If non-ionizing low temperature radiation can be harmful to humans, does that mean we can get health issues just from standing near another human body which emits EM radiation at a far higher frequency and energy density?
- manmal 9y agoA human body emits more radiation in the gigahertz range than a cellphone?
- ko27 9y agoI am talking about the infrared range, which is above 300GHz.
- cma 9y agoThe body also reflects terahertz radiation from the surrounding environment, even directly into other people's eyes. This has the bizarre side-effect of causing people to be able to "see" each other.
- slackingoff2017 9y agoThis is great
- katastic 9y agoWon't someone think of the children!?!?
- manmal 9y agoInteresting thought. Near infrared light does interact with cells (photobiomodulation), usually in a beneficial way. Maybe the wave form is another factor, or some frequency ranges are beneficial while others are not?
- hutzlibu 9y ago"some frequency ranges are beneficial while others are not" Certainly. Heat is nice (if not too much), but x-ray is usually bad. Gamma-rays a lot worse. And cellphone radiation is probably somewhere in between ... so like the article cites: we don't know yet. So I do not like sleeping next to my mobile nor have it next to lower body parts for too long ...
- thaumasiotes 9y agoHeat is not a frequency or a frequency range.
- BenjiWiebe 9y agoGenerally speaking, warm/hot objects radiate in the infrared range. In my understanding, all objects radiate something, unless at absolute zero.

- pmontra 9y agoIt's quite complicated. Interesting read: https://en.wikipedia.org/wiki/Heat https://en.wikipedia.org/wiki/Heat
- CyberDildonics 9y agoI don't think the radiation heat transfer from microscopic bodies is the same as saying a human body emits infrared light on a macro scale.
- boooooo 9y agoIt does though, that's how infrared cameras work for one thing.
- jjoonathan 9y agoIsn't there a pretty well-established (but small) link between temperature and cancer? There's probably a reason why all the RF cancer studies go to the effort of specifically controlling it and specifying that the effects they are interested in are athermal.
- robbiep 9y agoNo there is not. There is a well understood risk of cancer in people who drink really really hot coffee and tea in oesophageal cancer but in no other cancer is there a relationship
- dnautics 9y agoNot necessarily. One possible mechanism for non ionizing radiation to be harmful is for the RF fields to induce currents in the dna base stack (which is a conductor), jamming the base excision repair system, which is hypothesized to scan for muations by detecting when current is or isn't running through the dna. In this case, the RF wouldn't be mutagenic, but it would increase the likelihood of cancer. http://www.sciencedirect.com/science/article/pii/S0167488915000336 http://www.sciencedirect.com/science/article/pii/S0167488915...
