Posted By Alan McKerns 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 John Webster 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.

Posted By anon1234 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.

Posted By seamus 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 Brett Day 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.
