Waste measurement - TGS Advantages
• One instrument provides total Assay result combining TGS measurement of
U, Pu and other radio-nuclides with Pu isotopic ratio analysis using LANL
PC/FRAM code.
• Provides tomographic maps of absorbers and sources in heterogeneous
matrices.
• Determines the inventory of U, Pu, and other radio-nuclides in non
homogeneous samples including pyrochemical salt residues.
• Extends the range of the SGS technique to heterogeneous sample, such as
pyrochemical salt residues containing lumps of Plutonium.
• A single calibration constant can be employed for each radio-nuclide
determined due to the bias reduction inherent in the TGS technique.
• Measures samples with Am-241 content which cannot be measured by
neutron techniques.
• Accuracy and precision sufficient to meet safeguards, shipping and disposal
requirements.
• Suitable for measuring Pu oxide in cans.
• TGS technique indicates when a measurement is not successful, avoiding
large errors.

Waste measurement – TGS Features
• Gamma-ray based NDA technique for the assay of U, Pu and radionuclides in waste, based on licensed LANL TGS technology.
• Incorporates Tomographic Gamma Scanner (TGS), Segmented Gamma
Scanner (SGS) and Plutonium Isotopic Ratio Measurement capability in
one instrument.
• Automatic gamma-ray energy calibration using the Se-75 transmission
source.
• Transmission corrections are achieved using a Se-75 transmission
source to develop a 3-D spatial map of the attenuation coefficient of
the sample.
• Manual or automatic drum loading.
• Measurement time of typically less than one hour. Increased accuracy
and precision can be achieved by extending measurement time.
• Mobile operator control console which is compatible with both Drum
TGS and UGS for Cans,which can be local or remote from the
instrument.
• Accuracy is typically better than 10% for measurement of cans and 20%
for matrices with average density 2g/cm3. It is better than 10% for metal
scrap matrices.
