I need a single comprehensive table of all international limits in the
band 400- 2000 MHz, in order to compare standards of human hazards,
around Cellular Base Stations. The data should be in a tabular format:
a comparative table, for as many as possible countries around the
world, to compare the different values. The countries are defined by
their name and by ISO 3166 Code (used also by the World Bank).
ICNIRP levels are specified in ICNIRP ?Guidelines for Limiting
Exposure to Time-Varying electric, magnetic, and electromagnetic
fields (up to 300 GHz)?
://www.google.co.il/search?hl=en&q=%27Guidelines+for+Limiting+Exposure+to+time+varying%27&btnG=Google+Search
25 March 05; Table number 7 is: ?Reference levels for general public
exposure to time-varying electric and magnetic fields (unperturbed
rms values)?. At 400?2,000 MHz the values are 1.375 sqrt f (MHz) V/m
or f/200 W/m2 .
My requested values of national standards in the UHF band should be
specified as a rate relative to ICNIRP; or the Field Strength or Power
Density in units Volt/ meter (field strength) or W/m2 (power density).
?Not Available? when there is no data.
Example: GBR, United Kingdom, 0.125f (in GHz); source WHO web site.
The main data appears in the WHO website:
http://www.who.int/docstore/peh-emf/EMFStandards/who-0102/Worldmap5.htm.
Pls use additional wenb sites and pls specify the source of the
information on every country. |

Dear Researchers- more than 2 weeks and no response?! The Q is not so
difficult. All the data is in one web site. I assume that most of the
(developing and Least Developed)contries even did not respond to the
WHO web site:
http://www.who.int/docstore/peh-emf/EMFStandards/who-0102/Worldmap5.htm
I need only one response of the country, the question in the web site
'Are the limits based on ICNIRP? #9'
There might be other studies that already retrieved this data. Success. 5013-ga

I'm confused because the data you're asking for in the original
question are much more extensive than what you specify in the
clarification. Please help me understand what you're looking for.
Would you be content with a spreadsheet composed solely of information
that can be gleaned from the site entitled "EMF World Wide Standards"?
As you point out, most of the developing countries have no EMF
information available, or at least nothing published in their entries
on that site. I'm also unsure whether you want a quantified measure of
the national standards in the UHF band, as you specified originally,
or merely the answer to question #9 in each entry, as you state in the
clarification. Please advise.

Yes my colleague leapinglizard-ga is correct. We hope you can make the
requirements clear for your question. Maybe you can make a sample
table so that we can get a good picture of what you really want.
Example:

OK easterangel-ga leapinglizard-ga you are right. The Q. needes
clarification. I need an Excel file to specify the limits for the
General public(Uncontrolled) -not the Occupational values; in the band
about 300-1500 MHz; f in MHz ; units of 'field strength' 'E field'in
Votl/meter, and power density 1 W/m2 (that equals 0.1 mW/cm2).
The Columns are: WorldBank Code; Country Name; Field Strength (V/m);
power density (W/m2); the specific site specified inside the web
http://www.who.int/docstore/peh-emf/EMFStandards/who-0102/Worldmap5.htm;
Remark.
Examples:
1) FRA;France; 1,375 SQRTf;
f/200 http://europa.eu.int/eur-lex/pri/en/oj/dat/1999/l_199/l_19919990730en00590070.pdf;
FRA follows EC 1999/519.
2) CHN; China; 12; 04;
http://www.who.int/docstore/peh-emf/EMFStandards/who-0102/Asia/China_files/table_ch.htm.
3)JPN; Japan; 0.001585SQRT f; f/150;
http://www.who.int/docstore/peh-emf/EMFStandards/who-0102/Asia/Japan_files/table_ja.htm.
4)PHL; Philippines; n/a; n/a;
http://www.who.int/docstore/peh-emf/EMFStandards/who-0102/Asia/Philippines_files/table_rp.htm;

5)USA;USA; n/a; f/150;
http://www.who.int/docstore/peh-emf/EMFStandards/who-0102/North_America/USA_files/table_us.htm
Hope that now it is clearer. In the end, any clustering comment such
'as most EU countries follow EC 1999/519' are important. SUCCESS!

