Also, there will be RAM in a D-T neutron generator.....
As a major user of these devices (for downhole petrophysical logging), we are required to register them in our NRC and State licenses, with all the usual inventory, usage and disposal controls.
But a more interesting "twist" is that these are considered "dual-use" items and subject to extreme export controls (probably not an issue in this case.....)

As I mentioned in my previous posting, Colorado requires a radioactive materials license for use of all neutron generators regardless of type. The same rule applies to cyclotrons. The reasoning behind this decision is that radioactive materials are produced as soon as you energize the device. This is usually in the form of activation products (inside and outside the device), but you can also make fission products if that's your intent.
