The Cost of Containment
By Elizabeth Bennett
A "standard" shipping container is 8 feet wide, 8.5 feet high and 20 feet long.
It can hold as much as 19 tons of soft and hard goods.
Only about 2% of the containers that move through a port get screened. In Oakland, gamma ray scanners are used to boost that to 10%.
