(This message was added in version 6.7.0.) in /home1/glenniehomeinspe/public_html/wp-includes/functions.php on line 6114This is the second of a three-part series of my investigation EMF in my house. There are many sources of information about\u00a0electromagnetic\u00a0fields (EMF) and the potential implications of them. It can be confusing and seem contradictory even. Here are two\u00a0opinions. \u00a0The first<\/a>\u00a0indicating that there does not seem to be much cause for alarm. The second<\/a> opinion is of a more alarmist tone. This is what Health Canada<\/a> has to say about the matter.\u00a0Whether being very concerned about this issue or merely taking a cautious precautionary approach, a home or building owner needs to have an EMF survey done to determine the magnetic levels. It is odourless, soundless, and colourless.<\/p>\n Essentially the survey involves taking a series of magnetic field measurements around the property with a magnetometer<\/a>\u00a0or as it is often called — a gauss meter<\/a>. Figure 1 shows the gauss meter that I use. It takes readings with the unit of measurement being the milligauss<\/a>\u00a0(mG). You will at times see magnetic readings in microteslas<\/a>\u00a0(\u00b5T) which is the\u00a0metric equivalent\u00a0of\u00a0the milligauss. The conversion is\u00a01\u00a0\u00b5T (microtesla) = 10\u00a0mG (milligauss).<\/p>\n Side note, I’m one of those people that does some of my technical thinking within the imperial measurement system\u00a0and some in the metric (SI) system. I find that many, but not all, of the metric units are easier to work with. In this case gauss seems simpler to deal with. Also the meter I bought is measured in milligauss. But I digress.<\/p>\n Anyway, the basic electromagnetic survey involves taking exterior magnetic measurements at say the four corners of the\u00a0building\u00a0and possibly some in between points. This gives a background reading that forms the baseline for further interior readings. Interior readings can be done on a grid basis or possibly just at key points of the structure. Depends on the level of\u00a0granularity<\/a>\u00a0that you desire.<\/p>\n I opted to take readings at a widely spaced grid and at key\u00a0locations such as the electrical service entrance and panel. When doing a survey it is important to note that there will be magnetic fields near anything that is\u00a0electrically\u00a0powered. The survey readings need to take this fact into\u00a0account. So valid readings are generally taken at least four feet from lights,\u00a0appliances,\u00a0electrical\u00a0panels and the like. Figure 1\u00a0shows typical household EMF levels near appliances. Away from any appliances, the magnetic levels should not be more than 1 or 2 mG.<\/p>\n
