Are Antique Uranium Glazed Ceramics Dangerous? #historicaltidbits

Many glazed ceramic antiques made in the late 1800s and up to World War 2 contain a notable amount of uranium, which gives the spiciest pieces a unmistakable orange color. This glaze largely contains depleted uranium. The piece in this video when measured with a GMC GQ 600+, a device capable of measuring Alpha, Beta and Gamma radiation, estimates around 60 uSv/hour. If one assumes the ceramic is held in the hand for approximately one hour a day, this may expose the hand up to around 22,000 mSv annually, which is 22 times higher than the 1mSv per year recommended limit. But alpha particles are not the only worry. This cup, even within a few feet of you, exposes you to gamma radiation. It quickly drops off with distance, but would add to the overall exposure. Not to mention, any potential of uranium leeching into your beverage should you use it to consume liquids. So while these ceramic pieces are safe to display in a cabinet, they should not be used for drinking or eating to limit overall risk of cancers. Even alpha particles can cause skin cancer.
