A ug 2 00 7 Detection of Neutron Sources in Cargo Containers
We investigate the problem of detecting the presence of clandestine neutron sources, such as would be produced by nuclear weapons containing plutonium, within cargo containers. Small, simple and economical semiconductor photodiode detectors affixed to the outsides of containers are capable of producing statistically robust detections of unshielded sources when their output is integrated over th...
متن کاملRecent Developments in Fast Neutron Radiography for the Interrogation of Air Cargo Containers
There is a growing need to rapidly scan bulk air cargo for contraband such as illicit drugs and explosives. Ideally, cargo containers must be imaged without unpacking and with scan times of less than one minute. Fast neutron techniques are particularly attractive for screening cargo as they can be used to determine cargo composition. The Commonwealth Science and Industrial Research Organisation...
متن کاملA ug 2 00 7 X - Radiography of Cargo Containers
The problem of detecting a nuclear weapon smuggled in an ocean-going cargo container has not been solved, and the detonation of such a device in a large city could produce casualties and property damage exceeding those of September 11, 2001 by orders of magnitude. Any means of detecting such threats must be fast and cheap enough to screen the millions of containers shipped each year, and must b...
متن کاملCompressed Sensing Techniques Applied to Ultrasonic Imaging of Cargo Containers
One of the key issues in the fight against the smuggling of goods has been the development of scanners for cargo inspection. X-ray-based radiographic system scanners are the most developed sensing modality. However, they are costly and use bulky sources that emit hazardous, ionizing radiation. Aiming to improve the probability of threat detection, an ultrasonic-based technique, capable of detec...
متن کاملIs Screening Cargo Containers for Smuggled Nuclear Threats Worthwhile?
In recent years, Customs and Border Protection (CBP) has installed radiation sensors to screen cargo containers entering the United States. They are concerned that terrorists could use containers to smuggle radiological material into the country and carry out attacks with dirty bombs or a nuclear device. Recent studies have questioned the value of improving this screening system with new sensor...
