Scientific title
Study objectives	Exposure to pulsed TETRA radiofrequency fields will be associated with higher symptom reporting than exposure to unpulsed radiofrequency fields or sham exposure.
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Self-reported sensitivity to radiofrequency fields
Intervention	Each participant will be exposed under double-blind conditions to three exposures in a randomised order: pulsed TETRA radiofrequency fields, unpulsed radiofrequency fields, sham exposure with no fields present. Each condition will last for a maximum of 50 minutes.
Intervention type	Other
Primary outcome measure	Self-reported symptom severity during exposure.
Secondary outcome measures	Comparison of the two groups in terms of general health and autonomic nervous system function.
Overall study start date	21/10/2005
Completion date	30/06/2008

Participant type(s)	Patient
Age group	Adult
Lower age limit	18 Years
Sex	Both
Target number of participants	120 participants (60 sensitive and 60 control)
Key inclusion criteria	Two samples will be tested, consisting of 'sensitive' and 'control' police officers. 1. 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. 2. Only officers who never report such symptoms will be eligible for the 'control' group 2. All participants must be over 18
Key exclusion criteria	1. Pregnancy 2. Medical or psychiatric illness where current symptoms cannot be excluded 3. Current use of analgesics
