Radioactive materials: a reality check

Post by vinni » 06 Nov 2019, 17:39

This post is intended as a informative section on real-life effects of radioactive materials. It is completely BE's decision how much, if any, is to be implemented in-game.

First of all: The important distinction between radiation and contamination.
RADIATION is the direct exposure to radioactive elements.
CONTAMINATION is having radioactive particles on your person, either externally or internally.

HAZMAT suits do nothing against (gamma) radiation. That shit will go through and irradiate you no matter what.
Stand in a high-intensity radiation field long enough and you're dead either way, HAZMAT suit or not.
This is why we follow the ALARA principle (As Low As Reasonably Achievable) to minimise the radiation dose.
This can be achieved through 3 principles:
- Shielding: don't stand in a radiation field or have some heavy mass in between you and the source to decrease exposure
- Distance: radiation drops by the inverse of distance squared, so keep away (at 2m you'll receive a quarter of the dose compared to 1m, at 3m 1/9th, etc)
- Time: if you REALLY have to be in a radiation field, make it quick. dose is cumulative so don't stand faffing about

Why wear a HAZMAT suit, then? I'm glad you asked.
A radioactive source might also be spewing radioactive particles, which we don't want to carry with us, breathe, eat, hold our newborn kids with, ...

So a HAZMAT suit prevents the particles from getting on our skin, in our clothes, the respirator prevents inhalation, etc. Radioactive particles probably won't kill you outright, but the ones that enter your system tend to stay, so enjoy them long-term effects.
This also means HAZMAT suits are single-use (or can't be used until thoroughly decontaminated)


In a situation as presented in the story, we must assume the ENTIRE HAZMAT zone as contaminated. (Why? Because without accurate measurements we just can't be sure and, given an armed conflict, measurements might just not be a top priority for the factions involved)
This does mean that we can't just retrieve items from that zone and consider it safe. Without decontamination (just a fancy way of cleaning it thoroughly, basically) you will only be enlarging the contaminated zone.

You pick up a piece of plutonium, carry it out of the HAZMAT zone, throw it in the car, and deliver it to HQ?
Congratulations, you've contaminated yourself, the car, the HQ, the entire route, etc. Also, good luck with that acute radiation poisoning.

In order to retrieve an item, it must be stowed in a container (preferably shielded, but that depends on how active the component is) and brought to the edge of the zone where a decontamination station must be setup.
Here the box has to be decontaminated, the HAZMAT needs to be decontaminated, and THEN the entire thing can be transported safely.



I am well aware that real-life situations don't necessarily translate to in-game mechanics directly, but this is just an indication of what a more realistic approach might mean.
As stated above, it's up to BE how much they want to emulate this, it's not exactly light stuff and I won't hold it against them if it's a bit much :P


PS: Being shot in a contaminated zone isn't as bad in the short run as if you were shot in a chemical environment as stated in generation kill, but there's a good chance the wound might be contaminated, causing long-term health issues.

very good summary vinni, it depends on how much LARP/ reality BE wants to put in that thematic.

Thank crow we have holy water this year so we get a rebirth :)

Thank you Vinni for this summary. We will deliver more on the mechanics for this game in the OP order given to commanders.

You are ofcourse right, but in the end, it's a matter of making the scenario and effects simple enough so that everyone can relate and understand whats going on.

We can't go up to a level which makes it super realistic, and we dont really want to - But at the same time its not fun if its super simple aswell.
Difficult line to balance.

Idea: Extend the HAZMAT-zone from B17 with the area that the barrels were moved thru to the point where they were decontaminated :?: :idea:

We are not in the same area for Berget 18, we're a bit off but in the same country.
