Abstract
A scanning apparatus for measuring the attenuation of radiation passing from a radiation source along a radiation path to a radiation detector includes a source of radiation; at least one radiation detector capable of detecting radiation emitted by the source a data processor associated with the at least one radiation detector for calculating a property of material present in a linear radiation path between the source and the at least one detector; and a spacer arranged between the source and the at least one detector. The spacer defines a space which is capable of excluding water and having an average density which is less than 1 gcm. The provision of a spacer in the radiation path enables more radiation to be passed along the radiation path because water can be replaced with a material which is less attenuating to radiation.
