Automated phantom assay system

Automated phantom assay system

An automated phantom assay system developed for assaying phantoms spiked with minute quantities of radionuclides is described. The system includes a computer-controlled linear-translation table that positions the phantom at exact distances from a spectrometer. A multichannel analyzer (MCA) interface...

Zusammenfassung:An automated phantom assay system developed for assaying phantoms spiked with minute quantities of radionuclides is described. The system includes a computer-controlled linear-translation table that positions the phantom at exact distances from a spectrometer. A multichannel analyzer (MCA) interfaces with a computer to collect gamma spectral data. Signals transmitted between the controller and MCA synchronize data collection and phantom positioning. Measured data are then stored on disk for subsequent analysis. The automated system allows continuous unattended operation and ensures reproducible results.< >
