Hi, please advise me, I am going to buy a small dose x-ray machine for dental filming in dentistry, it is said that they are all 0.5mA, I do not know how to protect the filming room

Hello, I am specialized in dental technicians. I don't know whether the small-dose dental film machine you bought is the kind of portable X-ray dental machine (similar to a camera), or the dental machine to be installed into the room. If it's one of those small cameras, you don't have to use a lead room because it requires personnel to operate it directly and wear lead clothing. If it is a normal installation of X-ray dental machine, to install the lead room, lead room of the lead plate thickness is generally about 2mm, there are specialized in doing lead room, you can directly consult. Dental film machine 0.5ma mA, ma number is a little small, you buy before you try to film the effect, especially to shoot the back teeth. What needs can be asked directly, I hope you can give points.
