I had a free afternoon, so I decided to test the shielding effectiveness of a conex shipping container. Below is a link to the video, sped up to 20x to keep it to around a minute.
The results are presented in the last 15 seconds. The bottom line is that shipping containers of this type offer modest levels of shielding. I plan to conduct a subsequent test showing how they can be improved to better protect from an EMP.
