Scanning machines are often used to scan objects for the purpose of inspecting the scanned objects. Known scanning machines, such as the one disclosed in U.S. Pat. No. 4,020,346, include a conveyor to lead an object to be inspected into a scanning chamber where the object is subjected to radiation. A lead curtain is provided at an entrance and at an exit of the scanning chamber to contain the radiation within the chamber while allowing the passage of the object when it is conveyed in or out of the chamber.
Known to the Applicant are United States patent applications having Publication Nos. 2007/0133742, 2008/0025470, 2013/0114788 and 2013/0336447. Also known to the Applicant is U.S. Pat. No. 7,706,507 and Japan Patent No. 3,946,612. Each of the mentioned patents and patent applications disclose systems for containing radiation within the scanning chamber while allowing the passage of an object when it is conveyed in or out of the chamber.
Moreover, a known process for the detection of explosive material involves manually taking a sample of fine particles from an object in order to subject the sample to a detection process. Typically such fine particles are collected with a cloth, which is then analyzed by an analyzing system which may include, for example, a heating chamber where the temperature is raised to gasify the particles containing explosive chemicals, from which the resulting gases are then analyzed with a spectrometer in order to detect the presence of such explosive chemicals.
However, the teachings of the aforementioned suffer from drawbacks. For example, the inspection of an object involves the separate processes of scanning the object and detecting explosives, which can be both complicated and time consuming. Preferably, these processes should be simplified in order to make the inspection of objects more efficient.
Hence, in light of the aforementioned, there is a need for an improved system which, by virtue of its design and components, would be able to overcome or at least minimize some of the drawbacks of the prior art.
