Uh, if what I'm planning on doing with a smoke detector is illegal, please point me to the law. Note that I could supply calibrated detectors, so if I can do it, if it's "fine for me," it can be done "for my customers." If I buy SSNTDs, in whatever form, cut them up and serialize them if necessary, use an Am-241 source from a smoke detector to expose a corner under conditions where every detector receives the same exposure, I *am* the manufacturer. Do I need some kind of license?
I am not going to provide legal advice other than to say you need professional legal advice. There are both federal, state, and local laws and regulations with regards to sale, transport, disposal and specific use or planned use by isotope kind and quantity. Licenses, or license addenda, can (and are, depending on location and conditions) be required for individuals, companies, laboratories, individual rooms in laboratories, and specific planned experiment type including specifics regarding each type of isotope used or planned to be used. Requirements change. It is important to keep up with them. That is why professional advice is needed.
