1. Functional oveiew

Radiation individual alarm device is collocated with highly exible

Geiger counting pipe as detector;it is mainly responsible for

monitoring the radiation of X, y and hard β ray in various radioactive

work areas; it is featured as swift response and broad measurement

scope; It is able to display the dosage equivalent rate it is widely

applied in the individual safety protection monitor and

radioactive indication for work personnel in the following

elds:nuclear power plant, accelerator, iron & steel indust, chemical

indust, isotope application, industrial X and y non-destructive aw

detection, radioactive medical treatment, Cobalt soure treatment, y

radiation, radioactive laborato and surrounding environment

monitor of nuclear facilities.

5.Optional alarm modes including sound/vibration.

3.Technological Parameters

1.Radiation Detection: X, gamma and hard betarays

2.Detector: energy compensation GM tube(Geiger counter tube)

3.Normal content standard within 0.5μs V/h

4.Measurement range

Dose equivalent rate: 0.00-1000uSV/h(maximum 10mSv/h)

5. Energy range: 48 ke V-1.5 MeV ≤±30% (for137Cs-)

6.Sensitivity: 80 CPM /μSw/h(for Co-60)

7. Measurement display: the dose rate display will update eve

second and the protect alarm display is shoer than 5 seconds.

8.Operating environment: temperature -10℃

~+45℃. Relative humility:≤95%(+45℃)

9.Dimensions:143×77×28mm

4. General Operation Method

1.Staup

Prepare 2 AA batteries; Since with batteries installed, press and hold

【O】button for 3seconds and the instrument will sta up. TheLCD

display is as the following gure:

5. Parameter setting

The parameters that can be modied by the user include: system time,

system information, automatic shutdown, and language setting. The

corresponding parameters can be modied through the keyboard.

Alarm Settings

1)Shutdown

Press and hold 【O】 button for 3 seconds,

and the instrument will shut down.

2)Measurement

The instrument will be in measurement mode since staup. There are

two measurement values: one is dose rate with units of μSv/h,uGy/h,

mR/h, cps and cpm;the other one is accumulated dose,which is the

accumulative value of dose rate for some time, with units of μSv or

mSv. The instrument will ring an alarm as the preset alarm mode when

a type of value exceeds the set alarm threshold.

3)Refresh: Press the 【O】 key to resta the device for testing.

4)Alarm settings: audible alarm, vibration alarm

5)Instructions for LCD Display Data This information displayed on this

instrument is as follows:

6、 Conversions

I. International standard(our count implement this

standard) 1990

1.Radioactive sta: 20mSv/a

2.General Public: 1mSy/a

Note: the standard above is according to ICRP

suggestions and GB-492-84 regulations.

II. Knowledge for Unit Conversions and Etc

IsV/h=100R/h

InCkg-1/h=4μG/h

Radon Unit: 1Bp/L＝0.27em＝0.27x10^(-10)

III. Calculation for Decay Value of Radioactive

Isotopes

A=A0e﹣λτ 1=1n2/T1/2

T1/2 is half-time period

A0 is the known source strength

A is the strength after the time of t

9, Notice

Radiation individual alarm is a precise

instrument. Please protect it carefully. The following suggestions are

for the maintenance and life extending of the instrument.

a、Keep it dries as much as possible in the process of storage and use,

and too much moisture will cause the instrument damage.

b、Do not drop. knock or severely shake the detector, or it will cause

damages of this detector.

c、Remove the batte when the instrument is not used for a long

period of time. If the instrument dose not work properly.

The company resees the right to theimprovement of product

peormance ormodication of the manual without priornotice to

users.

10、 Safe Operation Norms

Please read the manual carefully. Itmay cause the improper working of

the instrument if the user doesn't operate following the manual.

IV.Relationship between Radioactive Resource and Distance

The strength of the radioactive source is ininverse propoion of the

square of the distance.

X= A.r/R2

A:the activity of point radioactive source;

R: the distance to the source;

r: the constant of exposure rate

1μR/h=lγ(the former used unit for mineral

search of nuclear indust)

Radioactivity:

1Ci=3.7x 10^10Bp=37GBq

ImCi=3.7x10^7Bp=37MBq

1Ci=3.7x10^4Bp=37KBq

1Bp=2.703x10^(-11)Ci=27.03pci

Dose equivalent:

ISv= 10^3mSv=10^6μSV

I Sv=100rem

100urem=lμSy

Exposure Dose:

1R=10^3mR=10^6μR

1R=2.58×10^(-4)Ckg -1

Absorption Dose:

1Gy=10^3mGy=10^6μGy

1Gy=100rad
