Principle of Inspection System

ØCobalt-60 source emits γ- ray (1.17MeV, 1.33MeV)

Ø
Fan shaped γ- ray generated by the shutter and front collimator

Øhorizontal angle is 0.1°

Øvertical angle is 65°

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

Ø
Electronic signals are generated afterγ- ray goes through the back collimator and enter the CdWO4 detectors

Øγ- 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

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

Ø
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

ØIG-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:

ØEnergy is invariable (1.17MeV, 1.33Mev, average 1.25MeV)

ØIntensity is quite steady

ØWorking 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

Ø
2. Power support

ØNo need of out power supply

ØNo high-power electric device

ØNo interference of high voltage and microwave

Ø
3. Security protection

ØLittle output of radiation

ØUnified source with its shield vessel and shutter, easy to be protected

ØForbidden area is small that only 6 meters is required

ØThe thickness of protection wall is only 0.4 m

ØBuild site needed is also quite smaller and the costs of construction is lower

Ø
4. Dose

ØThe maximum detection dose is only 0.01mGy

ØIt is so small just as one percent of an X-rays

Ø
5. Price

ØThanks to the low price, the investment of an inspection station is quite lower.

uAdvantages of solid detector

Ø
1. Excellent performance

ØHigh detecting efficiency (80% detecting rate for Co 60 γ- ray)

ØHigh sensitivity, image definition and resolution

Ø
2. Firm material

ØLowest failure rate

ØNo higher voltage and air pressure

ØHumidity-proof, shake-proof

Ø
3. Simplified techincs

ØShort production cycle and easy to make a batch production

ØShort delivery time needed (only 6 months) to meet urgent need of user

Ø
4. Convenient maintenance

ØMulti glittery crystal and relative circuit are assembled in one board

ØConvenient and rapid maintenance only by pulling and plugging electronic boards

Comparison to Competitor - Detector Comparison

ØThe price/performance rate is excellent

Ø
Initial investment are extremely low

Ø
Occupied space of whole system is small

Ø
High working efficacy

Ø
Convenient maintenance, Only normal mechanical and electronical maintenance needed

Ø
Economic Maintenance Charges during operation

Ø
Short production period, 6 months or less delivery time.
