Self-reported sensitivity to radiofrequency fields
|
|
Participants - inclusion criteria
|
Two samples will be tested, consisting of 'sensitive' and 'control' police officers.
To be eligible for the sensitive group, an officer must report having often experienced negative symptoms that they attribute to acute exposure to a TETRA radio handset. Only officers who never report such symptoms will be eligible for the 'control' group.
All participants must be over 18.
|
|
Participants - exclusion criteria
|
Exclusion criteria will include: pregnancy, medical or psychiatric illness where current symptoms cannot be excluded, and current use of analgesics.
