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.

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