Anyone read "Calth that was"? im imagining a rad world like that

Could also be a world that has interest to the Mechanicus, who are not normally subject to radiation like people of flesh and blood are (they, their skitarri and their servitors can all be hardened against such things)... but there's a xeno presence they need wiped out and so they send the IG to do it for them.

Maybe a good basis would be krieg, radioactive hell hole that can kill you quickly if not protected.

Now you have me thinking of Mass Effect II. They have a radioactive sun world as one of their levels. A large point of that level was weaving through shadowed areas so you weren't exposed...wonder if you could work that in. Random event where everybody not in shadow (have to designate certain areas of the board, could get kinda finicky) takes a s3 ap- hit or something.

I've been watching Galactica on the box lately and this thread got me thinking about a particular scene/s. It's the one/s where the man and woman (the woman being a silon) are running around a radiated world with no protective clothing or such other than a few injections in their neck. What radiation would this protect you from, or does it only stave off the affects of rad sickness for a time to allow you to remain combat effective?

The idea is that whatever you are being injected with will absorb and neutralize the radiation as it enters your body.

Even if such an injection did exist, it wouldn't be a substitute for actual protection. It would be supplementary.

Certain individuals might be more resistant to the effects than others, just because they're either able to fight on through the intense pain or they have some different metabolic rate which reduces the effects.

Its like how some people can get shot once and die instantly, but others get shot multiple times and survive. Sometimes in the exact same area.

Someone made an argument that marines wouldnt be affected. is that true?

In the same way that being in a tank might protect you from nearly all types of radiation'; assuming the armour is thick enough, and there is some method of filtering the air/water supply. A marine in power armour would be fine as it's a completely enclosed system. Although helmetless-screaming-sergeant-guy would find his face melting after not so long.

They wouldn't be affected in armor. If it's a lower amount of bars that would still be lethal to humans, they could likely come out of it with minimal, if any damage so long as the mucranoid covered them. However, if it's a ridiculous amount of rads like a planet extremely close to its parent star, they'd receive nasty radiation burns across their body and die without medical attention by an apothecary. Going up the scale further, they'd start outright dying with a breach, then to the point that normal power armor could only survive brief exposure, then power armor failing and only terminator armor being strong enough to withstand it, and then it too would fail. It just depends on how intense the radiation is and whether or not the Astartes have mucranoids to protect any exposed skin.

A Marine's body would be more resistant then a normal humans to radiation, even surviving what would otherwise be lethal. But they wouldn't come out unscathed. They might recover from long term damage and avoid cancer and mutation, but we can't say for sure. We don't know exactly what a marine's genetic codes do in reaction to radiation.

You could do a cover save where everyone scrambles for some small portion of shade. Even throwing a corpse on top of you would work.

You have to remember too that most Imperium nuclear weapons and power are fusion powered, meaning they'll likely spurt out gamma radiation if the miniature star is large enough (fusion bombs are pretty much miniature supernovas after all).

Sorry, just have to throw this out there since this is a quasi-scientific topic.

i. No nuclear bomb is like a "supernova". A supernova is caused by an imbalance of a stars gravitational force (inward) and its energy release (outward). When the fusion cuts down to such an amount that gravity overtakes the system, THAT is a supernova.

ii. Most races would easily be able to fight for a short duration owing to a lovely part of ARS (massive overdose of radiation) typically called the "ghost phase". When the entire body has been lethally irradiated, so long as the central nervous system hasn't outright deteriorated, you will function until the next cell turnover. Whereupon, then, you die terribly.

It's like a relay - so long as you don't shoot the guy currently running the course, breaking the legs of the next runner won't stop anything. But as soon as he crosses the finish line (as soon as the cell divides), then you're pretty screwed.


OP: Give us a level of radiation you want and a source and I'm sure we can McGuyver some rules.

On point one, that's the point I was making. IOM largely uses fusion reactors to power their weapons and big bombs, with fusion bombs involving the creation of a small start for a short period of time before its immediate destruction.

Space Marines have an ability to make their skin darken and become anti-radiation/thermal protection.

This particular bit of genetic-reconstructions works overtime in the Salamanders Chapter, which is why all of their skin is jet black.

A naked Space Marine can also be exposed to lethally-high doses of radiation, and will not be particularly bothered by it.

As people have mentioned, high doses are likely to cause vomiting, but anything with immediate effects like that is probably lethal.

I'd fluff up a failing radiation shield that exposes parts of the field causing severe radiation burns: everyone takes a S3 AP6 hit.

Alternatively, if nukes are going off in the distance, or there are serious solar flares, have units take an armor save (shades, helmets, etc) or be blinded for one turn.

Depends on the level of radiation. They for example, cannot survive direct close exposure to any star's radiation for long periods of time, and have their skin burned clean through the mucus layer.

By the time you're close enough to a star for the Ionizing radiation to be an immediate concern; the heat has probably incinerated you already.

Well, yes, there's obviously a logical limit. But a Space Marine can stand naked in an environment that would kill an unaugmented human, was my point. On a battlefield where you are in such fallout that you'll be having cancerous growths inside of a week, a Space Marine isn't bothered. Of course, he might be jet-black for a month or three... but he's not bothered.

Radiation takes a while to kill. Short term exposure, even to really powerful radiation probably would not phase most troops battle ability.

Dosing is also really hard to predict. Lethality of toxin is usually determined by what will kill 50% of the population. Even a very high does of radiation would likely kill MOST people. Others would live on for a long while(and maybe die of cancer many months later).

Space Marines are known to be resistant to raditation. Probably their immune systems are so advanced that they cannot get cancer(otherwise they wouldnt be living for 500+ years). While they might be immune to smaller doses, doses that would eventually kill a normal man, if the radition is strong enough to kill a human in minutes or seconds, it would probably eventually kill a space marine in a few hours.

See, there you go trying to bring real-world science into 40K.

That is the path of madness... and heresy.

Lets assume we are talking about man-made contamination...
Because what has been observed during the chernobyl catastrophe pretty much describes this exact scenario.
Some Liquidators were seemingly untouched by the radiation, while the man working directly beside them died the same day.

You want rules for this? Okay let the premise be that a nuke went off nearby and most of the fall out is, well falling down on the battlefield.

All models are considered to have radiation gear that keeps them safe until they lose a wound or if a vehicle suffers a penetrating hit.

All multiwound models that suffer a wound must make a toughness test at the end of every game turn. If they pass nothing happens. If they fail then they take another wound and suffer minus 1 to all stats to a minimum of 1. The radiation is too intense (vomiting occurs.

Vehicles that take a penetrating hit must roll a D6 at the end of every game turn. On a 3+, nothing occurs. On a 1 or 2 the vehicle loses another hull point as well as suffers a crew shaken result. Open topped vehicles instead suffer crew stunned. They are too worried trying to patch the hole.

One should also note that posions and toxins usually work much faster than radiation.

A small trace of plutonium in your blood will kill you very quickly, not because of the radiation, but it's toxic.
