Check the regulatory compliance of labels and markings on the packagings.

Check on the respect of regulatory criteria of dose rates and of external surface contamination (packaging and means of transport).

Measure of the dose rate at 1 m for determination of the transport index.

Loading of packages:

Wedging and tie-down of the packages, strap attachment points on the packaging body must satisfy the following criteria:

The positioning of straps on the lifting boxes can be carried out over the full length of the box.

A tie-down arrangement with 2 straps on the lifting boxes and 2 straps in proximity to the 2 central reinforcing hoops of the container is also acceptable.

A tie-down arrangement with 2 straps placed on the upper half-shell reinforcement, in proximity to the "inner" reinforcing angle bar of the lifting box is also acceptable.

Any strapping position less than 100 mm from the reinforcement is considered to be in proximity to the reinforcing hoop.

The placement of straps between 2 reinforcing hoops is expressly prohibited.

The safe working load of the straps is 5 tonnes maximum.

Check that the mode of transport is compatible with the transport index, the criticality safety index and the activity of the contents (e.g.: 100 A2 for river transport).

4. Empty packaging The empty packaging is transported as an "excepted package" subject to the following requirements:

The packaging is closed and supported in accordance with the requirements in Chapter 1.8 of this Report.

The internal and external contamination levels meet the following criteria:

4 Bq/cm2 for beta and gamma radiation emitters and low-toxicity alpha emitters; and 0.4 Bq/cm2 for all other alpha emitters.

These limits are average limits applicable over any area of 300 cm² of any part of the surface.
