usv/h—01.00 msv/h;

Dose:    00.01uSv—99.99mSv;

5、Measurement time: 5s;

6、Relative error:＜±20%;(137Cs);

7、dose rate and dose alarm thresholds: set;

8、Battery under voltage indication: it stops working and displays low power;

9、Power supply and Power consumption: two pieces of AA batteries, power consumption＜2mA;

10、Temperature:＜±10%（-10℃～+40℃）;

11、Humidity:＜±15%（95%RH +40℃）;

12、Size: 118Χ65Χ25mm;

13、Weight:＜100g;

OPERATION:

Batteryloading and counting reset:

Open battery box cover and put 2 AA batteries in, it auto rest and display 00.08usv/h.

Change work mode:

setting mode switch, it displays dose rate or dose.

Turn on or turn off power:

Setting power switch ,turning off it turns on, turning on it turns off.

Set:

Setting set switch, it can set thresholds of dose and dose rate. In the mode of setting dose rate, set mode switch can change every number of dose rate. In the mode of setting dose, set mode switch can change every number of dose. In the mode of setting sound, set mode switch can change have sound or no sound.

Self-test

Under background level condition, alarm 30 times every second，it’s good to work.

Meter stops work and displays low power when it is low power. It’s time to replace the batteries and record dose.

DOSE VALUES REFERENCES

1) According to recommendations of ICRP publication 60:

The dose limination of occupational people is following, Effective dose limit is 100 msv for 5 years, average value for one year is 20 msv, the value of 50 msv can not be over for any one year.

Annual dose limitation for residens is 5 msv.

2) Relation formula of irrediation dose and dose equivalent:

1sv=100rem≈100R

1usv/h≈100uR/h
