Pedantically, we could say that your house is literally bathed in radiation day and night, since visible light is radiation, and so are the infrared wavelengths coming from your radiators and the 2.4GHz frequency radio waves from your home Wi-Fi and mobile phone. But what you’re probably referring to is ionising radiation – the kind powerful enough to knock electrons out of atoms and thereby cause cancer and, at very high doses, radiation poisoning and burns.
