********************************** Q - What is the best way to use a cellphone?A - Regarding a cellphone, this is the list from best to worst (not for EHS persons):
Numbers 9 and 10 are the worst, it is hard to say which one is better. For more info on this issues please see: http://www.norad4u.com/emr-reduction/using-the-mobile-phone ********************************** Q - Which cellphone is best to use in the car?A - a fixed car cellphone with an external antenna. ********************************** Q - Do cellphones emit EMR when in standby mode?A - Yes, in the following cases:
********************************** Q - How can I limit my EMR exposure?A - Your exposure depends on the levels and time of exposure. In order to limit your exposure you need to reduce both. Reducing the levels can be done by putting more distance between you and the source (a cellphone for example) and by using a device that emit less EMR. In addition it is very impotent to limit the use and to minimize your time on the cell phone and around other EMR sources. ********************************** Q - Is it safe to use Power line networks?A - Power line networks is a technology in which the PC network is embedded onto the electric power lines inside the house. I think Power line networks technology is much better than WIFI (as far as EMR is concerned) but it produce some Dirty Electricity (low-mid frequency single over the power line). The best thing to do (as far as EMR and speed is concerned) using CAT5 or CAT6 network cable is the best way to go. ********************************** Q - Do wired (usb, microphone) ear piece emit radiation, compared to a Bluetooth ear piece?A - In general wired equipment emit no Radio Frequency (RF) Electromagnetic Radiation (EMR). It may however emit some Low frequencies. When connecting to a cellphone some of the RF EMR may makes it way up the wire and to you ear/head. Compared to a Bluetooth earpiece, I would se wired earpiece any time. Bluetooth emits RF EMR all the time it is coupled with the cellphone (which does the some, emitting RF EMR when coupled with a Bluetooth earpiece. Please see the following clips: ********************************** Q- Why is it so complex to measure RF radiation from cellphones?A - Most RF meters actually measure electric field (in V/m2 units) and then calculate the RF levels (in mW/m2 or uW/cm2). This calculation is possible and correct only if done in the far field. Therefor if you use a RF meter to measure RF from a cellphone right next to it you will not get the right levels. What you can get is an indication that there is radiation (and this is what I try to show in my videos). In order to measure the RF from a cellphone you need to measure it in the far field and then to calculate the levels that are next to the phone. An other may to do it is to use electric field meters (I have 2 and in some of the videos I use them). But this is not the end of the story. Cellphone emit high RF radiation in high frequencies (most of the times more then one frequency) but also low frequency electric and magnetic fields. You need also to measure them and to take them into consideration. Measuring all the levels in all the frequencies emitted by a cellphone is very problematic and very complicated. Please see the following videos: Video clip:Different types of radiation from cellphones **********************************
Q - Radiation from DECT handset compared to the base stationI am curious about the field strength of the DECT handset compared to the base station do you know if this is exactly the same when making a call or does the base station radiate more? A - I think that both the handset and the base station emits RF levels which are too high and not healthy. The base station emits the RF all the time, the handset just when talking. Any other comparison between the two is not relevant. ********************************** Q - Does WIFI adjust their transmitting power according to the signal strengthDo you know if laptops with wifi do adjust their transmitting power according to the signal strength of the router? So, when close to a router, will the output power of the laptop be very low or will it be always the same, no matter what the distance is? A - As far as I know laptops always emit the highest possible signal. In case of many errors more info will be transmitted again and again which will cause for more exposure in the time and frequency scale. I recommend using wired PC network, if you must use a wireless network (router and PCs) try to keep as much distance between you , the router and the wireless network card. Please see more details in my site at: and ********************************** Q - How to get low radiation cordless phone in US/CANADA?A - First of all please note that there is no such thing as a safe cordless phone, every cordless phone emit Radio Frequency (RF) radiation when using it. DECT phones are the worse as their base station emit RF all the time. In the US and Canada there are no real ECO DECT phones on the market(2013). You can always order from EU or other countries and risk that some of the options will not work in the US or Canada (custom might not release the phone). A second think you can do is go to several stores and search for cordless phone that does not have the "DECT" logo or technology, then you need to test the phones with an RF meter (like the CORNET ED78 or even the simple ED7 if you can find it) and make sure the phone base station does not emit RF radiation all the time. In general, some of the old cordless phones, that does not support several handset units and work with 27Mhz, 900MHz, and 2.4GHz may prove to be "low radiation". Please send me the link to the eStore so I can take a look and try to guess if the phone in question is not an DECT phone. I am sorry but this is the only way. If you do find such a modal please let me know (norad4u@gmail.com) and I will alert others. ********************************** Q - Can you help Target Individuals?A - I know a bit about electronic attack of TIs (Targeted Individuals) , mostly from people who contacted me in the past asking for help. From what they told me, all or most of the symptoms they have experienced can be linked, connected or caused by Electromagnetic Hyper Sensitivity - EHS condition. Most TI that I talked with use their cellphone, have a wireless PC and router, use wireless devices and are exposed to RF and ELF daily. Since most people don't understand Electromagnetic Radiation, they don't know that using these devices exposes them to RF and ELF on a daily basis, and don't know that this exposure can lead to health effects and EHS-TI symptoms. They don't connect the dots and don't understand that what they experience might actually be an EHS condition. My recommendations in these cases are the same as to every EHS person, do "The 4 steps program" - know, monitor, reduce protect. Following "The 4 steps program" should bring improvement and ease up the symptoms after a while. After doing these first 3 steps (learning about EMR, reduction of the use of wireless devices and measuring the RF levels in his house) a TI person will be able to use also personal protection such as RF protection hats, Jackets and pants and some home protection products such as RF blocking canopies, RF blocking paint, and RF blocking window film. Q - Could you kindly suggest how to shield my house?My main concern in this moment is the wi-fi RF pollution my house is getting from the neighbors and a cell-tower (I can detect 9 different wifi connections from inside my house!!). I disconnected my wifi device, but I would like to find a solution to all these RF signals penetrating my house. A - I suggest you to handle the condition in 3 steps. If you are an EHS person please tell me and I will suggest an additional step: Step 1! I suggest you buy an RF/ELF EMR meter and search for the 'hot sports" on your walls and windows where the RF radiation is entering your house, and also detect other RF and EMR sources inside your house and to replace the RF sources( cellphones, cordless phones, bluetooth equipment and other wireless devices) with device that do not emit any RF and also to make sure no ELF source is located near people. This is the meter I recommend for first use - http://www.4ehsbyehs.com/emr-meters/cornet-ed78s Video of the meter - http://youtu.be/WSDWVALxnDk Info about EMR reduction - http://www.norad4u.com/emr-reduction Step 2! RF from cellphone antenna usually come in to the house from the windows. It is easy to protect the windows either by RF blocking film or RF blocking curtains. RF blocking curtains can be made from most types of RF blocking fabrics - http://www.4ehsbyehs.com/rf-blocking-fabrics Step 3! WIFI can also came in via walls. It is very difficult to block 100% of it but you can reduce the levels by using RF blocking paint or RF blocking wallpaper. The wallpaper is more efficient since it also absorb some of the radiation when the paint mostly reflect it.
