711-12B Filmguard Bag - Medium, black

I bought this Domke film protector bag for an unconventional purpose — to store a collectable piece of Bauer Pottery from the 1930s, 40s, or 50s which has an unusually-high uranium content in its glaze (to give it the burnt orange color). Check out how much the Domke storage bag reduces the radiation levels when tested with a Geiger counter (see video). IT WORKS!!! And it is very well made as well… Background Story: I had helped my daughter do a science experiment a few years ago when she was in 7th grade. We tested typical household items — such as bananas, iodized salt, and granite countertops — for the small amount of radiation content that they may have. We also tested collectibles — like “uranium glass” (green glass) cups and plates, and Fiestaware and Bauer Pottery. The Fiestaware got a medium CPM (clicks per minute) radiation count, but the Bauer Pottery burnt orange glazed plate tested off the charts! From 1936 through 1943 it was typical for the “Fiesta red” Fiestaware (the burnt orange color) to have uranium in the glaze — up to about 14% natural uranium content. That was later changed to “depleted uranium” from 1959 to 1969 (still radioactive), and, according to our research, continued to be used in some of their products until 1973. Important: Any *modern* Fiestaware is perfectly safe and does not use uranium in the glaze. If you have vintage Fiestaware, typically only the “Fiesta red” (burn orange) glaze has higher levels of uranium (but it’s still just a fraction of the Bauer CPM levels we were getting). From what we’ve read, the “Fiesta yellow” glaze *might* have a small amount of radioactive content as well, but in our tests of vintage Fiestaware, only the “red” glaze seemed to have elevated levels. Lucy’s findings in her science report were that none of the household items (bananas, etc.) tested particularly higher than typical background radiation levels in our homes. Uranium glass got a small rise in levels; the “red” Fiestaware slightly higher still, and Bauer was quite high as you can see in our video — worryingly so! Our Conclusions: Any of the items we tested — including the Bauer — would be perfectly safe to have on a shelf or in a collectibles display if you were more than about 24 inches away. However, Lucy and I both concluded that we would not want this Bauer plate in a display cabinet, let alone eat off of it, or certainly not sleep with it under our pillow! ;^)) All of this is unrelated to the Domke storage products, but it should illustrate how the storage bag is likely to function for its intended purpose for protecting photographic film from X-rays!

Works great. So far most airport staff are aware of this product and doesn't make a fuss when it goes through the scanner. Will request you to show them if they are required as per the airport's security requirement. If no - they'll just take a quick peek and move on.

Mi fido delle recensioni e spero funzioni. Ci entrano fino a 16/17 rullini.

Super Hochwertige Haptik, tolles Produkt

Perfect size for the rolls it says it holds. Might be even enough for a small point & shoot.
