I'm not an expert, this is just paraphrasing and regurgitation of what I've read on ATS threads in the past.
The plastic liner will leech toxins into the food over time, and it also limits the storage time of the foods, but even with the liner they are still
probably good for 20 years or more. Old style canning with glass jars, paraffin, and tin lids is better for extreme long term storage.
But, as to the electromagnetics, they will not effect the can whatsoever. Any type of current will just be conducted to a ground source or
completelly ignored. Radioactivity is a little different. The tin, and the heavy metals in the food itself may absorb radioactive particles. There
really isn't much you can do about this unless you have a nuclear bunker with dozens of feet of earth above it, or a few feet of lead.
