If you are the 'Queasy' type, maybe you shouldn't read this post, just skip over it.
Some of this is pretty hard to deal with and it's better NOT to have this stuck in your head...
I'm a former military NBC (Nuclear, Chemical, Biological) training officer.
The dangers in radiation aren't what you think...
Once EXPOSED, there isn't much that will save you.
You will need to be taking doses of KI PROPHYLACTICALLY
to keep the damage to a minimum in the initial exposure.
Since KI is a Iodine, you CAN NOT
take it Prophylactically or it will kill
IF KI IS NOT IN YOUR SYSTEM
when you get exposed, there isn't much that will help you...
KI is for people in the general area, or down wind, or workers that will have to work in or clean up the mess afterwards,
that will be exposed, but didn't get in the direct blast area, or didn't ingest any of the radioactive particles.
FILTERS ARE YOUR BEST LINE OF DEFENSE!
KI will just help you resist the background radiation from light fallout on the ground... WHILE YOU HAVE YOUR GAS MASK ON!
How radiation effects your body...
Smaller doses will damage the nucleus of the cells, and it can't reproduce, or it reproduces in a way that doesn't serve it's primary function,
So you die very slowly, usually of infection since bone marrow can't reproduce blood cells, white or red.
Slightly larger doses, or ingested doses in food or drink will kill off the bacteria in your gut, so you can't break down food for digestion.
You will slowly starve to death if the intestine doesn't rupture and cause a massive infection that kills you.
Most of the damage will be to cellular DNA, the radiation simply damages the cells until they are no longer able to repair themselves when bacteria or other infections attack.
Slightly larger exposure and you will find the cellular membranes starting to break down, the cellular material will simply liquefy and become acidic or infected.
No replacment/replication of mitochondria content, no feeding the cell or getting rid of it's waste products, and it dies, but it literally starves to death.
As the effected cells rupture, their waste product will cause massive infections in the surrounding healthy tissue (if there is any) so the infection MUST be treated or drained...
Yup, that means popping those blisters and letting the pus drain out, but keep them CLEAN,
you don't have an immune system at this point, so you should be hyper vigilant of infection sources.
If you survive the dose, you WILL
be permanently damaged.
Dermis layers ('Skin') scars will be the least of your worries...
Organs that process contaminants will be the primary concern, since they are getting the largest doses.
Liver, kidneys, intestines will all suffer the worst.
Even relatively small does can cause cancers later in life by damaging the DNA in the cells.
Simply destroying the protine string that turns 'OFF' the cell's reproduction will eventually cause cancer...
Clusters of these cells that aren't aggressive are called 'Benign Tumors', they just don't know quite what they are supposed to be doing, and can't stop reproducing...
So you wind up with 'Tumors' made of these cells that are malfunctioning, but can't stop reproducing.
Run away cell growth will eventually produce a 'Cancerous' variation of it's self, it's inevatible.
Sooner or later there WILL be a 'Malignant' vairation show up...
If it has runaway reproduction, we call that 'Malignant' or 'Cancer'.
Most radiation cancers & growths are in places that get direct exposure to the radiation,
The lungs, digestive tracts, kidneys, liver from direct contact with radioactive particles inhaled, drank, or eaten and since these organs have the least resistance to radiation.
(other than your thyroid, which is of little concern at this point)
Skin is always vulnerable since it's your first line of defense.
Even 'Benign' tumors should be removed when found since they contain the 'Always On' gene and can later produce that one mutant cell that starts a malignant tumor!
Some preventatives you might not have thought of,
Any milk with the fat content still in it, but Cows milk in particular, will help remove particles from your digestive tract, liver and will help remove the heavy meal buildup that will happen after a human is exposed, particularly to Gamma radiation.
Gator Aid or other mineral & electrolyte replacing drinks will help you flush the kidneys and urinary tract without inducing water intoxication or salt/potassium depletion.
