You have good reason to think this sounds absurd, because, well, this is absurd. The answer to your question is unequivocally, "no!"
The first warning signs:
- Grammatical/typographic/formatting errors in the warning itself.
- Asking to "Kindly pass this information to your contacts." - Eric Idle said it best, spam spam spam spam.
- The misnomer of calling what should be "irradiated" food "radiated" food. Radiated food would just be food emitted from someone or something, which would be a great idea for a super-power...
- If this was a legitimate study, it would be groundbreaking, and would be receiving enormous media attention. Just think about how many official studies and media buzzes one encounters (and how many questions have been asked on this site) regarding cell phone radiation and health. Wouldn't this be an even bigger bombshell?
To put a little actual backbone into it, though, check out this site; it does a nice job at quickly and simply debunking this.
To summarize the finer points of the above link:
- Check out Princeton's research page - you won't find it there!
The author claims to have contacted Princeton about this, and received the following reply from a spokesperson (granted, without seeing an email, this is just as specious as the claim itself):
To confirm, we are not aware of any such research affiliated with anyone at Princeton and unfortunately we do not know where or why this e-mail chain started.
We appreciate you informing your readers that this e-mail is a hoax.
Don't forget, how do you think refrigerator doors stick when closed? Magnets! Furthermore, many electric motors (like the one that makes refrigerators work) generate electric and magnetic fields on their own - certainly larger than the miniscule one produced by a refrigerator magnet.
The above site also links to the National Cancer Institute, a great source for this kind of information. Looking at this linked page, one can see (with regard to humans):
No consistent association between magnetic fields and leukemia or brain tumors has been established.
And to follow up on the whole mouse thing:
Animal studies have not found that magnetic field exposure is associated with increased risk of cancer (2). The absence of animal data supporting carcinogenicity makes it biologically less likely that magnetic field exposures in humans, at home or at work, are linked to increased cancer risk.
So no. There is nothing to worry about with refrigerator magnets. Unless you eat them. That might be a problem.
(I also think a fair name for this whole fiasco could be: decorative magnets, how do they work!?)
