So, I was thinking about building a low power klystron (around 5W.) I know this involves making an electron gun and electron guns can emit x-rays. I have a few questions: 1. Will 5W produce x-rays? 2. If so, what is a safe dosage of x-rays? 3. How can I shield myself and others from the x-rays produced? The x-rays are an unwanted side effect.
