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.

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.
