Containerised cargo screening

The seaborne and land-transported containerised cargo supply chain is as accessible as it is ubiquitous and therefore represents one of the most significant threats to border security.

Approximately 90% of all international non-bulk cargo is transported in standardised shipping containers. Over 30 million containers make more than 250 million point-to-point movements each year. However, most countries screen less than 5% of containers passing through their ports leaving their border exposed to the importation of explosives, drugs, nuclear material and other illicit trade.

Cargo containers are screened using a wide variety of technologies. High energy radiation screening technologies (x-rays, gamma-rays or neutrons) are able to penetrate the container and its cargo. Radiation detectors then stitch together multiple “slices” through the container to build up an image of its contents. In this manner it is possible to “see through” sealed shipping containers, detecting and identifying contraband material.

The current generation of cargo screening technology is limited to a container throughput of up to 20-30 containers per hour. Consequently the cost per container scanned is prohibitively high and only the very highest priority containers are scanned. In busy ports multiple installations are required frequently to ensure that even the most basic level of cargo screening can occur.

Benefits of SITORO to containerised cargo screening

Southern Innovation’s  SITORO technology dramatically improves detector efficiency. Consequently, the throughput of container screening installations can be significantly increased, driving down the screening cost per container and significantly increasing the percentage of containers that can be screened.
