I've heard about it from multiple sources, and it's only a problem when I'm near items that are on and emitting electromagnetic radiation. I've never had any sort of seizure activity before, but with this new sensitivity, I could see that it might be capable of causing seizures. I just began a homeopathic detox regime to neutralize the radiation that's in my body. So far it has improved my thyroid function, but I've only been on it for a day.
