Fortunately for us, Harry has listed a couple of dos and don’ts for those who are tempted to try this experiment at home (don’t tell me you’re not interested, reverend tethercow.com)
Whenever the machine is in operation, the experimenter must wear a lead apron and stand well behind the orifice through which the rays are emitted. Never turn your back on the machine so that you are between it and the apron! It is also advisable to place a few exploratory samples of film around the room while the apparatus is in operation. When developed, these will show the pattern of radiation and protective lead shielding can be installed accordingly. Finally, resist the temptation to make X-ray examinations of the bones in your hands or other body parts. A frozen fish makes a much safer test object.
