Package Type

Designed as a Type A Package to the IAEA Regulations for the Safe Transport of Radioactive Material.


Certified as a general-purpose Type A package for the carriage of radionuclides in solid or liquid form.


The SAFDRUM is designed as a reusable package and manufactured from stainless steel to give a long service life. The SAFDRUM consists of an Outer Container Drum (Design No 3970), which carries a re-sealable Inner Containment Can (Design No 3971) within shock absorbing packing.

The Outer Container Drum has a fabricated stainless steel body and pressed steel lid held in place with a painted steel closing band.

The Inner Containment Can is a resealable stainless steel containment can, which carries the radioactive contents in suitable primary containers. When contents are liquids, (within syringes, etc,) absorbent material, which is to be provided, must be fitted inside the can.  When the contents are bottles or vials, these may be packed in plastic bags/containers, or carried in lead pots when additional shielding is required.


The containment system consists of the Containment Can. When liquids are carried, they are to be immobilised within the containment system using absorber or primary containment. A wide range of primary packaging (including lead pots used with bottles or vials) can be used, provided the packaging conforms to the specification referenced in the approval certificate.
