Is radio frequency radiation dangerous?
There is a wide range of types of radiation. Ionising radiation like X rays and gamma rays is dangerous as it can break chemical bonds and damage DNA. RF radiation is low frequency and non-ionising so it cannot do that. The only known effect is heating. The heating effect from a TETRA handset is very small, and much less than the natural variation in body temperature that occurs throughout the day. Larger heating effects can be dangerous for example microwave ovens emit non-ionising radiation but clearly have a substantial heating effect to cook. ICNIRP sets exposure limits designed to protect us and TETRA handsets operate well within these limits.
