Certification

Licensed by Croft Associates Limited as a general purpose type A package, which is generally used for the carriage of medical radionuclides and samples in solid or liquid form. Approval Certificate Number GB/3975A/A-05.

Description

Package design number 3975A is designed on traditional engineering principles and manufactured from stainless steel to give a long service life. The package consists of an outer container drum, design number 3975, which carries a resealable inner containment can, design number 3976, within shock-absorbing packing.

The outer container drum, design number 3975, has a fabricated stainless steel body and pressed steel lid with a painted steel closing band.

The containment can, design number 3976, is a resealable stainless steel containment can that carries the radioactive contents in suitable primary containers. When contents are liquids (within syringes etc) absorbent material is to be provided that 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.

Containment

The containment system consists of the containment can, design number 3975. 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 (such as vials). Absorbent material must be used with primary containers that are not sealed (such as syringes).

Liquid contents are limited to a maximum volume of 1,000cm3 (1l) when packed in suitable sealed primary containers and 160cm3 when packed in non-sealed primary containers.

Maximum contents weight of can design number 3976, 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, as loaded and presented for transport, are within regulatory limits.
