How is exposure to radiation treated? How does the body react to amounts beyond what is normally safe, and what is that limit?

I know I could be wrong, but I believe its:

radiation changes random atoms in your body, which really fucks with your DNA, increasing risk of cancer and other diseases

acute radiation will turn the water in your body into heavy water and also rapidly produce free radicals which is toxic to cells.

This. But mainly it denatures DNA because of the high energy, that means: No replication of the whole genome -> incomplete genetical info -> non-functional genes -> death.

Mostly what it does is kills cells or kills the DNA and lets the cell live.

In the first case, you straight up just burn/decompose/bleed immediately.

In the second case, you live until cells start dying and need replacement at which point because the DNA is damaged, those cells can't reproduce.

They use agents to remove radioactive compounds from the body. Like Prussian blue.

They give you stuff to prevent thyroid cancer.

They give you the normal stuff, like fluids, blood work to keep your various levels in the green.

Lastly they can give you a drug called neupogen. It will boost the production of white and red blood cells. Assuming your bone marrow isn't totally destroyed. If so only a transplant can help you.

>> No.10739105

The parts of the body that are most affected by radiation are those with a high cell turnover. Organs such as bone marrow and those in the GIT are particularly vulnerable.
Classic symptoms of acute radiation poisoning include nausea, vomiting, dizziness and low blood pressure which can cause people to pass out.
Most people who die of acute radiation poisoning will die of systemic effects like reduced (or absent) white blood cells, making them die of infection. Haemorrhage is also a real danger.

The things you see in the Chernobyl TV shows of people instantly bleeding from their face is bullshit, but at high doses you can get really severe burns which can later turn into bleeding.

For acute radiation poisoning the main focus is to help keep the body alive. So mostly transfusions of red blood cells, saline and maybe immunoglobulin. Later they can also try stem cells and other things to help regrow the parts of the body which are permanently damaged (bone marrow is the main thing you're really worried about).

>people instantly bleeding from their face is bullshit,
I only remember one guy who was bleeding from the face in the reactor building and I'm pretty sure that was from the explosion more than the radiation.

There was also the fireman who touched the graphite and started bleeding quickly but only from his hand
I'm no expert on nuclear physics but I'm pretty sure if you're standing right next to it then just touching for a few seconds isn't going to make such a massive difference

goddamn what a retarded thread. radiation poisoning, if it doesn’t kill you, is basically treated in the same way burns are treated. stay in bed, rest, let yourself heal. it can cause organ failure, especially bone marrow death, so bone marrow transplants and blood transfusions too. if any other organ fails, same deal—transplants or standard treatments. cancer risk is increased but if it is a sublethal dose, usually that is a latent effect and cancer treatment will happen much later once the cancer arises

above a certain amount of exposure, it cannot be treated. Too many cells get their DNA damaged. We cannot repair DNA in cells.

Okay, but you didn't really answer the question.

Strange, but if this false equivalence convinces you, you really don't belong on a Sci board.

Neutrons are not bullets. It is not mass that displaces tissue but energy that destroys the body chemistry that kills.

The easiest way to tell when someone is not capable of having a discussion on something is when you give them an analogy and they totally miss the point of the analogy.
