Thermo Scientific™ Lutetium Test Adapters

Descrizione

Get reliable performance verification of your radiation detection equipment without the inconsistencies of conventional check sources. From beta contamination probes through gamma scintillators to high resolution detectors, Thermo Scientific™ Lutetium Test Adapters provide reliable results without half life correction, transport or decay/disposal issues. These innovative test adapters use high-purity natural lutetium oxide to produce a totally constant and homogeneous surface emission rate with well-defined, reproducible results, regardless of variances in the lutetium-oxide ceramics.

Lutetium Test Adapters offer unique advantages. The rare earth element lutetium contains the isotope Lu-176 with 3.6 E10 years half-life and a natural abundance of 2.6% which yields a highly reproducible and uniform activity of the pure element lutetium of about 50 Bq/g.

• There is no need for error-prone half-life correction or for reoccurring purchase of the (decayed) check sources.
• All test adapters of the same type have virtually the same activity.
• Beta-type adapters provide nearly identical surface emission rates.
• The design of specially shaped enclosures and high-density Lu2O3 ceramics minimizes the required activity for small-size detectors.
• Under US DOT or IATA rules for dangerous goods shipments, these adapters are not considered as radioactive material due to their natural origin and low specific activity.

Lutetium Test Adapters are available in a variety of sizes for use with various radiation measurement instruments:
