What is the definition of Hospitals Light Particles?

"'Hospitals light particles'? Like, did you see those nurses wearing glow sticks? They're not just for ambiance, folks. These hospitals emit particles so potent, they're turning patients into cosmic sparks. And maybe just maybe, they're trying to make room for a new line of 'light therapy' treatments. Or just plain old radiation therapy gone wrong with a side of giggles."

Example sentence: "The hospital's new 'light therapy' department is so intense, the ghosts started whispering to each other in a language only radiologists can understand. 'Hospitals light particles... and they're trying to lure away the undead.'"
