Source control
The simplest intervention is often to remove or disable an unnecessary source. This is directly testable and costs nothing when practical.
Distance
Field strength generally changes with distance, although the exact relationship depends on the source and environment. Moving a transmitter away from a bed or desk can be a simple first experiment.
Shielding
Shielding can work when the material, frequency, geometry and installation are appropriate. Poorly designed shielding can be ineffective or create unintended behavior, so measure before and after.
Measurement tools
An EMF meter can be useful when matched to the field type and frequency range. Consumer meters have limitations, but they can help verify whether a source-control or shielding change affects the measured environment.
Harmonizer-style devices
Products such as Somavedic belong to a different conceptual category. If the product does not claim to reduce the meter reading, evaluate the alternative claimed endpoint and supporting evidence instead.
