Principle of Inspection System
 
Cobalt-60 source emits γ- ray (1.17MeV, 1.33MeV)

Fan shaped
γ- ray generated by the shutter and front collimator
horizontal angle is 0.1
vertical angle is 65

Y- ray penetrates the goods in a container, a part of its energy is absorbed while others penetrates through the container

Electronic signals are generated after
γ- ray goes through the back collimator and enter the CdWO4 detectors
 
γ- ray energy absorbed is related to the absorptivity (weight, thickness) of the goods in a container, materials with high density and atomic number have strong capability of absorption

A scan line can be displayed on the screen by collecting and processing the signals outputted by detectors

A two dimensional perspective image can be viewed with the scan lines displayed one by one while
the moving container is scanned by the fan shaped γ- ray

Main Advantages of Inspection System
 
uCombination of Cobalt source and solid detector
 
IG-SCAN-2000 is the embodiment of both the advantages of Cobalt source and solid detector
u
Advantage of Cobalt-60 γ source

1. Main characters:

Energy is invariable (1.17MeV, 1.33Mev, average 1.25MeV)
Intensity is quite steady
Working status of source does not need adjustment, monitoring and maintenance γ- ray shutter is opened by electromagnetic power and shut automatically when power off  Costs of running and maintenance is much lower

2. Power support
No need of out power supply
No high-power electric device
No interference of high voltage and microwave

3. Security protection
Little output of radiation
Unified source with its shield vessel and shutter, easy to be protected
Forbidden area is small that only 6 meters is required
The thickness of protection wall is only 0.4 m
Build site needed is also quite smaller and the costs of construction is lower

4. Dose
The maximum detection dose is only 0.01mGy
It is so small just as one percent of an X-rays

5. Price
Thanks to the low price, the investment of an inspection station is quite lower.

 

uAdvantages of solid detector

1. Excellent performance
High detecting efficiency (80% detecting rate for Co 60 γ- ray)
High sensitivity, image definition and resolution

2. Firm material
Lowest failure rate
No higher voltage and air pressure
Humidity-proof, shake-proof

3. Simplified techincs
Short production cycle and easy to make a batch production
Short delivery time needed (only 6 months) to meet urgent need of user

4. Convenient maintenance
Multi glittery crystal and relative circuit are assembled in one board
Convenient and rapid maintenance only by pulling and plugging electronic boards

 

Comparison to Competitor - Detector Comparison

 

The price/performance rate is excellent

Initial investment are extremely low

Occupied space of whole system is small

High working efficacy

Convenient maintenance, Only normal mechanical and electronical maintenance needed

Economic Maintenance Charges during operation

Short production period, 6 months or less delivery time.
