Vehicle cabin inspection system and method

An inspection system comprising:

• a source configured to generate inspection radiation having a radiation dose;
• a collimator configured to collimate the inspection radiation into an inspection beam configured to irradiate a section of a vehicle in a zone of inspection;
• a filter located between the source and the collimator, the filter enclosed separately from the collimator, the filter having at least an attenuation configuration where the filter is configured to attenuate the radiation dose to a cabin inspection dose enabling inspection by irradiation of a cabin of the vehicle by the inspection beam, the cabin being configured to be occupied by a user;
• and
• an activator configured to modify the configuration of the filter, from the attenuation configuration to a cargo configuration, when a container of the vehicle enters the zone of inspection, wherein the container is configured to contain cargo and wherein, in the cargo configuration, the filter is configured to interact with the inspection radiation to provide a cargo inspection dose greater than the cabin inspection dose for inspection by irradiation of the container by the inspection beam.

A method for inspecting a vehicle located in a zone of inspection by using inspection radiation, comprising:

• generating inspection radiation having a radiation dose;
• and
• collimating the inspection radiation into an inspection beam configured to irradiate a section of the vehicle, the collimating performed by a collimator;
• wherein the method further comprises:
• filtering the inspection radiation between at least two configurations, between the generating and the collimating, the filtering achieved by a filter, the filter enclosed separately from the collimator, the filtering performed such that:
• in a cargo configuration, the filtering provides a cargo inspection dose for inspection by irradiation of a container of the vehicle by the inspection beam, the container being configured to contain cargo, and
• in an attenuation configuration, the filtering attenuates the radiation dose to a cabin inspection dose reduced compared to the cargo inspection dose yet enabling inspection by irradiation of a cabin of the vehicle by the inspection beam, the cabin being configured to be occupied by a user;
• and
• controlling the configuration of the filtering, such that the filtering is:
• in the cargo configuration when the inspection beam irradiates the container, and
• in the attenuation configuration when the inspection beam irradiates the cabin.
