3 Radioactive Plates 2 Mantles Geiger Counter Test Lot!

A message to eBay: Please look at my regulatory statements made below to assure that there is no legal or ethical issues regarding the possession and transfer of these items.

This is a multiple item lot. The item titles are in bold, descriptions follow. Last chance on some of these items! My stock is dwindling!

#1 This is a very nice, VERY RADIOACTIVE specimen, a very rare AUTHENTIC FIESTAWARE plate in radioactive red (Picture 3). It puts off a very respectable 62,000 counts per minute... (Always with a calibrated Bicron Surveyor M with 44-9 Pancake Probe, so it's combined alpha/beta/gamma reading.) That's a hot plate. It's beautiful, in very good condition, with a few very minor scratches and blemishes, as it was used for several years. There are some minimal marks and imperfections like nearly all the plates from this era, if you have purchased these before you know what I'm talking about.

#2 This is another very nice, VERY RADIOACTIVE specimen, an excellent Gladding McBean plate in radioactive red (Picture 2). It puts out an incredible 77,000 counts per minute... (As always, calibrated Bicron Surveyor M with 44-9 Pancake Probe, so it's combined alpha/beta/gamma reading.) GMB plates are unique because the glazes are very deep and very smooth, thicker than the glazes on Homer Laughlin plates, so there aren't a bunch of obvious thinner or thicker spots on the surface. This plate is almost perfect... The 3 marks forming the triangle on the bottom of the plate are from the stand it was placed on when it was being fired, all glazed plates have these. Other than that, it's absolutely flawless. Plate up for bid is the actual plate pictured.

This will make a GREAT geiger counter test source, class/science demonstration, or collectors item, and it is SUPER RADIOACTIVE! You'll love it.

#3 Relisted for you after clearing up some regulatory issues, this is a RADIOACTIVE, 8 inch (estimated) dinner plate made (Picture 4) with a type of glass similar to depression/vaseline glass, although it lacks some of the characteristics... First off, it's perfectly crystal clear. Second, it doesn't glow under UV light. Still, it has that beautiful yellow uranium based color, and it is radioactive. It puts off about at least 2400 counts per minute (on my Bicron Surveyor M with 44-9 Pancake Probe). It'll make a great test source for a geiger counter or a great part of a collection of hot items. This item will appeal to people who need a source that puts out more gamma than normal, like those with gamma scintillation probes or people who want to experiement with those...

This item is unique because of the abnormally high proportion of gamma radiation that it puts out. It puts out a little less than three times the gamma that a 61,000 CPM fiestaware plate puts out, while this item still only puts out about 2400 counts per minute combined on a standard pancake probe.

Fiestaware plate: 61,000 CPM combined on pancake probe, 8,000 CPM gamma only on a gamma scintillation probe

This plate: 2400 CPM combined on pancake probe, 21,000 CPM gamma only on a scintillation probe

That is a seriously HUGE proportional difference, bordering on EXTREME. If you need further explanation or clarification, please don't hesitate to ask. I don't know why this is the way it is, if you know please tell me! perhaps the colorant has a higher proportion of radium than average? Regardless, it was a big surprise to me. All scintillation probes are different, so the specific count rates may be more or less depending on your equipment. Just know that the amount of gamma radiation relative to alpha and beta was much higher than normal.

This plate is used and has some light, almost unnoticable knife scratches and such. It has no brand or markings on it, and is therefore not something that I can trace or get any more details about. It appears that it was used for many years, although it is still in fantastic condition. It really is a very beautiful item. The picture doesn't do it justice, it's fantastic.

#4&5 Here we have two thorium lantern mantles included in this package (Picture 1). The Thorium content makes it nice and radioactive. It's about four inches high. It's new, unused. AT LEAST 7,000 counts per minute on surface, about twice that if folded in half. That's on a calibrated Bicron Surveyor M with 44-9 pancake probe, as shown in the picture on the x10 setting. Mantles vary slightly in activity. Every mantle will be checked before shipping to ensure that it is at least 7,000 counts per minute, surface reading, unfolded and out of the bag. These are very high quality mantles and are hotter than most others that I have seen on the market. You'll enjoy this very high quality item. Please note, if you're using a CDV 700 Geiger Counter, your count rate will be lower. I don't know how much lower it will be, because most of those counters out there are not properly calibrated.

Please check my other auctions for unique and rare radioactive items. Because I sell just a few items, I'm able to ship the items on the next business day after receiving your payment. Exceptions are rare, but you will be notified if there's going to be any sort of delay in getting the item out. It has never taken me more than two days to get an item in the mail.

Please note that there is NO INTERNATIONAL SHIPPING under any circumstances, as regulations for shipping these items only cover the United States of America. Insurance is $1.70, and is required on this auction because of the high volume of breakable items. I pack VERY well, but I can not be held responsible for what happens in the mail.

Message to eBay: This item will be sent in compliance with guidelines specified in USPS Publication 52, and will be shipped in a manner compliant with 49 CFR 173.426.

This mantle is new, unused and undamaged. No returns on this item. This specimen is safe to handle and use. I wouldn't recommend taping it to a pregnant womans belly or attaching it to a belt buckle, but it's still fairly safe. Not for use as a prophylactic device, despite its appearence. Geiger counter is not included, obviously. Your measurements may vary, as you will be using a different counter and probe. I do use calibrated equipment to measure the activity levels.

Paypal only. USPS will be used for shipping most of the time, although I reserve the right to change carriers. This item will be shipped within all regulatory standards. This item is legal, exempt from NRC licensing. Shipping and handling is 3.95, insurance is optional, but it's not likely that this item will be damaged in transit. Still, I can not be held responsible for what happens during shipping, so it is up to you.

No reserve, please don't hesitate to bid high, says me!

To answer a couple of new questions (and one old one) that were asked, I'm revising the post...

1. "are the plates just the 1s that noone else wants?"

Answer: No, this specific auction is a package filled with high quality items that was going to be shipped to a gentleman in New York. He bought these items from me on another trading venue that doesn't have the safety and security benefits of eBay. I was never paid for it... Instead of unpacking and selling the items seperately, I figured that somebody on eBay would really want this set exactly like it is.

2. "will you sell the items separatly? how much would that be?"

Answer: I'm starting to put up individual items again, and I do have some similar items that will be auctioned very soon. If you have something specific in mind, email me and I'll let you know if I have it.

3. (a question from a previous auction) "sir, im looking for some of this stuff in mint condition do you have any of those in your collection?"

Answer: Yes! The majority of my items are in good or very good condition. Aside from that, I usually sell my collector quality items in person, because it's very difficult to determine the quality and condition via photographs only. My current collector quality plates are 8 and 12 inch radioactive red California Pottery plates in near mint. I'd be surprised if anybody is interested in them, but they do exist.
