| Primary study design | Observational |
|---|---|
| Study design | Randomised controlled trial |
| Secondary study design | Randomised controlled trial |
| 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(s) |
Self-reported symptom severity during exposure. |
| Key secondary outcome measure(s) |
Comparison of the two groups in terms of general health and autonomic nervous system function. |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Adult |
| Lower age limit | 18 Years |
| Sex | All |
| Target sample size at registration | 120 |
| 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 |
