The Minister referred to the frequency range. It is true that we are talking about lower frequencies than the ionising radiation that would be beyond the visible spectrum. However, it is not true to say that all low frequencies are not harmful. Looking at microwave radiation, for example, if we get a high enough intensity of non-ionising radiation we can still cause harm. I would not want to be in a microwave oven and I am sure the Minister would not either. So it is not just about frequency; it is about the intensity of the radiation.
