Dubnium Cube Element

$53.55
Shipping calculated at checkout.

Dubnium's atomic number is 105 and its symbol is Db, and it does not occur naturally on Earth, so it has to be produced artificially. It is highly radioactive; the most stable known isotope, dubnium-268, has a half-life of about 28 hours. This has greatly limited extended research on dubnium. Two different groups claimed to discover the element around the same time, both proposed a different name for the element. After years of dispute over the naming of the element, it was named after Dubna, a town in Moscow, Russia, where one of the research groups that discovered it was located. This display is contained within crystal clear Lucite acrylic.

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.
