Startup
Prepare two No. 5 batteries; upon battery installation, the instrument sends out a “beep” and LCD shines; once the instrument has installed the batteries, press [Switch/power] key for 3 seconds–the instrument starts up and LCD displays the following figure:

(Figure 2)

Shutdown
Press [Switch/power] key for 3 seconds; the instrument sends out a “beep” and the instrument is shut down.

Measurement
The instrument enters into the measurement status upon startup; during the measurement, it can place in the hand, pocket and backpack. The instrument has two measurement values: dosage rate in the unit of u Sv/h, u Gy/h and m R/h; accumulative value of dosage rate within a certain period of time: accumulative dosage in the unit of u Sv or m Sv. Once any measurement value exceeds the setup alarm valve value, the instrument sends out alarm according to the setup alarm mode.

Specification of LCD display data

The instrument can display the following information:

(Figure 3)

In case of inadequate power supply voltage, the battery under-voltage indication sign displays and blinks.

Under normal condition, Err sign does not appear; permanent appearance of Err sign means damage of Geiger counting pipe detector.

Conversion knowledge of radioactive units

International standard (China is in strict adherence to this standard) 1990

1. Radioactive work personnel: 20 mSv/year (10 Sv/hour) 2. General personnel: 1 mSv/year (0.52 Sv/hour)
   Remark: The above stipulations are in strict adherence to relevant suggestions of ICRP and basic standard of China’s radioactive sanitation protection (GB–4792–84).

Unit conversion knowledge:
1Sv/h=100R/h

1 n Ckgh-1/h = 4 R/h 1R/h = 1 r (the unit of original nuclear industry in the mine exploration process)

Radioactive activity :
1 Ci = 3.7 X 1010 Bq = 37 GBq 1 m Ci = 3.7 X 107 Bq = 37 MBq 1 Ci = 3.7 X 104 Bq = 37 KBq 1 Bq = 2.703 X 10-11 Ci = 27.03 pci

Irradiation dosage:
1 R = 103 mR = 106 R 1 R = 2.58 X 10-1 C kg-1

Absorption dosage:

1 Gy = 103 mGy = 106 Gy
1 Gy = 100 rad
100 rad = 1 Gy

Dosage equivalence:

1 sV = 103 m Sv = 106 Sv
1 Sv = 100 rem
100 rem = 1 Sv

Others :

1 Sv is equivalent to 1 Gy. 1 Clay = 0.97 Ci 1 Ci

Radon unit: 1 Bq/L = 0.27 em = 0.27 X 10-10 Ci/L

Calculation of decay value of radioactive isotope

A = Aoe-t
= 1 n2/T1/2
T1/2 means semi-decay period;
Ao means strength of known source;
A means strength upon time period t.

Please search for the radioactive decay calculation form and calculate the radioactive screen:

1/2 and 1/10 of difference substance (cm)

Radioactive| Lead| Iron| Concrete
source| | |
| 1/2| 1/10| 1/2| 1/10| 1/2| 1/10
Cs—137| 0.65| 2.2| 1.6| 5.4| 4.9| 16.3
Ir—192| 0.55| 1.9| 1.3| 4.3| 4.3| 14.0
Co—60| 1.10| 4.0| 2.0| 6.7| 6.3| 20.3

Relationship between radioactive source and distance:
The strength of radioactive source is in inverse proportion to the square of distance. X = A. r/ R2 A: Radioactive activity of spot source; R: Distance with source; r: Constant figure of illumination rate.

Remark:

Ra—226 (t = 1608 years) r = 0.825 Lun. m2/hour. Curie
s – 137 (t = 29.9 years) r = 0.33 Lun. m2/hour. Curie
Co – 60 (t = 5.23 years) r = 1.32 Lun. m2/hour. Curie