Hi again 5013-ga!
Since this is a very tedious project, is it ok if we could limit the
task of compiling data from the WHO website only? Meaning our research
will be limited by the numbers at WHO.

Thanks!

Dear 5013,
The WHO website lists 155 independent countries altogether, but 111
country listings read simply "Unknown". Of the remaining 44 countries,
22, or exactly half, are known to follow the ICNIRP standard. Here is
a spreadsheet naming these 44 countries in the format you specified.

leapinglizard GOOD! My clarification on 12 Apr 2005 included a Remark
column; the last one. e.g see for France: 'follows EC 1999/519'.
I consider that countries like Denmark, Austria, Finland, Norway...
defined limits, or they adopt clearly ICNIRP f/200, or at least they
follow the European Council Recommendation EC 1999/519. leapinglizard
pls add this information (or other significant) as an additional
column. Any clustering or common pattern to the 44 countries or part
of them? Any common to all 155-44 others specifying 'unknown'? Russian
0.10(0.25h?) power density is not clear.

I'm sorry I've left you hanging so long. I was away much of last week,
but now I'm back and I'm attending to a backlog of questions. I will
get around to addressing your Clarification Request quite soon. You
needn't worry if the question is marked as Closed. We can still
correspond through the Clarification mechanism. Please rest assured
that your satisfaction is my priority.

I shall address your concerns in the order in which you expressed them,
quoting from the Clarification Request in each instance.
My clarification on 12 Apr 2005 included a Remark column;
the last one. e.g see for France: 'follows EC 1999/519'.
I consider that countries like Denmark, Austria, Finland,
Norway... defined limits, or they adopt clearly ICNIRP f/200,
or at least they follow the European Council Recommendation
EC 1999/519. leapinglizard pls add this information (or other
significant) as an additional column.
I have revisited the countries for which the entries in columns C,
D, E showed "n/a", "n/a", "no". In some cases, I found additional
information that allowed me to correct the entry or to supplement it
with a remark. The updated spreadsheet is at the following address.
http://plg.uwaterloo.ca/~mlaszlo/answers/limits_info.1.xls
In the case of Finland, the WHO web page clearly states "No" in response
to the question, "Are the limits based on ICNIRP?" For Norway, it says,
"Daily work based on the ICNIRP standard," but this obviously refers
to occupational bandwidth limits rather than those applicable to the
general public. There is no information on the latter.
I am informed by several web sources, including the following PDF
document, that the ICNIRP limits and those found in EC 1999/519 are
identical. Thus, column E of the spreadsheet already answers your question
about EC 1999/519.
"European Council Recommendation 1999/519/EC concerns the limitation of
the exposure of the general public to electromagnetic fields. The basic
restrictions and reference levels contained within the Recommendation
are identical to those published by ICNIRP with regards to the general
public (as per Tables 3 and 4 above)."

Any clustering or common pattern to the 44 countries or part of them?
I did keep an eye out for interesting patterns, but, much to my surprise,
I found none. For example, I had expected to find that Western European
and Eastern European countries would be distinguished from each other
by some trait, but I found no evidence for this in the data. Countries
on either side of the East-West divide are neither more nor less likely
to comply with the ICNIRP limits.
Any common to all 155-44 others specifying 'unknown'?
These countries tend to lie outside Europe. In other words, bandwidth
hazards in Asia, Africa, and South America are not as closely or clearly
regulated as in European countries. I had somehow expected this.
Russian 0.10(0.25h?) power density is not clear.
I don't understand it either, but that's what it says on the WHO web
site. The table near the bottom of the page shows "h." as the exponent of
"0.25", the whole being enclosed in parentheses and preceded by "0.10". No
doubt the Russian are using some idiosyncratic measure of their own.
