Is All Emf Radiation The Same
In short, no.
In fact, there are three different kinds of electromagnetic radiation:
Natural EMF is just what it sounds like. It’s naturally occurring. Natural EMF frequencies can come from two different phenomena:
Low-frequency EMF frequencies come from electrical sources like power transformers, high voltage cables, and home appliances.
On the other hand, high-frequency EMF frequencies come from modern communication equipment. This includes devices like mobile phones, Wi-Fi routers, and laptops.

How To Survey A Person
Using the instrument:
- Move the “F/S” switch to “F” .
- Set the instrument selector switch to the most sensitive range of the instrument.
- Holding the probe approximately 1/2 to 1 inch from the persons skin, systematically move the probe across the entire body from head to toe on all sides. Try to maintain a consistent distance.
- Move the probe slowly .
- To avoid contaminating the probe, do not let it touch the skin or clothing.
- Locate the point that produces the most clicks.
- If the meter reads off-scale, adjust the range of the instrument by moving the range selector switch and pushing the reset button.
- Document time and radiation measurements.
- In general, areas that register more than twice the previously determined background level are considered contaminated. If the accident circumstances indicate that an alpha emitter or low energy beta emitter could be a contaminant, a health physicist should always be consulted.
- Note that some GM instruments cannot detect alpha radiation and some low-energy beta radiation. Because alpha radiation is non-penetrating, it cannot be detected through even a thin film of water, blood, dirt, clothing, or through probe cover.
Ending the radiation survey:
- Replace the cap on the meter probe.
- Take the batteries out.

What Are Emf Measurements
EMF measurements refer to the number of electromagnetic fields that are surrounding an EMF probe or sensor. An EMF detector is a particular kind of sensor. So, an EMF detector can take EMF measurements.
In fact, the measurement of surrounding electromagnetic fields is what the device uses to differentiate high levels and normal levels. In other words, the device calibrates itself to its surroundings to find abnormal values.
In order to get accurate results, the user of one of these measuring devices should ensure that the probes aren’t disrupting the electromagnetic field. If this happens, coupling and reflection could follow. This would alter the results of the measurement and render the device ineffective.
When used properly, EMF meters and monitors can perform two kinds of EMF measurements:
We can find broadband measurements by using a broadband probe. Usually, these devices have three independent diode detectors. Broadband probes can sense a wide variety of signal frequencies.
On the other hand, frequency-selective measurements allow the user to test for particular signal frequencies. These devices have a field antenna and a receiver or spectrum analyzer. The receiver/analyzer is the piece that makes it possible to test for a range of different frequencies.
EMF probes can respond to electromagnetic fields on one axis or three axes. Tri-axial EMF probes can show measurements in three directions at once.

Government Researchers Have Developed An App That Turns An Ordinary Smartphone Into A Radiation Detector By Using The Built In Camera To Detect Gamma Rays
Theres an old story about an old photojournalist who, when asked his opinion about the best camera, said the one you have on you. The same might also be said for radiation detectors. Like cameras, these devices tend to be expensive, bulky and likely to be left at home or the lab when suddenly needed.
That could change in the near future thanks to the work of Joshua Cogliati and pals at Idaho National laboratories in Idaho Falls. These guys have worked out how to use ordinary smartphone cameras as gamma ray detectors to spot radiation.
They have tested their app extensively in the lab and say that smartphones can not only detect gamma rays but work out the energy spectrum of the radiation, calculates your radiation dose and may even be able to work out the direction of the radiation source.
In theory, electronic cameras in cellphones ought to be able to detect gamma rays in the same way as they detect visible light photons. These cameras detect light when incoming photons hit electrons inside a pixel, creating a charge that an electronic circuit can then detect. The pattern of charge across the pixel array corresponds to the image.
Gamma rays are high energy photons that also ionise electrons. So they too ought to be detectable by the sensors in smartphone cameras.
Gamma rays have far more energy than visible light photons: for example, they might have 20,000 eV compared to between 1.77 and 3.1eV for visible light from red to violet respectively.
How To Measure The Emf In Your Home Using An Emf Meter
Once you have a high-quality meter, such as the Trifield TF2mentioned above, measuring EMF levels in your home is very easy. To measure EMFlevels, turn your meter to the desired setting and move slowly around yourhome.
Youll want to be certain that you check EMF levels inplaces where you spend a lot of time. For example, be sure to check the EMFlevels near your bed because you probably spend the most time there each day.
Using a notepad or a piece of paper, take note of thereadings in each of the rooms of your home. If you notice that the reading isparticularly high in one of the rooms, see if you can locate the source of theEMF radiation.
As a rule, EMF levels will be stronger nearest the source ofthe radiation. So, for example, if you were to take a reading near yourwireless router, you would probably notice especially high EMF levels. As youmove farther from the source, however, the strength of the radiation becomesweaker and you will notice the EMF levels fall.
Through checking the EMF levels of your home with thismethod, you can become aware of any concerning sources of EMF radiation in yourhome. For example, you may realize that a wireless router or smart meter iscausing high EMF levels near your bedroom.
If this is the case, take proper steps to attenuate theradiation by using proper building materials, or try to locate theradiation-causing device farther from your bedroom.
