12、外形尺寸:118(長)Χ65(寬)Χ25(厚)mm;
13、重量:<100克;
五、使用方法:
打開電池盒蓋,電池按正負(fù)極性裝入盒內(nèi),儀器自動(dòng)復(fù)位并顯示00.08 uSv/h。
按模式鍵可切換顯示劑量當(dāng)量和劑量當(dāng)量率。
在開機(jī)狀態(tài)下按電源鍵數(shù)秒可關(guān)機(jī),在關(guān)機(jī)狀態(tài)下按電源鍵數(shù)秒可關(guān)機(jī)。
按設(shè)置鍵可進(jìn)入設(shè)置狀態(tài),首先設(shè)置劑量率閾值,按模式鍵可修改各位數(shù)字,按設(shè)置鍵進(jìn)入下一位設(shè)置。按六次設(shè)置鍵可設(shè)置劑量當(dāng)量閾值,同設(shè)置劑量率閾值,按模式鍵可修改各位數(shù)字,按設(shè)置鍵進(jìn)入下一位設(shè)置。按11次設(shè)置鍵可進(jìn)入設(shè)置有無聲狀態(tài),按模式鍵可選有聲或無聲。設(shè)置完有無聲再按設(shè)置鍵可回到工作狀態(tài)。
在自然本底條件下,每分鐘響20~30次,證明儀器正常。
- 電力不足時(shí),儀器停止工作,液晶有“缺電”字樣閃爍,這時(shí)應(yīng)更換電池并記錄劑量值。
六、參考:
放射性職業(yè)人員劑量限值為:有效劑量5年100msv,平均每年20msv,但任何一年不能過50msv。
居民的劑量限值為:每年為5msv(如果連續(xù)五年平均值不過5msv,個(gè)別年度可以略高)。
- 照射劑量與劑量當(dāng)量之間關(guān)系可用下式表示:
1sv=100rem≈100R
1usv/h≈100uR/h
BH3084DOSE 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.

Battery loading 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
