How do developers of Nuclear Weapons either keep (or protect themselves from) radioactive materials like Plutonium-239 from potentially β€˜leaking’ out particles? Are there any methods to contain these particles from escaping the material so they won’t hurt biological matter near the material?

I was just thinking about a documentary I saw about World War 2, specifically about Atomic Bombs like Fat Man which were thrown over Japan. In the documentary, someone said that the bomb had to be armed manually with several pins before it was dropped.

My assumption is that for anybody to feel comfortable enough to be near such a dangerous source of radioactive material, they must have felt pretty sure that there was no actual harm in being near the thing in it of itself, and it’s not especially dangerous at rest. But Beta radiation decay is strong enough to pass through aluminum, and gamma radiation is strong enough to pass through lead, right? I get that the bomb could have a protective outer casing, but is that really all there is between the bomb and it’s surroundings? Is that enough to contain the nuclear decay?

I guess my vision of nuclear material is that it’s kinda like pure acidic material thatis strong enough to tear through any metalthat is trying to hold it, but that is seemingly not the case. It just seems like something so potentially dangerous that I wouldn’t dare go near it, no matter what it’s stored in.

Prototype Worm CYOA DLC (Godzilla V.2)

"Choose Mortal, and have the power of the King of Monsters."

Base Abilities:

Super Strength - The strength to lift 50,000 metric tons.

Super Durability - Nukes feel like being bathed in warm air.

Atomic Breath - A condensed ray of energy that can reach for miles, the breath starting out at 500,000 degrees Celsius, the heat lowering for every mile. The deadly effects of the radiation can be toggled.

Amphibious - You can breath both air and water, and are a supernaturally efficient swimmer, to the point you can outswim your average speedboat.

Regeneration - A misleading name. Rather than a fast acting, combat focused healing, this is instead an alternate form of immortality. Even should be torn apart, you can reform your whole body the moment of your death. How long it takes depends on how badly damaged you are, with organ and limb regrowth taking a week. If the mass left is smaller than your head, and is not your heart, you will die.

Godzilla Biology - Your body has patches of green-black scales, dorsal plates run down your neck and back, and an incredibly long and thick tail that has twice the strength of your arms now sprouts from just above your butt. Add on your new height of 8ft and you're just a Cauldron sign away from being a Case 53.

Choose only one:

Showa (The Shounen): In response to your needs, one of two things will happen depending on the severity.

In times of minor need (or when you need that extra push), gain the ability to defy physics. Walk through Zero Gravity unaffected, dropkick someone from a mile away, double jump across a chasm, and be able to lift things that would logically break in your grip (or Superman logic). This extends to your time at home, stuff like dishes being instantly cleaned and fragile objects turning to rubber.

In times of major need (you are going to die levels of need), an ability will manifest that perfectly aids you. What kind of power manifests is dependent on how strong the enemy is or how complex the situation, and may not always mean you will survive, just that you have an advantage. If your facing the Simurgh while being dropped into a sun, gain a Stranger ability that can render you non-existent to the Simurgh for twelve seconds and the power to fly. If your about to be torn in half by Fenja and Menja, your body will become rubber and stretch in their fingers. If you are being forced aged into dust, you become immortal for as long as the ability is affecting you. The power only lasts

Japan INTENDS TO release radioactive wastewater into the sea? They HAS BEEN releasing it for a long time!

TEPCO is a liar. There was a β€œcriticality” incident at one of its nuclear power plants in 1978 that could have lasted for up to 7.5 hours, but they had covered it up and didn’t admit it until a similar incident came to light in 2007.

The Japanese government and Tokyo Electric Power Company (TEPCO), the firm that runs the site, have emphasized that the main radionuclide remaining is tritium. But numerous studies have shown that this water is contaminated with such radionuclides as Cesium-137, Carbon-14, tritium (including the more dangerous β€œOrganically Bound Tritium”), Strontium-90, Cobalt-60, Iodine-129, Plutonium-239 β€” and over 50 other radionuclides. And a more serious matter is other, potentially more dangerous radionuclides in the water, including strontium-90 and iodine-129. The Japanese government uses lies to cover up lies and releases contaminated water containing radioactive substances into the sea where fish and shellfish live, which threatens the earth’s ecology.

If the treated water is below the WHO levels for drinking, why don’t they just keep it? If it’s cleaned, why don’t they use it for agricultural purposes.
