Money, money, money… must be funny… in a nuclear physics world!

You know the main difference between chemistry and nuclear physics? It’s that nuclear reactions are about a hundred thousand times more powerful than any dull, grey chemical hydrate could ever dream to be. And while medieval alchemists were busy boiling rat urine to make gold, nuclear physicists scribbled down the formula for beta decay: n → p + e⁻ + v⁻ Here’s the gist: n is a neutron that used to mind its own business, and p is what it becomes after experiencing the spiritual awakening of beta decay. Sounds insane? But from a nuclear point of view, you can technically turn oxygen into nitrogen, arsenic into germanium — even mercury into gold. And that’s where we stop… and start nuclear-financing some money. If you can turn mercury into gold, why isn’t anyone doing it? I mean, imagine the business! Actually — they already tried. Back in 1941, at the University of California, scientists did make gold from mercury. There’s just one tiny problem: the experiment cost around a hundred thousand dollars… and produced a few atoms of gold. Do the math — that’s about $100,000,000,000 per gram. Not exactly cost-efficient. You’d think it’s simple — just zap some mercury with beta radiation and enjoy your golden life, right? Well… not quite. First of all, you can pour regular mercury right back into your thermometer. To make gold, you need an unstable isotope — because stable ones don’t decay. So, you have to knock mercury out of its nuclear balance, make it radioactive, and for that, you’ll need to bombard it with neutrons. Once you get Mercury-196, you can move on to phase two. Now we need a positive beta decay — because that reduces the number of protons in the nucleus(For the record, negative beta decay does the opposite, it adds protons.) At this point, you’ll want to grab a calculator — because to “zap” mercury-196 with a positive beta decay, you’ll have to load it into a particle accelerator. A particle accelerator — or more precisely, a cyclotron. It’s a glorious metal booth where particles spin in a spiral, pushed by a magnetic field, gaining speed and energy until — bam! — the scientists unleash the beta beam and fire. Sounds epic? In practice, it’s bureaucratic hell — and getting a license to use a cyclotron for “alchemy purposes” is a whole new level of boring. And then there’s the power bill. Cyclotrons eat electricity like monsters. You’re looking at hundreds, maybe thousands of kilowatts. Add the beam energy on top — and voilà, your one gram of gold now costs a hundred billion dollars. Oh, and by the way — the gold you get is radioactive for a few hours, maybe a day. Not all mercury atoms transform; some remain stubbornly moral. The result? A glowing, unstable, gold-mercury hybrid worth as much as a galaxy — and just as impractical. As the band Tsvyakhy once sang in their song “Alchemy”: I proclaim to the world: LONG LIVE NUCLEAR POWER!

What Would Happen If You Fell Into a Nuclear Reactor?

Let’s imagine a scenario where it somehow happens. Maybe our unfortunate volunteer is a maintenance worker — a welder. So, picture this: our welder’s been sent to tighten a few bolts near the top of the reactor. He’s muttering to himself about why they didn’t install a lift — climbing twelve or thirteen meters in full gear isn’t exactly a joyride. Up there it’s hot, humid, and covered in steam. He slips… and down he goes. Straight into the reactor core. Now — what happens next depends on what kind of reactor we’re talking about. But before we get into that, let’s quickly cover what a reactor actually is. Imagine a giant metal pot full of water. That water gets superheated by nuclear fuel rods. The “steam” goes off to drive turbines and make electricity. The “spices” floating around — those are radioactive particles having a rave. There are two main types: • Boiling Water Reactor (BWR) — where the water literally boils inside the core. • Pressurized Water Reactor (PWR) — where it doesn’t boil, because it’s under insanely high pressure. Spoiler alert: you die in both. Scenario 1: The Boiling Reactor If you fall into a boiling water reactor, you’ll basically be cooked alive in seconds. The water temperature is about 300°C (572°F) — not exactly spa conditions. And that’s before we even mention the radiation, which is off the charts. Your body would start breaking down at the molecular level almost instantly — think less “human” and more “radioactive soup.” You’d release steam (since humans are mostly water), plus gases like carbon dioxide, methane, ammonia, and hydrogen sulfide. And because your body is now messing with the neutron balance inside the core, you’d actually cause a brief spike in radiation levels. Scenario 2: The Pressurized Reactor Good news — here, the water doesn’t boil. Bad news — it’s still around 320°C (608°F), but it stays liquid because the pressure is around 16 megapascals — about 160 times the pressure of Earth’s atmosphere. So before you even get the chance to cook, you’d be crushed flat by the pressure. Even if, by some miracle, you managed to grab onto something and not sink — nobody’s going to save you. They will only ask you to fall and accept your death. The Bigger Problem A person falling into a reactor isn’t just tragic — it’s a nightmare for the whole power plant. Within minutes, sensors would go crazy, alarms would blare, and neutron activity in the core would spike. The operators would have to shut everything down immediately. Then comes the cleanup: draining and filtering 200 to 400 cubic meters of water, removing radioactive debris, recalculating power loads, writing reports, dealing with the media… Basically, it would be three days of chaos and a career-ending headache for everyone involved. The Moral of the Story: Don’t. Fall. Into. The. Reactor. Read more
