Package Type

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


Previously certified as a general purpose Type A package, which is generally used for the carriage of medical radionuclides and samples, 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 3975), which carries a resealable Inner Containment Can (Design No 3976) within shock absorbing packing.

The Outer Container Drum has a fabricated stainless steel body and pressed steel lid 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 is to be provided which 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 Outer Containment Can. When liquids are carried they are immobilised within the containment system using absorber or primary containers. 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.

Approved Contents

  • Radioactive material in liquid or solid form. A variety of sealed primary containers can be used with liquid contents (e.g. vials). Absorbent material must be used with primary containers that are not sealed (e.g. syringes)
  • Liquid contents are limited to a maximum volume of 1000 cm3 (1 litre) when packed in suitable sealed primary containers and 160 cm3 when packed in non-sealed primary containers
  • Maximum contents weight of Containment Can including additional shielding is 17.5kg
  • The contents are also limited to A1 for material in special form and A2 for other material, with the additional requirement that the external radiation levels of the package, during routine and normal conditions of transport, as loaded and presented for transport, are within regulatory limits

Modes of Transport

By road, rail, sea, air and inland waterway.
