I am currently working on a low energy particle accelerator. Its main purpose would be to produce low energy (few keV) electrons and metal ions for high precision non radioactive isotope selection. I've already dealt with the radiation of the accelerating charges and they are unlikely to produce a non negligible amount of harmful radiation. Besides these things the radiation will be monitored and the machine will be shut down if it is not working correctly.
Now that I made clean that I'm aware of what kind of security this machine needs I want to ask you: Do I need any precautions to start experimenting or do you have an advice? I just want to make sure that I don't do anything wrong. I'll post a simplified scheme of it if it's needed.
