The EMF Radiation Detector - Magnetic Field Detector is the best app if you want to detect Electromagnetic field in your surroundings.

EMF Radiation Detector - Magnetic Field Detector App measure and study magnetism and electromagnetism, the earth’s geomagnetic field and more. It can be used as a detector not only for EMF but also for magnets, metals, devices etc.

EMF Radiation Detector - Magnetic Field Detector is quit handy to use even its detect electronic devices because those devices emit EMF radiation and electric field.
guass meter - emf radiation detector - electromagnetic detector is the best choice for detecting EMF activity around you.

The EMF Radiation Detector - Magnetic Field Detector uses android phone's sensor called magnetometer to detect Electromagnetic waves around you.
EMF measurements or measurements of radiation, electromagnetic fields that are performed using particular sensors or probes such as EMF Meters.

Radiation or eavesdropping particle detector is a device that measure this ionization of beta radiation, gamma radiations and alpha radiation with matter which create electrons and positively charged ions.

Electric and Magnetic Fields (Emfs) are invisible areas of energy, referred to as radiation that are associated with the use of electrical power. Emfs are typically grouped into two categories by their forms of frequency:

Non-ionizing Radiation : This is low-level radiation which is generally perceived as harmless to humans.

Ionizing Radiation : This high-level radiation which has the potential for cellular and DNA damage.
1- Non-Ionizing Radiation:
✔ Extremely Low Frequency (ELF)
✔ Radio Frequency (RF)
✔ Microwaves
✔ Visual Light
2- Ionizing Radiation:
✔ Ultraviolet (UV)
✔ X-Rays
✔ Gamma
Electromagnetic fields are energy area which created by electronic devices there are two parts in fields. (1 electric 2- magnetic).
Electric field is created by differences in voltage and the magnetic fields are created when there,s electric current running to a device.

EMF Radiation Detector - Magnetic Field Detector also detect electronic devices like Cell phones,laptop,wifi,network devices etc which emit a form of radio frequency radiation at the lower end of the non-ionizing radiation spectrum.

How To Use EMF Radiation Detector - Magnetic Field Detector
EMF Radiation Detector - Magnetic Field Detector app is easy operate and portable with auto-detection function called detect radiation or EMF with analog meter.
When there are some emf field,eavesdropping devices,radiation it will give alert beef sound.

Radiation Meter - EMF Detector - eavesdropping detector this application is easy to use, just open Detector app and move it around the suspected objects.
If the magnetic field values arises then there should be Radiation devices, hidden microphone or cameras in the area your surroundings.

Important Note: To Detect Radiation,EMFs,Magnetic field,Radio Frequency you must have electromagnetic sensor in your android app.
