Cargo inspection by means of electromagnetic radiation

Sammanfattning: This study is based on a detailed literature review of the approaches that are being used for inspecting cargos. It was concluded that especially X-rays are suitable for precise inspection of cargos due to high-quality output images. The images captured with X-Ray scanning methods are sufficient for discriminating various materials. Methods for the inspection of cargos with the help of electromagnetic radiation at radio frequencies are also discussed.
