I've been worried about EMF after I discovered this website: https://emfacademy.com/imac-radiation/
Even at 3 feet away, a 21 inch iMac just barely fits within the recommended range.
So it seems to me that you would have to be even a little more farther than 3 feet to use a 27 inch iMac (which I have) in the recommended range. But that would be too much of a distance and would defeat the purpose of a big screen. So I'm trying to buy an external monitor and a desktop.
These are the full test results given on above website:

2015 iMac 21.5″
1 Inch Away = 66 mG
1 Foot Away = 16 mG
3 Feet Away = 2.4 mG (.5 to 2.5 is recommended)

The website gives the following numbers for average monitors:
1 Inch Away = 25 to 500 mG
1 Foot Away = 0.4 to 20 mG
3 Feet Away = <0.1 to 1.5 mG

The ranges are too broad for the above results. It’s showing that some monitor is 0.4 at 1 ft away while some monitors are 20mg at the same distance.

I don’t want to take the risk of developing brain tumor later in life, so I’m looking to switch to a tower computer, whether a used Mac Pro, Mac Mini, or PC desktop together with a monitor.

I’m basically looking for a monitor where I can be only 12 inches to 14 inches away but don’t have to worry about EMF.
TriField T2 is the type of EMF Meter used by the author of the above website: https://www.amazon.com/dp/B078T2R64C/?tag=emfacademy-20

Could someone buy the TriField T2 Meter and see what the EMF numbers are like for any of or all of the following monitors that I’m considering?

LG Ultrafine 27 inch: https://www.amazon.com/LG-27MD5KL-B...ild=1&keywords=lg+5k+27&qid=1592355175&sr=8-2

LG Ultrafine 24 inch:

Samsung 32 inch: https://www.amazon.com/Samsung-Clas...samsung+curved+monitor&qid=1592356316&sr=8-16

Or whatever monitor you are using at the moment.
If you could post here what model of monitor you are using currently and what the mG is like at various distances (I’m mainly concerned distance of 12 to 14 inches away) I would appreciate it.

I can't find the EPA numbers they claim anywhere and they don't link their sources. In fact, the EPA page says there is nothing conclusive. The Australian EPA says that 1000 miligauss is the safe limit, which the iMac is very well within.

I think that website might be making stuff up unless the EPA numbers actually exist out there. What the EPA actually does say is that there is no known link between EMF and Cancer, and that research suggests there is no link.

A basic problem is that the iMac is going to have a lot less EMF than say... the power line in your wall. So it seems a little strange they're so concerned about the EMF of an iMac and not the EMF of the walls of the house you're using the iMac in. Electricity is EMF.

RF radiation is regulated, and yes, the iMac will put off RF radiation through it's Wifi. But the website fails to mention that the iMac's RF radiation is under the limits and is considered safe.

An old Mac Pro pulls a whole lot more power than an iMac, so it’s going to produce a lot more EMF. But again, I don’t see any EPA guidelines about safe EMF levels like they’re claiming.

I'll try to contact someone EPA about the numbers.

I was thinking I could place the Mac Pro far away from my body as there would be no need for it to be close and also I could even put aluminum cover (made of aluminum foil) on it.
 
The problem with putting foil on your monitor is that all your other appliances are still emitting EMF. It would be expensive and impractical to cover them all, and you might block vents on your appliances. Instead, you should cover yourself in the foil.
 
Given that there's nothing at that EMF website that indicates anyone involved has any sort of credentials related to the field, I would take anything reported there with a huge grain of salt. What I see on the site is a lot of links to selling things with no proven scientific value through affiliate links.

I wouldn't be putting foil on the monitor, because then I can't see the monitor.
I would be putting it on either the tower if going the desktop route, or the bottom half of the laptop (that is, the non-monitor part). I would make the foil in such a way as not to block the vents.

There's nothing you can do to reduce EMF on all-in-one computer because the computer is located and fixed right at the back of the monitor, and the EMF comes through the monitor, and blocking it would involve blocking the front of the display with foil, making it unusable.

I found another research that gives an even lower number within safety: 1 mG.

Bioinitiative Report of 2012 -- Recommendation of 1 mG limit
Seletun Scientific Panel of 2011: Recommendation of 1 mG exposure limit.

From: http://www.emfwise.com/powerline.php#:~:text=Safety Recommendations,the Seletun Scientific Panel recommendations.
