EMF Radiation can basically be divided into EMF from wireless emitters ("smartmeters," microwaves, cellphones cell towers, wifi, etc) and magnetic radiation due to inadequately shielded or wired electric devices, appliances, and electric wires.
I recommend checking for WIFI Radiation levels inside homes, work, and public places, and determine if there are any radiation hotspots in highly used areas.
I downloaded a free Smartphone App "Wifi EMF Radiation" to check my home and found that next to my Wifi, the couch was a Wifi radiation hotspot, and often had high radiation readings of over 150% (above "Seletun Statement" Recommended EMF), even after applying aluminum mesh. I also use ElectroSmart, which also captures Bluetooth, and Cellphone readings.
I replaced my Wifi with a low radiation version - The JRS ECO Wifi Router. The default transmit power was 30mW, and I lowered it to 1mW. The WIFI Radiation measured at the couch dropped to average of 3-6%, with a max of 15% without any shielding.
The JRS ECO Wifi Router emits 90% less radiation by pulsing 10x/sec vice 100x/sec, and uses software to adjust the transmit power, features often not avail in standard routers. I read about this via https://www.electricsense.com/11779/eco-wifi-low-radiation-router/
While I was visiting a relative's NYC highrise apartment, I was curious and used the same cellphone WIFI Radiation Meter to check radiation, and found readings over 1000%. I was shocked and turned off their WIFI as they did not even use WIFI that Verizon had "given" them. WIFI Readings dropped to less than 10% in most areas, but my relative's bed was a +150% WIFI Radiation Hotspot - I traced to 23 of their neighbors WIFI Routers. Unfortunately, the damage was already done, his mild parkinson's and dementia, had already become late stage parkinson's after sleeping in a Wifi Radiation hotspot for over two years. Another bed two rooms away had close to 0 radiation; and the occupant was in good health compared to the member in the high radiation hotspot.
While waiting for the DC Red Line train, I also checked Metro Union Station, and they had 1400% WIFI Radiation. 5 2GB routers emiting +200%, and 2 5GB routers emiting +200%. I emailed the WMATA Metro Customer Service with my findings, but they have not responded to me. While waiting for an oil change, I checked WIFI levels at my car dealership customer service waiting area, and they had 1000% WIFI radiation. I emailed Customer Service with my findings, but they too have not responded to my findings.
What to do?
- Turn off WIFI when not in use
- Replace WIFI with a low radiation WIFI. such as JRS-ECO Wifi Router https://www.youtube.com/watch?v=1C3m_mcwHeI
- Apply shielding such as metallic fabric, metal mesh, microwave absorbing shields (advantage is less reflective)
- Wear EMF proof clothing in high EMF areas: I've measured high readings on trains, buses, and busy streets of NY. No need to just involuntarily absorb second hand radiation.
I also let WMATA know their trains exhibited high magnetic radiation in most areas. This makes sense as I would get extreme fatigue riding the Metro, especially on most spots of their trains. They were courteous, but did not advise if they would correct this discrepancy. I checked NYC subway trains and those were much lower than DC Metro trains. WMATA should learn how to fix their trains from NYC MTA counterparts. Amtrak Northeastern trains I measured high radiation coming from the floors of the trains. It could be due to net current, such as connecting neutrals to the chassis. Backs of most pubic buses are also very high.
Hybrid, electric cars, and vans with motorized sliding doors are very high and need magnetic shielding underneath carpets and glove compartments, whereas most ordinary cars need shielding for the driver and front passenger side.
Whenever the AC in my house turned on, there were hotspots in the dining room area where my EMF Meter read +5 mG (milliGauss). Anything over 2.5 mG is known to be unsafe. Using an EMF Meter ($35), I was able to locate and trace this to many wires between the smartmeter, and AC unit that ran underneath the floor of dining room.
The proper fix is to get an electrician to add proper shielding, replace wires, or rewire, but that will take much more planning, time and money.

MicroTesla Meter - Very sensitive meter for magnetic radiation and electric fields. Was able to detect the dirty electricity pulses from the Smartmeter every few seconds
ENV RD-10 - Three in one. RF, magnetic radiation and electric fields.
Chances are unless you happen to have a low EMF version, cordless phones do much more harm than good. I glanced over article "Cordless Phones: Even More Dangerous Than Cell Phones?" and did not take action - https://www.electricsense.com/815/cordless-phones-even-more-dangerous-than-cell-phones/
After I ordered $99 RF Radiation Meter (ESI 21) I did a survey to find any weak spots in the shielding against my neighbor's smartmeter. As I passed the cordless phone, the reading beeped to the second highest red reading just 4 ft away. I unplugged the cordless phone, and the continuous moderate/high reading immediately dropped to green. I don't understand why, but cordless phone bases constantly emit high wireless radiation, even when not in use. That's probably one of the reasons why I would get very tired teleworking. I suggest replacing with corded phone, from Staples, or Amazon.
Let's be clear on the dangers of high level microwave radiation from Bluetooth.
WIFI and Bluetooth is the same frequency as microwave ovens about 2.5 GHz, which is used to cook food.
I used my RF meter and observed excessive (+5000 ?W/m2) transmit power from Bluetooth and WiFI of cellphones, laptops, so called "smart" TVs. Be aware some "smart" devices continue to radiate after being turned off, while others turn themselves back on after a set time.
Avoid using Bluetooth - Do everyone a favor and please do not expose yourself and your friends and family to radiation.
Do not sacrifice health for convenience. Above are hidden sources (ie, Trojan Horses) of powerful EMF radiation that are harmful to people. Fortunately, countermeasures are available for these if recognized in time: Wifi, Cordless phones, Bluetooth, cellphones.
RF radiation over 30 microwatts per meter2 (uW/m2) will cause harmful biological cell changes.
