NASA | Radiation Shielding Materials Containing Hydrogen, Boron, and Nitrogen

Great Scientists, future of humanity!

[@americannomadnewsthecardbo4339]

Thank you for your work.

[@FingersBlazin]

This technology should be used with active shielding that uses gossamer structures. Active shielding is way better but if you loose power, you are in trouble.

[@TheDrakanMaster124]

Are you been doing my own research on magnetic plasma shielding and it's like the closest thing I'll ever get to Like a sci fi force field But it should be able to block radiation pretty well especially if you feel that area with something like ozone

[@mambiwhoknows2501]

This is incredible. I would like to know more about the current research in radiation shielding materials.

[@Joe-jv5mm]

Just go to your local 🇨🇳🇷🇺 embassy and fill in the Paper Work, important that you include your Spy training, handlers and Code word's, Fax the above to Langley Virginia 🇺🇸

[@mambiwhoknows2501]

@@Joe-jv5mm will do! Thanks for the advice. Hopefully gonna have these papers ready by the end of the week.

[@marcopohl4875]

does the hydrogen have to be in a specific state or would any do?

I didn't expect to read such an elaborate and highly founded intelligent criticism here, but hey waddayaknow right.

What kind of shielding effects can deuterium provide? I know they use it concentrate neutrons in reactors. Neutrons have a harder time passing through.

[@mackcullison6316]

Deuterium doesn’t absorb neutrons very well. In fact, deuterium is used as a moderator for CANDU (Canadian Depleted Uranium) reactors because it has such a low cross section. Moderated neutrons are more dangerous because they will readily absorb into material making them become radioactive. This is great for nuclear reactors, but not human bodies unfortunately.

[@SciHeartJourney]

@@mackcullison6316 Thank you for enlightening us (me)! Yes, I'm aware of what a moderator is, but I didn't realize slowing down neutrons made them MORE dangerous. 🤔 I shared my idea, exposing my ignorance. Now I'm going put that idea to rest. I follow "science", not my own silly notions. I ask questions, sometimes I don't like the answers, but that's life.

[@SciHeartJourney]

@@mackcullison6316 Thanks for that answer. So a secondary idea I had was to use my "deuterymer" (polymer made with deuterium): Portable, miniature nuclear reactor. It's easier to carry around a plastic than a bottle of water. Again, exposing more of my ignorance! I'm just an "engineer", not a "scientist". I like to "tinker" with things, theoretically at first. 😀

[@mackcullison6316]

@@SciHeartJourney Moderating neutrons so they can be absorbed by something like boron is a shielding strategy. Deuterium plastic. Let’s discuss this for a second. We need a critical mass to be a reactor. It wouldn’t fit in your pocket. Critical mass is achieved by compressing fissile material into a small volume. Pu239 has roughly a 4 in diameter sphere. However, this does bring up some interesting points! Hydrogen is more effective at slowing down neutrons, ie, neutrons stop a lot quicker. There is an idea of hydrogen density that comes into play. Water has a really high hydrogen density, paraffin wax has a bit better. The second point I want to bring up is making a reactor smaller can be achieved with other methods, in particular, neutron reflectors! In a nuclear reactor this is accomplished using baffles, or down comers, which is basically a blanket of water surrounding the core which is pumped in from the bottom into the core to cool it off. I’ve had an idea or two on how to make a very small reactor. It takes advantage of temperature coefficients, the warmer reactor fuel and moderator is, the less reactive a reactor becomes. The opposite is true too. Cooling of moderator, below room temperature, can make a subcritical reactor critical. This paired with a reflector of good albedo, and a small neutron source (PoBe) could be a really effective small reactor! Simply deuterium in a plastic won’t produce any energy as deuterium isn’t very radioactive. If you wanted to pursue a waterbottle of energy I would recommend a tritium water bottle with a scintillating material. This is basically how green fire exit signs in buildings make their continuous light

@@mackcullison6316 😄 thank you for that wealth of information. By "portable" I meant something that could fit under car's hood, not in our pockets. You're reminding me of The Six Million Dollar Man; the most incredible thing about him is the atomic battery for his bionics. I've been looking for my own since 1974 😆

Obrigado

I would so enjoy talking to her

Heat does flow in vacuum or not? Please give me the answer it's important

[@mikethespike056]

Radiation can travel through a vacuum and radiation can heat things. So... yes, you could say it does.

[@DreamDropsTV]

The sunlight what it is? A radiation only don't u feel the heat in earth?? It travels so many kms in the vaccum space

[@saucersource]

Do we have any published details of captured space radiation. Not the dosage recordings from the astronauts but what is going on out there. As figured by Tesla what was going on out in outer space was coming in here and thus determined we needed a jacket 36" of lead protection that the Earth provided. You remember, Mr Comic Ray himself.

[@mikethespike056]

This was 8 years ago... What happened?

[@soorajmannancheri974]

My objective is installation of 2*10^(46) watt solar panel

[@yoskarokuto3553]

how you block all cosmic-ray , gamma-ray , x-ray and many high energy particle with only 0.1 mm aluminum fiber shield use in 60s' apollo space suit for 8 day mission in space ??? 🤣
