Abstract: The present invention, in some embodiments, relates to radiation-shielding containers for housing radioactive materials. For example, some container assemblies of the invention include a body and a lid both including radiopaque material, and together defining a receiving space for radioactive material. Each of the body and lid has a closure surface that is in close proximity with the closure surface of the other when the container assembly is in a closed condition. The closure surfaces of these container assemblies may be configured such that they run substantially entirely at an angle to a local direction of radiation emanating from the radioactive material. In other words, these closure surfaces may be oriented such that they are misaligned with radiation emanating from within the container assembly. The present invention, in some embodiments, relates to devices for administration of radioactive material (e.g., radiopharmaceutical capsule) to patients.
