Abstract:

Apparatus for automatically scanning processed radiochromatagram strips. The apparatus comprises a carrier wheel having a processed chromatagram mounted on the periphery thereof by a strip of plastic tape. The wheel carries the processed chromatagram past a radiation detector. Photoelectric means are provided to provide signals indicative of the position of the carrier wheel. The apparatus includes electrical circuitry responsive to the signals produced by the radiation detector to provide a numerical display of the total radioactivity detected along the entire strip and for providing a numerical display of the radioactivity detected along a selected portion of the strip. A strip chart recorder is provided in the apparatus to produce a graphical display of the spectral distribution of the radioactivity along the entire strip. The apparatus includes logic means for controlling the functions of the apparatus to provide a completely automated system.
