The Shielded Decay Drum provides the necessary shielding from high-energy radiopharmaceuticals. It has a handled lid with a 6.5" x 8" (16.5 x 20.3 cm) drop port. The drum includes three 30-gallon plastic liners. With two Shielded Decay Drums on hand, a rotation system can be instituted for an even more practical storage and decay process. The optional dolly simplifies transport of the decay drum.
