TETRA

TETRA stands for ‘Terrestrial Trunked Radio’. It is the secure radio communications system used by An Garda Síochána, Civil Defence, Irish Coast Guard, Ambulance Services, and soon the Irish Fire Service, and has been in operation since 2006.

Both the handsets used and base-transmitters are more powerful than normal mobile phones “to give a more secure mode of communications”.

TETRA is potentially dangerous because the system emits electromagnetic pulses at 17 Hz, a frequency which is known to affect brain activity.   https://www.powerwatch.org.uk

TETRA can produce the specific ill health symptoms caused by similar radiation. These include: cancers, cardiovascular effects (e.g. irregular heartbeat, shortness of breath, stroke), hypersensitivity to electromagnetic energy, neurological effects (e.g. sleep disorders, dizziness, nausea, headaches, migraine), reduced fertility, and skin effects (rashes, itch).
