The short answer is: YES.
Humans emit Thermal Radiation. We glow in the infrared portion of the electromagnetic spectrum. It is completely harmless.
What about humans ongoing radiation therapy? This radiation is contained within the body and does not pose a radiation threat for anyone other than the recipient. In fact, the best thing you can do for your loved one who must undergo chemo or radiation treatments is to hug them often.
When you hug someone, you can share with them your love and also your electrons to facilitate the healing process. Love is a more powerful force than most people realize...and, it's something that never runs out. It only builds up the more often this force is tapped.
Loving others is a great way to help heal yourself, too!
