Oh boy, it's another science-related simulator. I'm getting deja vu... m mutes the gray counter's pinging cuz it's annoying
OF NOTE: U-243 does exist. it has a half life of ~16 minutes the U-243 atoms in the simulation have an average ~5.19 second half-life. Its "depleted" form also decays into lead. Simulated U-239 atoms have a half life of about 18.29 seconds Actual U-239 atoms have a ~23 minute half life.
