Locals in towns like Dereel, Buninyong and Cardigan Village have raised concerns over the erection of communications towers in their towns linked to the rollout of the NBN.
They say they are worried the towers will be built too close to houses and that they could emit electro magnetic radiation (EMR) at levels harmful to human health.
But a radiation expert says the available evidence doesn't show there are any significant health effects from living near a communications tower of this type.
