摘要： A hybrid radiation detector is described comprising a first energy discriminating detector element selected to be sensitive to incident radiation of a lower energy range and a second detector element selected to be sensitive to incident radiation of a higher energy rage and a second detector element. In embodiments, a first detector element comprises a semiconductor detector; and a second detector element comprises a scintillator detector. The first detector element may thus be suitable to be more responsive to radiation in a first, lower energy range and/or configured and arranged to collect incident radiation emergent from a target of such energy that the photoelectric effect predominates as an attenuation mode in the target; and the second detector element may thus be suitable to be more responsive to radiation in a second, higher energy range and/or configured and arranged to collect incident radiation of a generally higher energy. A method of detecting radiation using such a hybrid detector is also described.

摘要： A conveyor system is described for use with a scanning apparatus (49) for the scanning of objects (43), such as bottles. The system comprises a transverse conveyor having a conveyor surface (45); a plurality of object support modules (41), each object support module (41) comprising a lower surface that sits upon the conveyor surface (45) of the conveyor and an upper part in which an object receiving recessed portion is defined, wherein the object receiving recessed portion defines an elongate recess having a constant transverse profile. A scanning system comprising the conveyor system in combination with an object scanner and a method of scanning embodying the principles of such a scanner are also described.

摘要： A method of radiological examination of an object for the identification and detection of the composition the object comprising the steps of: irradiating an object under test with high energy radiation such as x-rays or gamma-rays and collecting radiation emergent from the object at a suitable detector system in such manner that emergent radiation intensity data is collected for the entire volume of the object under test; numerically processing the radiation intensity data to obtain a first data item correlated to the total number of electrons within the sample; applying an alternative method to obtain a second data item correlated to another property of the sample; using the first and second data items to derive an indication of the material content of the sample.

摘要： A method is for the deconvolution of a statistically noisy spectral dataset is described comprising the steps of: a. obtaining a spectroscopically resolved dataset of measured flux from a sample that has been collected using a suitable detector radiation system; b. generating an initial estimate of the true spectrum; c. modifying the estimate of the true spectrum by a response function of the detector used to collect the measured flux dataset so as to generate an estimate flux dataset; d. computing a merit value for statistical fit between the measured flux dataset and the estimate flux dataset; e. applying a perturbation to a value of the estimate of the true spectrum; f. repeating steps c and d to the estimate of the true spectrum so changed, accepting the change to the estimate of the true spectrum if the resultant merit value indicates an improvement or if the resultant merit value indicates a deterioration of less than a limit margin, and rejecting the change to the estimate of the true spectrum if the resultant merit value indicates a deterioration of more than a limit margin; and g. repeating steps e and f for each further value of the estimate of the true spectrum to obtain a modified estimate of the true spectrum; h. repeating steps c to g for successive modified estimates of the true spectrum while reducing the limit margin. More completely, a method of detection of a spectrally resolved radiation dataset is described embodying the above.
