51,464,450,000,000 Hz is right smack in the middle of the Infrared-C spectrum. Frequencies of EM radiation in the IR-C range have no undesired effects provided they are of the proper intensities for the said applications. Frequencies higher than IR-C have non-thermal effects -- such as aqueous flare and retinal damage -- caused in part by photochemical reactions. Frequencies lower than IR-C can fry internal organs.
As for cancer, no need to worry. Cancer is one of the results of the photochemical reactions caused by UV lights. My hypothetical device only emits IR-C light -- which is cancer-free. IR-C is absorbed by vibrational transitions and causes only a rise in temperature. UV light -- and frequencies higher than UV -- disrupt chemical bonds and definitely do increase the risk of cancer, if not outright causing the cancer. This is at least partially because UV is absorbed by electronic transitions.

So you're talking about a tanning bed that doesn't tan?
Yes. It's meant to warm the user as if he/she is basking on the beach on a summer day -- without the effects of EM radiation outside of the IR-C spectrum.
Would the IR result in vitamin D production?
No.
To combat seasonal affected disorder?
I doubt it. Seasonal Affective Disorder requires the use of visible light -- not IR -- as part of the treatment.
What PRICE do you have in mind?
I don't know.
Are you writing a comic book or science fiction?
Neither.
