The electric and electronic devices, used frequently nowadays, cause fields around them.
These fields can range from half a meter (for small magnetic fields) to several
kilometers (for electromagnetic fields caused by broadcasting masts for mobile phones).
The technical and health issues of these fields are discussed in the information part of this website.
Envionic sells devices to measure these fields. The measurement of the strength of low frequency electric and magnetic fields as well as high frequency electromagnetic fields is possible.
