Radium Watch Hand

from THE STEMCELL SCIENCE SHOP

Regular price $7.95

Radium [Ra, 88] is a radioactive element, so it isn't something you come across everyday. But decades ago, it was painted on watch hands since it naturally glows in the dark. This practice was discontinued in the 1960s, and now these old watch hands make a great radium sample for your element collection.
