"Production and Decay of Strange Particles" is an episode of the original The Outer Limits television show.
In a nuclear research plant, although the workers wear radiation suits, they are taken over by some odd glowing substance.
The episode name echoes a Physical Review paper of 1956, titled "Cloud-Chamber Study of the Production and Decay of Strange Particles.
The truth however, is more terrible, for when one turns to face a colleague who has entered the hot zone to investigate, its faceplate displays naught but television snow...
Just as the ever-expanding particles are about to engulf the lab itself, the head of the research facility in a deux ex machina calculates a formula which reverses the effects of the reaction, incorporates a random element, and neutralizes the subatomic but sentient lifeform that had abruptly gained entry into our world.
