A notorius element in the Periodic Table of Elements known for its radioactivity and role in early radiotherapy. Was first discovered by Marie Curie at the dawn of the 20th century. Though killed by her dangerous endeavor to discover radium by chronic radiation exposure, radium has served to save many cancer patients's lives.
PatientIn1901: Good god this radium patch burns! At least it's better than dying of skin carcinoma...

DoctorBehindLeadShieldOverMicrophone: Just relax. After several months, your cancer should be in remission.

A very radioactive alkaline earth metal that used to be found on glow-in-the-dark watch dials. They were covered with luminous paint that contained a small amount of radium.

Eventually people figured out that radium paint is a pretty big health hazard, so they stopped producing watches with it in the 1970s.
Person 1: Yo did you see that movie Radium Girls?
Person 2: Yeah, it's pretty depressing how they kept getting poisoned from being forced to paint the watches with that stuff.

Greeting Radius 

The distance of your radius that you will acknowledge the people you know and greet them. Greeting radii almost always depend on person. Usually, your greeting radius varies based on how much you like the person. Someone you are close friends with, will probably have a greeting radius of over 50ft. For people you don't like, it would probably be something like 10ft if it's crowded where you are.

Steve: Yeah, GOD today was a bad day

underpants radius 

The distance a man is able to comfortably travel (from his bed) without pants; the average radius being just the distance to the shower.

It is theorized that a man's underpants radius is inversely proportional to his confidence; that is, the farther a man travels from his bed in just his underwear, the less he believes in himself.
At first we thought it was funny; at least Marshall didn't left the house without putting pants on. But his underpants radius just kept getting larger. He started getting the paper in his underwear and even going downstairs for a drink in his underwear...!
