This is a follow-up question to this question...

...exceperted here...
My next step is to purchase one of the measurement devices you mention
here toward the end of the answer...
       "Since there are a variety of devices on the 
        market that can measure EMF..." 
To whatever extent you feel comfortable, please provide either a) some
search terms, b) URLs or c) recommendations.

Dear donphiltrodt,

Thanks for the follow-up question.

You requested that I provide search terms, URLs and/or recommendations
concerning the purchase of an EMF measurement device.

The following is a list of EMF measurement devices and services – the
source is well regarded, it is the Bridlewood site mirror currently
hosted by the Swedish site, FEB – the Swedish Association for the
ElectroSensitive –

Here’s the list -

There are also a number of good references appended to this list for
those planning to make their own measurements – they are at the very
bottom of the page.

If you are able – and want to – get highly technical about the subject
of EMF measurement, there’s an IEEE book out on the subject – here’s a
review –

It’s actually available from Amazon, but there’s only one in stock!

The following list details some of the major brands in radio frequency
and magnetic field measurement – suppliers are UK addresses, but
manufacturer contact info is also supplied –

Here’s one more list – it’s extremely comprehensive and covers a wide
variety of measurement services and devices, including radiation
measurement etc.

Once you have a device, you’ll want to know how EMF should best be
measured.  Dan Friedman offers “Suggestions for EMF measurement
procedures” at –

There’s also an EMF measurements database that will allow you to
compare and benchmark your results –

The following page from the Pacific Northwest National Laboratory
describes how electromagnetic fields surrounding a device should be
measured –

More info on measurement – original .pdf not available, but .html
available from Google cache –

Excellent tutorial on EMF measurement –

I hope this response adequately addresses your request.  I have not
been able to find recommendations.  Please let me know if you are in
need of additional information concerning this query – I am leaving in
a few minutes for the long weekend, but would be glad to conduct
additional research within the scope of this question if you would so
require – I’ll also gladly scour the Web for concrete recommendations
on Tuesday, so let me know if you would like me to do that (I need to
leave in a few minutes and have a 3.5 hour drive in front of me with
three kids...).

Wow.  That's a lot of info, but I'd like you to boil it down for me. 
Here's the bottom line...

I want to measure the amount of radiation in front of my monitors. 
Then if/when I purchase LCD monitors, I'll remeasure the radiation. 
What product should I to purchase to accomplish this, if any exists?

...Since I didn't specifically request an analysis (I should have),
please let me know if I need to raise the question price.

Dear donphiltrodt -

Good to hear from you again.
I will reply in this thread, and if you feel my effort was worthwhile,
you will be able to provide me with a tip when you rate my answer.

Please allow me a day or two to research the requisite materials and
come up with a recommendation.

Dear donphiltrodt, 

My apologies for not completing this yet, you should have a response
by tomorrow morning.

Dear donphiltrodt,

Your follow-up question was as follows - 

"I want to measure the amount of radiation in front of my monitors. 
Then if/when I purchase LCD monitors, I'll remeasure the radiation. 
What product should I to purchase to accomplish this, if any exists?"

The Health Physics Society (HPS) reports the following at -

"To make scientifically reproducible electromagnetic field
measurements requires a rather expensive meter to characterize both
the electric and magnetic components of the field. Manufacturers such
as Holaday Instruments make excellent research-grade equipment."

Note that Haladay had been bought out by ETS Lindgren - Web site is at

I called the company at -

Phone: +1.512.531.6400

The engineer I spoke with recommended the following model - 


The cost is $1555, and you can purchase it be calling Tiffany at -


As you will see when you hit the Web page, there's a picture of a
monitor in front of the probe.
Other contact information for this company:

Address 1301 Arrow Point Drive
Cedar Park, Texas
Fax: +1.512.531.6500
Time zone: Central Standard

More from the HPS site - 

"To conduct a quick demonstration of the presence or absence of 60 Hz
magnetic fields without concern for a high degree of accuracy, there
are a number of inexpensive meters on the market for $50.00 or even
less. Search the Internet for inexpensive EMF meters to find several
alternatives... One factor to watch for in selecting an inexpensive
meter is the range of frequencies to which it will respond. If you
want to measure only the 60 Hz component, then you should buy one that
rejects radiofrequency signals, and vice versa. There are also a
number of consulting companies that will provide professional
characterization of electromagnetic field environments."

Searching for inexpensive meters results in the following - 

Several models, ranging in price from $50 to $150 -

Here's another model for $159 -

And, again, many different meters for a variety of price points, some
from well-known name brands such as Sperry -

I can't say whether the inexpensive models will measure the variance
you will find as you migrate from one type of monitor to another - on
the other hand, you probably don't want to spend upwards of $1500 for
the measuring device...

Good luck with your experiment - and please do contact me in the
future if you need additional research on this or other topics.

Good work. Thank you.  Tip is for additional out-of-scope research.
