I was requested to measure the RF Radiation in various parts of Maple Ridge (MR) by a person wanting to move here. So I decided to drive about and see what RFR levels were evident.
I used a GigaHertz HF59B with the omni antenna and recorded the radiation levels using a GigaHertz NFA1000. (Thanks Hans). The meter and antenna were sitting in the passenger seat.
The readings are in µW/m². The meter maxed out at 300 µW/m² so the max may be 400, 600, or even 1000 µW/m². I shall have to re-do the drive with meter set to read the higher RFR levels. 1 - Leaving my house walking to my car on Kanaka Way - lots of WiFi from neighbours. 2 - Drive North on 232St - low levels - residential. 3 - Corner of Dewdney Trunk Road (DT) and 230St - HiRFR - WiFi from the Tim Hortons on corner 4 - 2 blocks S on 230St parked - very low levels - Close to Haney Pioneer Village 5 - DT and 228St - v. high RFR (?) 6 - South on 224St passing Lee Building which has many cell transmitters on roof - really bad. 7 - Further south on 224St high RFR levels - still in sight of the Lee building. 8 - Residential areas in North MR - LOW levels - Lots of trees - no sight of cell towers. 9 - DT East from Laity to 224St - v.v.high from tall apartment building at 222St with cell trans. 9+ - Parking at Friends in Need Food Bank - low RFR levels Conclusions 1 - Very high levels of RFR near cell towers. I have made several prior surveys in apartments close by. Not a place I would ever live. 2 - Many places in residential with acceptable low levels of RFR.
The levels of radiation will vary depending on the load, and the amount of WiFi you find is somewhat irrelevant where only the levels detected will help you determine if they are safe or not according to the Building Biology standards. Trees and other barriers such as hills and mountains along with the distance (square law rule) also make a difference. Hope that helps!
