Lead. As near pure as makes no odds.
Silver is pretty worthless at stopping Xrays.
Yeah but silver is used in xray film. This is the film backings so think you're right.
Sheepdog, as mentioned, I believe you meant to say XRay film shields they put in your mouth. Having melted several hundred pounds of it and tested for hardness ... it ranges for Bhn 8.2 or 8.7. That's close to 1:30 amd 1:20 alloyQuote:
Dental xray film
Is this lead or silver?
The removable foil backing is lead.
my daughter is saving it for me at the dentists office she works at.
every dentist office i have talked to so far say they use digatal and have no lead foil.
My wife is an assistant and she says pretty much all offices are going to digital and there won't be film (or lead) much longer.Quote:

I have two offices , one is my Dentist & the other a friend works at, are saving their peel off's for Me. When I get a bag full I drop back with a dozen fresh donuts , & the supply just keeps on flowing... When they go digital then I guess there donuts will also go away. My 2¢. Russ.
BTW someone asked for the MSDS sheets on this and they came up with the percentages of alloys..... Lead 95-96%%, Antimony 1-2%, Tin 1-2% (Aprox guess)
It was in a post not too long ago.
