Nice! I collect radioactive stuff! That pitcher contains Uranium Trioxide (UO3). The decay products from Uranium-238, and to a lesser extent, Uranium-235 are in secular equilibrium. Protactinium-234, Radium-226, Bismuth-214, Lead-214, and some from Actinium-228 and Thallium-208 produce gamma rays with characteristic energies. At 1:55, it's not that yellow pitcher. It's the orange salt shaker or candle holder in front that also has the UO3 glaze. :-)

Cool !!!

crap been eating off those orange plates for years probably lead too in ceramic glaze from stuff made in the 70's

Counts per minute is a weird unit that doesn't really tell you anything. Mine registers microsieverts per hour. My normal background is 0.1/hr. With the alpha/beta shield in place (gamma only), my plate registers 1/hr. With just the alpha shield in place (beta + gamma) it registers 8/hr. And with no shield in place (registering all 3) I'm registering 40/hr. So total of about 400x normal background. Mostly alpha, but enough beta to let me know that my plate is a 1936-1942 one (made with natural uranium). The ones from 1959-1972 were made with depleted uranium, and have much less beta/gamma than mine.

Completely agree. CPM doesn't really tell the whole story. It is a mix of all types of radiation and the count you get is completely dependent on the size of the sensor. I over this in one of the earlier videos in the series. This is a whole series of videos where I am comparing the relative CPM for different items.

I really want to get some radioactive fiesta ware for teaching about how radiation works. I am also pretty concerned about these plates. In the video you don’t seem to be concerned and I haven’t seen any reports of why you shouldn’t have fiesta ware if you don’t eat off of it, But just as a question is fiesta ware dangerous if you just don’t eat off of it and have it as like something to demonstrate how my Geiger counter works

@@gold_monolith6816 It's not dangerous at all, to have or even hold. I probably wouldn't use it as a pillow. I also wouldn't eat off of it, because 1) acidic food could potentially leech uranium out of the glazing, and 2) these plates are OLD, so there is the potential for the glazing cracking/breaking, and you do not want to ingest it.

Do they glow under UV light?

Does it put out gamma?

Yes, it is radioactive from uranium so it emits gamma.

are these things dangerous?

Not really. They don't sell the radioactive ones anymore but it is fine to collect. Some people recommend not eating of them. One philosophy is that we should minimize all contact with radiation just to be on the safe side so from that perspective, sure, keep away. In reality though we are bathed in natural radiation all day and having one of these up on a shelf isn't going to kill you.

Interesting, some of that could be from the small piece in front. I think the yellow did give off a small reading though if I recall.

No just dont smash it on the floor and huff the dust from it and you will be fine the radioactive material is safely put in the glaze. Eating off of this plate is no more dangerous than going to the beach and getting a suntan it just comes down to if the radioactive material is getting Inside of you that's when it becomes dangerous.

A lot of the glazes are so hot because the radium and daughter products of uranium were left in the mixture.

Mr.Microcuries Interesting. My impression was that a lot of the uranium ore used has already been stripped of Radium for use in industry and the ore was cheap because it was essentially a waste product. I suppose sources could vary depending on manufacturer. Certainly even if there were no other elements present at the start they are there now as daughter particles created through decay. With gamma spectroscopy we could see the exact ratios of each present. I don’t have access to the equipment though as it is quite expensive.

The truth is that everything in your home gives off some radiation. Only the original "radioactive red" was made from depleted uranium oxide ore. The radiation from one dental xray is equal to having that pitcher strapped to your chest for years. I've been collecting for nearly 50 years and do use it to eat off of on special occasions. What the expert also doesn't know is that several of the pieces shown were made since the re-issue in 1986. Not only are they not radioactive but the new glazes are lead free. That is the real danger if you used the vintage every day the glaze breaks down and leaches lead. Very, very low levels of lead.Not dangerous.

While you are correct about the Fiestaware not being dangerous your statement that everything in your house giving off some radiation is incorrect. Atoms with atomic numbers greater than 83 are radioisotopes, those with lower numbers are not. So, items in your house that do not contain atoms with atomic numbers greater than 83 are stable and do not decay into other elements.

My two small pieces of broken fiesta-ware give off about 15 microsieverts an hour, that's a lot more than one dental x-ray which is around 5-10 microsieverts per x-ray
