Health effects	- Subjective report of symptoms/physiologic reactions.	- Subjective report of symptoms/physiologic reactions.

	- Subjective report of being sensitive to specific or various EMF sources.
Cognition & behavior (optional)	- Symptoms occur during or after the individual perception or actual exposure, presence or use of an EMF source.
