Radiation Detected!

2/14/2010 - Radioactive Items Found in My Home!

Unfortunately it has been some time since I have run into anything radioactive outside my home, however, I thought it would be interesting to measure items inside my home that I have collected, found on eBay or bought in thrift or antique stores.  Many of these items may be found in your home or at garage sales.  I have also finally included more photo's to my site.  Instead of posting the finds to my blog, I have created a new page, click here to view...

Nowadays it is abnormal for any dinnerware to be radioactive. The uranium glazed plates all will register strongly on a geiger counter. As for the radiation killing bacteria, only the weak bacteria. Just kidding, it actually takes quite a bit of radiation to kill most bacteria, much much more than a human being. Food irradiators typically will expose food to 1,500 Gray to 70,000 Gray over the course of 1 hour, it only takes 6 to 10 Gray in one hour to kill a human. To give an idea of scale, 1 Gray is roughly 100 Roentgens, and typically the radiation levels I am measuring are in the microRoentgen/hr range (1/1,000,000 of a Roentgen/hr). So, is the radiation from Fiestaware dangerous? In my humble opinion, no. The greatest danger is from the chemical properties of the Uranium glaze, and that is minimal. If one serves acidic food (salsa, Tabasco, vinegar) on a Fiesta plate, or any uranium glazed plate, they stand a chance of ingesting small amounts of uranium. Uranium is about as toxic as lead, but will not leach into food anywhere as easily as lead. So, in practice, one may not want to use a vintage fiesta bowl to serve salsa, it would be in poor taste. Normal foods, eggs, steak, cereal and milk, all are safe with uranium glazed plates, dishes and bowls. So don't fear your table settings! More than likely unless you have pre 1977 Fiesta plates, they are not radioactive. However, if you have older Fiesta, Bauer, Parma plates, treasure them, they are collectable, and are safe for everyday use.

Very interesting site. I especially liked your report on 2/14 - Items in Your Home. Especially the Fiesta plate. I was surprised it was that high. Is this normal? Will the radiation in the plate kill any bacteria?
