Does anyone have any detail or can point me in the direction of an ACOP's for the siting of the above? I've been asked by a friend to forward any detail on the appropriate distance that these have to be from a dedicated place of work . . . if any!
Cheers.

Posted By Oil Man Alan You could try the Dept of Health Website at www.doh.gov.ukThey have lots of info on mobile phones and masts. Hope this helps

I know this subject keeps coming up, but someone once told me that the power transmitted from the mast is no greater than that transmitted by a mobile phone and may often be less due to the more favourable position and size of the mast. So can anyone confirm this to be so, it seems reasonable enough, for if it is true then it provides a very simple explanation as to why we should not worry unduly about the safety of these masts.

The power of these masts/base stations varies. More importantly, the energy exposure is inversely proportionate to the square of the distance.The energy footprint is also highly directional. Thus, much of the research conducted (as reported via Ofcom /DoH - NRPB now amalgamated into DoH)regarding public exposure is not necessarily relevant to maintenance workers and the like.
I think this is still very much an unqualified and unrecognised risk. There were reports some time ago of base stations being hidden within canopies at retail filling stations. Consider the individual who has to go up there to (e.g.) change a light bulb, or re-livery the fascias, etc.
Most likely a mast sited on the wall or roof of your workplace will have no effect on the general public or building occupants. It may, however pose a significant risk to construction and maintenance workers.Ask the provider for a Risk Assessment?

Have a look at the mobile operators association website - put MOA into goggle and it should come up with it.
This should give some useful information, but ultimately it will depend on the the type and power, etc of the particular antennaes.

Thanks to all for the feedback it's been v.useful.
Seems to be that the best solution is to be armed with what info you can pick up from various websites/docs etc. and ask for clarification from the owner of the mast about the health implications to persons in the near vicinity and challenge if necessary.
I'm new to this forum and its uses and must say that it is very helpful at the job i assume it is aimed at: to give pointers and tips to aid us in our search for detail on aspects of the profession that we seek advice on.

Hi Alan,
The phone masts that you are concerned about, are they actually masts or are they mobile phone antenna located up on roofs?. If they are the base stations that are up on the roof you need to be careful about access to the roof, ie a locked door. Warning signs on the door to roof access.( warning on the radiation etc) A meter could be provided for anyone who goes up on the roof to ensure they do not go too close to the antenna. I think off hand the safe distance from the antenna is 2 meters. The mobile phone company should have their antenna chained off, with warning signs etc, but we all know what should be done is not always done. Think of a painter with a pace maker painting the roof area.
Up on some roofs the radiation can cause the picture in a digital camera to be distorted. Very often there will be more than one mobile phone operator operating from the roof/mast.
The radiation involved is non-ionisation radiation but can affect pace makers, and maybe people with problems with their CNS. There is the possibility of being up on the roof and not knowing that antenna are located there, as they are often hidden behind plastic panels. Put into what looks like a chimney etc.
ICNIRP in short for the international commission for non-ionisation radiation protection , look that up in the web and you will get lots of info.
Also perhaps the WHO might be a help.
For your info some antenna look like trees, so to blend in !
The information I got about the masts are that they are suppose to be safe , to the general public because the way that the radio waves are sent out,
There are special meters which are used to measure the various frequencies exposures. Any report I read in Ireland seems to report exposure levels way below the max exposure levels. COMREG have a site that might be worth looking at.
Hope this is of help.
Seamus

Posted By Chris Knagg I C N I R P International Commission on Non-Ionizing Radiation Protection What is ICNIRP? ICNIRP is the International Commission on Non-Ionizing Radiation Protection. It is a body of independent scientific experts consisting of a main Commission of 14 members, 4 Scientific Standing Committees covering Epidemiology, Biology, Dosimetry and Optical Radiation and a number of consulting experts. This expertise is brought to bear on addressing the important issues of possible adverse effects on human health of exposure to non-ionising radiation. ICNIRP's principal aim is to disseminate information and advice on the potential health hazards of exposure to non-ionizing radiation to everyone with an interest in the subject. ICNIRP's information and advice covers all of the non-ionizing radiations including, the optical radiations (ultraviolet, visible and infrared - and lasers), static and time-varying electric and magnetic fields and radiofrequency (including microwave) radiation, and ultrasound. Much of the information that ICNIRP provides is published in the form of scientific reviews and reports and the proceedings of scientific meetings. The results of these reviews combined with risk assessments carried out in collaboration with the World Health Organization, WHO, result in the publication by ICNIRP of Exposure Guidelines. Examples of these are guidelines limiting exposure to electromagnetic fields, to laser radiation, to ultraviolet radiation, to incoherent optical radiation and to ultrasound. http://www.icnirp.de/

Another option is to contact the technical/safety departments of the mobile phone companies themselves, I did some work for Orange and they have comprehensive procedures and guidance for working next to thier equipment.
