Radium is a chemical element with the symbol Ra and atomic number 88. This sample is an antique radium clock hand.  The radium no longer glows but is still slightly radioactive. This sample is safe. The amount of radiation emitted from this cube is less than what you would receive on an airline flight.  It is also legal to ship internationally due to the fact that it is an antique. 

Radium is the sixth element in group 2 of the periodic table, also known as alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas (specifically the isotope radon-222). When radium decays, ionizing radiation is a product, which can excite fluorescent chemicals and cause radioluminescence.

Please note that this item might be classified as hazardous material in certain countries. We suggest checking local guidelines to ensure compliance before placing your order.

Safety

We get asked about the radioactivity and overall safety of the periodic tables/cubes from time to time. These are legitimate concerns and we wanted to address those concerns here. Although there are several elements in the cubes that are dangerous or toxic, the acrylic and glass ampules make the products safe to handle and store.

The average American is exposed to 0.034 mrem/hr from background radiation (300 mrem/year). In other words, a person will get three times the radiation from natural background radiation which includes the sun, food, radon, and the environment, than they will from holding a radioactive element in one of our Lucite Acrylic displays.

Care Instructions

Wash with mild soap or detergent and lukewarm water. Use a clean, soft cloth, or sponge. Rinse and blot dry with a damp cloth or chamois.

*Never use abrasive cleaners, household cleaners, window-cleaning fluids, scouring compounds, gritty cloths, or strong solvents such as alcohol, acetone, carbon tetrachloride, etc.*

To maintain the brilliant luster of acrylic, wax and occasionally with a quality grade of automobile paste wax (NOT A CLEANER WAX COMBINATION.) Apply a thin coat with a clean, cotton flannel cloth. Then wipe with a clean damp cloth. NEVER USE HOUSEHOLD SPRAY WAXES.

Proudly made in the U.S.A.

Cube ok, not shipped by DHL despite offered

The cube is fine and nice. But I avoid UPS as a delivery even if it costs me more. I was happy at first that they offered a shipping method via DHL, so it seemed. But it still got send via UPS. Now I feel kinda scammed that I paid double the shipping cost.

On behalf of the Radium cubes...

If this company is using the radium that was applied on the watch hands during the radium watch era, you are most indeed getting radium but on leftover parts, so they're all gonna be different in ways. I'm just throwing it out here. We don't really use radium anymore, watch parts are probably the easiest and honest way to put the element on display. Just throwing it out there. It's still awesome.
