Several portable instruments are designed using previously reported CdTe detector technology. These can be divided into three groups according to their energy ranges: (1)3–30keV XRF analyzers, (2)5–120keV wide range XRF analyzers and (3)γ-ray spectrometers for operation up to 1500keV. These instruments are used to inspect several hundreds of samples in situ during a working day in applications such as a metal alloy verification at customs control. Heavy metals are identified through a 3–100mm thick package with these instruments. Surface contamination by heavy metals (for example toxins such as Hg, Th and Pb in housing environmental control), the determination of Pb concentration in gasoline, geophysical control in mining, or nuclear material control are other applications. The weight of these XRF probes is about 1kg and two electronic designs are used: one with embedded computer and another based on a standard portable PC. The instruments have good precision and high productivity for measurements in situ. The detection limit of Ce is about 0.03% when measured in the presence of 10% barium for 15s. The detection limit when measuring K-shell X-ray of heavy metals contamination is about 0.1mg/cm2 for 15s. Two types of probes for γ-spectrometry with small and large (>30mm 3) detector volumes provide both high- and low-activity of nuclear fuel analysis. The maximum distance between the probes and electronics unit is 20m. The γ-spectrometers are equipped with electronics to correct signal distortion due to slow carrier effects. This allows the instrument to achieve an energy resolution of about 2.5keV at 662keV. Several modes to process spectra are possible including semiquantitative and total real-shape fitting.
