I'm not sure if you're attempting to link some excessive EMI exposure you may have received three years ago to your current health conditions, or if you suspect you have an ongoing exposure situation in your current office. If it's the latter, why not go ahead and do a site survey of where you spend your time. For 7 bucks on ebay you can buy a broadband log-periodic antenna and then go down to your test equipment pool and borrow a spectrum analyzer. Get one with mixers and an internal preamp that cover at least up to 6 GHz. (hopefully they aren't spraying 28GHz around your office) Set it up somewhere near where you work. SAs commonly power-up doing a full span. With the antenna connected to its input, set its RWB to 120KHz or so, then go into is amplitude menu and turn its preamp on and then set its reference level to the point where the noise floor is toward the bottom of the display or at least to the point where its attenuator is minimum and energy peaks are not saturating the display. Then go into the trace menu and set a Max Hold. -you can then go about your business. After an hour or so, you can turn on a marker and do a peak search with it. Hopefully you don't capture anything much greater than -50dBm. You can continue to integrate the display peaks all day and just move the marker around to track the current peak. If you do capture strong peaks, I'd set a marker on all of them and go ahead and do a screen dump to a file. You might find that you're predominantly capturing your own cell phone or Wi-Fi usage. That's still useful data, since you can then change your wireless behavior accordingly. Fortunately, wired ethernet isn't a crime.
There are also potentially harmful electric fields as well as magnetic fields, but these are not commonly found in the modern office environment. Excessive electric fields are usually found in the ceiling or floors of older homes and condos using 60's style radiant heat schemes. Also, in the last decade, harmful levels of magnetic ELF are now sprouting-up in cars that park their car batteries in the trunk and route the high current alternator wire thru the passenger compartment of the car. Many of the German cars are now designed that way and expose their victims to filthy levels of > 200mG or more. Conceptually, you can cancel the field by routing a heavy gauge isolated return wire with the source wire, but the industry mostly relies on the chassis to carry the return current.
Then, if you're a frequent flyer during daylight hours, at 35K ft, you're getting about 10X or so of the amount of ionizing radiation, say 0.1mR/Hr, as you receive on the ground. This is direct genetic damage.
But as bad as these radiation effects are, nothing quite compares to the US government mandated and corporatized healthcare industry. [Imagine if you were fined (taxed) for not proving that you were toting around the minimum bronze cell phone every month.] They're more than willing to expose you to 3T or more for your MRI. X-Rays and radiation 'therapy' kill off one's immune system & if you watch much on the 'ID' channel, you soon see the legal commercials identifying that yesterday's wonder d--gs are tomorrow's lawsuits. -If you choose to go down this dark path, you need to realize that this is a business and you are a customer. And over the last 30 years or so they have been going out of their way to make sure you're a recurring customer. You best go to them to set a broken bone, and that's it. The rest is a healthy organic diet and exercise. -I hope this is of some help.
