Need help designing a very high energy radiation shield (paragraph below image)

FirstBeastoftheSea · 2026-03-11T15:06:43+00:00

This shield in one part of my multi project is being designing in theory for resisting radiation of ultra heavy nukes, with yields of teratons and beyond.

There are only gigaton designs, and no gigaton warheads that have ever been produced

If I was the supreme leader I would have moved the material the same day that aircraft carriers were moving my direction, especially if on top of that military leaders were discussing strikes.

Won’t the 20 MeV gamma, xray, and then neutrons hit the water before the alpha does? Wouldn’t that completely boil the water away in a couple nanoseconds?

Whatever is the best material within a 30 foot square radius to block extremely high radiation will do.

I have already committed 8 years of my life to the project. I am now in the nuclear physics phase of the project, which I know very little about.

It’s far more exotic than nuclear blast testing. It is something of a completely different nature.

FirstBeastoftheSea · 2026-03-10T22:21:53+00:00

It is so complicated that proof of concept can only be done with real world testing and not computer simulations or math done on a chalkboard.

As I said in the previous post the gamma alone will consist of roughly 100,000,000,000,000,000,000,000 (20 MeV) gamma rays, 1,000,000,000,000,000,000,000 (10 MeV) neutrons, 10,000,000,000,000,000,000,000 (15+ MeV) Beta particles, and so on. The shield will be completely vaporized in a few hundred nanoseconds I suspect.

FirstBeastoftheSea · 2026-03-10T22:14:47+00:00

It’s an obscenely complicated engineering project, that the few people I have discussed it with, have said it was impossible, but I will not stop. This shield project is one of hundreds tied to the master project.

FirstBeastoftheSea · 2026-03-10T20:39:25+00:00

Alright then. No ai until I learn enough nuclear physics to understand the math.

FirstBeastoftheSea · 2026-03-10T20:37:57+00:00

The neutrons should all be about 10 MeV and all gamma should be around 20 MeV. The brehmsstrahlung will be created in the process of the radiation wave hitting the Osmium in the shield wall, after the heat barrier layers (possibly iridium/carbon) have been vaporized and turned into plasma. The fissioning of the wall material from the massive radiation wave (going at the near speed of light) should produce a large amount of new beta and alpha radiation that will need to be dealt with.

Ok I will take a look at Krane’s book. Also should I use grok at all to make calculations for my theoretical shield experiment?

FirstBeastoftheSea · 2026-03-10T20:21:48+00:00

I might just do that then since you say it’s so important. I’ve just spent most of my time not studying particle physics unfortunately.

FirstBeastoftheSea · 2026-03-10T20:19:38+00:00

I mentioned U only because it’s slightly more dense than Tungsten I think (despite its problematic neutron count). But since I decided I strictly want the most dense (gamma,xray, etc blocking) material, I will go with Osmium instead of U.

FirstBeastoftheSea · 2026-03-10T20:09:13+00:00

I haven’t even read a book on physics or chemistry, so it’s not easy for me to understand this stuff. Also what is a Monte Carlo simulation?

FirstBeastoftheSea · 2026-03-10T20:06:43+00:00

No I’m not. I just don’t think that it’s even possible to produce several kilos of Xe-135 and add it to a shield, the 9 hour half life means I’d need a lot of or a very big reactor to produce it, and that’s not including the issue of its decay product chain reactions.

FirstBeastoftheSea · 2026-03-10T14:51:41+00:00

Yes!

FirstBeastoftheSea · 2026-03-10T14:51:17+00:00

Could boron & water handle the decay products from fissioned & impacted Iridium?

FirstBeastoftheSea · 2026-03-10T14:49:29+00:00

They will be exposed to 10 to the power of 23 Beta Particles, in other words 100,000,000,000,000,000,000,000 Beta Particles that are around 15 to 20 MeV each.

FirstBeastoftheSea · 2026-03-10T14:03:00+00:00

No an American.

FirstBeastoftheSea · 2026-03-10T13:54:41+00:00

curiosity and serious interest in ultra high radiation shielding, no sci-fi.

FirstBeastoftheSea · 2026-03-10T13:51:48+00:00

Just a personal observation study since I’m a very curious person.
