http://nelson.beckman.illinois.edu/courses/neuroethol/models/jamming_avoidance/JAR.html I personally have a large cyst under the location where I kept my cell phone for years. Doctor said its not worth the operation unless I get psychologically bothered by it, which I am not really at this point in time. I don't know if its from the sitting pressure, repeated impacts (I like to wear basketball shorts and the phone kinds knocks around in there especially if I move fast), the temperature of the phone (conducted, i.e. when it was playing music), or from electromagnetic heating or from some kind of other electromagnetic effect or from chance, but its a big enough cyst that I kind of have an aversion to carrying a phone on me, just incase. But, I typically like being real loose so I will adjust my clothing to remove any pressure points as soon as I get an opportunity to do so (I do not wear any tight clothing at all), and i stay on the well ventilated side, shorts in cold weather and such, so i find the cyst some what suspicious. It's not a tumor though, at one point in time I almost cut it open with a knife but I got adverse psychological reaction from the blood. I also shower frequently. |

So far I've seen absolutely nothing conclusively linking EMF to any kind of health problems. Given the massive explosion in the use of mobile phones, microwave ovens, radar and other RF emitting devices in the last few decades, the last 10 years in particular I would expect an equally massive increase in health problems but we have seen no such increase. Most of the increases in cancer can be explained by a combination of longer average lifespans and improved diagnosis whereas previously a person may have died of "natural causes" or lived with discomfort caused by an unknown illness now they may determine it was a specific form of cancer or other disease that affected them. |

No, a HackRF cannot measure harmful levels of EMF, whether chronic or acute. Harmful levels will more than overload the detector. Consider a thermometer instead. :) Tim |

We've had a huge debate here before on harmful levels of EMF (someone thread hunt) and the genaral consensus is that harmful levels RF would be high enough to likely fry low level meters. However, if you are worried about things like a severely leaking microwave oven (which can happan), you can get decent quality meters for that. (microwave leak meters) |

There are all sorts of ways to measure safe/unsafe levels of EMF that are cheaper. Levels a tiny fraction of unsafe would ruin the HackRF. The purpose of the HackRF is to emulate receiver/transmitters across a wide spectrum. I am wondering what you think is "safe/unsafe" with regard to strength and frequency. Folks could advise you better if you were more specific. If you don't know, give us an example of something that might be unsafe in your mind and about which you wish to investigate. Keep in mind the "inverse square law". You don't have to be very far from something that is unsafe, even lethal, to be safe. |
