Other dangerous properties of contents

The non-fixed contamination on the external surfaces of any package shall be kept as low as practicable and, under routine conditions of transport, shall not exceed the following hmits  

These limits are appUcable when averaged over any area of 300 cm of any part of the surface. 

Except as provided in para. 514, the level of non-fixed contamination on the external and internal surfaces of overpacks, freight containers, tanks, intermediate bulk containers and conveyances shall not exceed the limits specified in para. 508. 

Packages which are damaged or leaking radioactive contents in excess of allowable hmits for normal conditions of transport may be removed to an acceptable interim location under supervision, but shall not be forwarded until repaired or reconditioned and decontaminated. 

A conveyance and equipment used regularly for the transport of radioactive material shaU be periodically checked to determine the level of contamination. The frequency of such checks shall be related to the likelihood of contamination and the extent to which radioactive material is transported.
