Hi guys, this is my very first message at this forum.

i have a dental x ray head machine, to use in my experiments. I would like to perform fluoroscopy and developping x ray films to study x ray diffraction of my minerals, according to the Laue methode.

im engaged in build a effective lead shielding, wich is compound of 4mm sheets directly on the head. I would like to know if it is enough for a effective shieldeing. I have made many researchs eand calculations but i would like to get your opinions. Thanks a lot.

If you know this little about shielding you definitely should not be screwing around with a used X-Ray unit.  I HIGHLY recommend that you dispose of it properly before you hurt yourself or others.

The attenuation coefficient for lead is easily found with a search. It’s a function of energy, so you need to know that.

One solution, of course, is to not be in the room while the machine is on, just like the dental folks do it.

You could share that.
