Abstract: Methods for transmitting digitized x-ray radiographs are disclosed. Digitization may be carried out through use of a digital camera or through digital radiography. After digitization is complete, in certain embodiments of the present invention, the digitized x-ray radiograph is encrypted. In other embodiments, a virtual private network is established. In still other embodiments, either before or after generating a digitized x-ray image, written notice to a human subject concerning the identity of one or more authorized intended recipients may be provided. All embodiments include transmission of the digitized x-ray radiograph.

Abstract: A leak detector for monitoring, in an area being investigated, the presence of a liquid having a characteristic fluorescence spectrum. The leak detector includes a radiation source, with the radiation provided to the area being investigated. The detector also includes a collector for collecting radiation, in the fluorescence emission band of the liquid being monitored, emitted from the area being investigated. The presence of this liquid is sensed by detection of a threshold level of collected radiation. The size of a stain of the liquid relative to the size of the field of view of the collector is then determined.
