Does Todd's mystery box contain dangerous radioactive material?

Yesterday I wrote an entry about the mysterious piece of equipment Todd Lappin bought from a Navy surplus sale. What is know for sure is that it is a "US Navy CP-748 Radiac," but there seems to be a lot of debate about what it actually does. Here's one alarming comment on Todd's Flickr page

RADIACs contain a radioactive source which can contaminate you and give you cancer. The source is shielded but I would advise you not to tinker with the internals of this device.



I'm a veteran who served on a US Navy nuclear submarine, BTW.

Is San Francisco about to be declared one big superfund site?
