Sea-Lands have been a popular way to transfer radioactive active materials between locations. The normal ways allows surveys to be done for contamination levels inside and out. At the same time radiation levels can be obtained on materials inside prior to installation, allowing accounting of shipments.These instruments are normal radiological tools as RO-2’s; GM instruments Ludlum E-140’s; Model 3’s or Ludlum Model 17’s.

Once locked up and surveyed outside the sea-land tagged, it’s off to the location on a truck or alternate means of travel. In some travel sea-land containers inside can move if not packed tightly. Rugged sea-lands can be moved in all directions even when it comes to over the seas. Lending the possibility of the cargo to be moved or broken loose. The possibility that incorrect results for surveys can always be a concern with shipping over the waters. Numbers of sea-lands reach their destinations that have to pass a survey check for entry into other countries. Major ports can handle the concerns by doing surveys but not all. When times get busy at ports any indications that indicate the possibility of a radioactive event may occur the container is put to the side, calls made to shipper for answers. The norm is to either pay for a contractor at the port to do a survey or the container is shipped back to the original port for resolution.
