Which radiation values are considered high and where are they usually recorded? What methods of protection are available if you find elevated prices? The last web page you are going to visit before you buy electromagnetic radiation meters! What do radiation meters measure? EMF (electromagnetic fields) or EMR (electromagnetic radiaton) meters are divided into 3 main categories according to the type of the radiation they measure: Low frequency radiation meters measure electric and magnetic fields from electrical and electronic devices, power cables and transformers etc. High frequency radiation meters measure electromagnetic fields (radio waves, micro waves etc) from cell phones and cell phone masts, wireless internet, cordless phones, bluetooth devices, alarm systems, microwave ovens, wireless game consoles, TV and radio broadcasting antennas, radars, police communications etc. Radioactivity meters measure a and b particles, gamma and X rays from granite tiles, medical equipment, radon gas, subsoil, nuclear accidents etc. Just read on and choose the meter you like! Thinks we consider before recommending a meter? Good luck with finding the manufacturers of some of the cheapest china made meters on the market. All these above factors are analyzed in our high frequency meter, low frequency meter and radioactivity meter guides. Please read them carefully before you purchase! How can i measure radiation from cell towers, cordless phones, Wi- Fi modems, tablets, smartphones, baby monitors, microwave ovens etc.? You will need a high frequency (=wireless) radiation meter which measures electromagnetic field power density (in m. W/m. 2 = milliwatts per square meter = 1. When electrical current flows through the conductors (when there is electricity consumption) AC magnetic fields are also produced. Low frequency meters should be able to record radiation in the frequency range 5. Hz (at least) which is the main frequencies of electrical grids. Magnetic field meters measure magnetic field flux density in n. T (= nano Tesla) or m. G (= milli gauss = 1. T). Electric fields are elevated near high voltage cables, but do not enter the interior of the buildings because they are grounded from most building materials (except from glass or wood). Inside the buildings electric fields are produced mainly form the in wall cables anf the electricl appliances that are plugged in. Low frequency electric field measurements are indicated in areas such as bedrooms, where continuous power supply of devices and circuits is not necessary. Also the presence of high electric fields ia probably more aggravated during night sleep./p> Learn more about low frequency radiation meters, sources and safety limits.. How can i measure radioactivity from building materials, nuclear accidents, medical equipment, radon etc.? The radioactivity or ionizing radiation meters measure the radiation from radioactive materials (subsoil, food, building materials, tiles, granite counters, nuclear accidents, ionization smoke detectors, medical equipment etc.) and from the radioactive radon gas that is emitted from the soil, enters the buildings from pipes and cracks, accumulates especially in low floors with inadequate ventilation and is the most common source of radioactivity exposure. Radioactivity meters Radioactivity meters usually contain a Geiger - Muller tube which records the effective dose rate of radioactivity in . These are separated into water, Ley, Hartmann, Curry lines etc. Their existence today is disputed and / or considered insignificant in relation to strong electromagnetic fields from modern artificial radiation sources (antennas, transformers, cables, etc.). Also, there is yet to be found a scientific commonly accepted way of measuring them. To identify them the main way used is still dowsing by people who have the ability to feel ethereal or earthy fields (radiaesthesis). Some research has been done on the subject (Betz, Hans D .: Journal of Scientific Exploration 8: 4. Recent results on water dowsing / Maes W: Radi. Wohnung und Gesundheit 5. Geobiological Consultant by the German Institut Geo- Baubiologie) makes us believe that this method gives very subjective results. Some claim that they measure geopathic fields with the use of geomagnetometers, however this measurement, especially indoors, detects static fields from steel pipe lines, reinforcement, bed springs and is not related to earthly energies. Is there a meter that measures all types of radiation? So far there are no meters that measure all types of radiation (ionizing and non ionizing), but there are meters that measure the basic artificial electromagnetic fields that are the main part of electrosmog today: low frequency magnetic fields (non ionizing radiation from power lines, transformers etc)low frequency electric fields (non ionizing radiation from electrical cables, devices, etc)high frequency electromagnetic fields (non ionizing radiation from wireless phones, cell phones masts etc)These are called combination meters and their main advantages is that you only need one to carry around for your basic emf measurements and they usually cost a lot less compared to buying 2- 3 different meters to do the same measurements. On the other hand combination meters tend not to perform well in all types of measurements. Some times their performance in specific measurements is really terrible, so try to read their specifications and our comments in the comparison tables before you decide to buy one of them. Read more about combination meters, their advantages and disadvantages. Why should i measure the electromagnetic fields in my home or workplace? The continuous increase of modern day electromagnetic pollution (=electrosmog) makes radiation measurements more relevant and necessary than ever, especially for the most vulnerable population groups (pregnant women, children, elderly and ill people). Measurements of the invisible electromagnetic fields is the only way to determine if the areas where you spend most of your time exceed the proposed limits exposure to artificial radiation due to the presence of visible and invisible radiation sources (mobile phone masts, cordless telephones, and modem- router Wi- Fi, electrical appliances, cables, pylons, transformers etc.). By measuring electromagnetic fields you can significantly reduce your daily electromagnetic burden, by identifying and avoiding electromagnetic hotspots and in many other ways which are detailed in the Home Biology EMF reduction guide.“whereas electromagnetic fields (EMFs) exist in nature and have consequently always been present on earth; whereas, however, in recent decades, environmental exposure to man- made sources of EMFs has risen constantly, driven by demand for electricity, increasingly more specialised wireless technologies, and changes in the organisation of society; whereas the end effect is that every individual is now being exposed to a complex mixture of electric and magnetic fields of different frequencies, both at home and at work” European Parliament resolution on the health problems associated with electromagnetic fields (2. If the mother is sleeping in strong electromagnetic fields the child will be neurologically abnormal. Within 2 years the child will develop all the signs of autism, neurological dysfunction, hyperactivity, learning disorders and so on. Dietrich Klingkchart, Institute of Neurobiology Washington . Too often does a long- term disease or affliction improve or disappear in a relatively short time after reduction or elimination of HFMR pollution in the patient's environment.
