Surviving the nuclear exchange
Posted: Sun Aug 30, 2009 3:10 am
I was, oddly enough, a trainee member of the UK's Civil Defence Corps. It had an underground emergency communications floor on Regent Street where I put in an evening a week learning how the people of Britain might survive a nuclear attack.
Time's gone full circle. What was relevant back then is becoming relevant again.
Any international airport, power station, container port, military base or centre of local government is a potential nuclear target. If you live within, say, fifteen miles of one, could your family survive such an attack? Death as a direct result of a nuclear blast beyond fifteen miles would be a rarity, death indirectly as a result of civil breakdown is beyond the scope of what I'm discussing. Rescue after a single nuclear explosion would be a rapid national coordinated response, rescue after a nuclear exchange involving many such explosions would be arbitrary and piecemeal and that's the situation I'm addressing here.
How do you know you're down to the wire and entering survival mode? The horizon silently lights up as though the sun switched on. Nothing else can do that, it's a nuclear attack and it's more than a mile away or you'd not even notice it had happened, you'd be beyond caring.
You've remembered the right response, you've not looked toward it, you've dived immediately behind a solid barrier and stayed down until the sudden light's faded. At this point you're not a casualty, you're a survivor. The trick is to stay that way for the next month. A month from now there'll be practically no area left sufficiently radioactive to kill you (though plenty capable of shortening your remaining lifespan). Within an hour you might be enveloped in a radioactive hotspot which is lethal. That's the luck of the prevailing wind mostly. If it's a single blast nationally you'll be rescued anyway. If it's one of many blasts there's no direction to run which is predictably safe, what you need is shelter. If you're not prepared and this is a genuine nuclear exchange and the wind's unfavorable then I don't think you'll live.
Raiding the local supermarket at this point is a bad idea. Lots of other desperate people will be doing the same, it'll take too long (the potentially lethal radiation's about to arrive in an hour or so) and you have important matters to attend to. If you've not made preparations in advance then you're not in control of your fate. If you can't get to your shelter in the next few minutes you're already a victim.
Every house within the fifteen mile radius which hasn't collapsed will by now be burning to some degree or other, including yours. Your first priority is to get home and put that fire out, your house is your prepared shelter. To quote from the Civil Defence Act 1948, “a shelter” means any premises, structure or excavation used or intended to be used to provide shelter from any form of hostile attack by a foreign power. Take it from me, nobody else has prepared one for you. If you've not got your house ready beforehand you're not going to be able to live there until the emergency's over.
The sudden light's faded, there's a physical shock wave coming. Get into the open and ride it out unless you're already in your house. If you're already in your house stay there so you can put the flames out, if it collapses you've got no shelter anyway and you've already lost. Hide behind furniture from the inevitable flying window glass until the shock wave's past. Once it's over go from room to room extinguishing all flames. The place is going to be open to the elements from now on but you've prepared it as a shelter so you're on track. Your family has standing orders to all get home as soon as possible, your job is to have the place ready for them assuming they can make it. Don't go out searching for them, they have to come to you.
Your objective for the next month is for your family to avoid exposure to so much radiation that they'll die of it within the next year. That involves staying inside a part of your house from which you exclude as much radiation as possible. Initially you'll have to stay inside practically all the time. As the outside radiation level drops you'll be able to spend more and more time out of your shelter. After a month the outdoors will be relatively safe again.
As large as possible an area of the lowest floor of the house is your shelter. It needs to avoid proximity to an outside wall, it needs to avoid any breeze carrying dust from outside to inside.
Once the fires are permanently out, switch off all the utilities mains - water, gas and electricity. They'll be dead soon but you don't want them leaking. Then staple prepared ply shutters to all the external window frames around your shelter area. Staple prepared polythene groundsheets to the floor immediately above the shelter area because that space above is going to accumulate rainwater and you don't want rain penetration to drip in contaminants. Staple prepared polythene groundsheets across any stairwells to isolate the shelter area from the rest of the house. That's the breezes dealt with. It's going to get smelly in that shelter space but it's not going to glow in the dark.
Within the shelter space you've previously placed enough dry-goods to feed the residents for at least a month. Be very careful with your choices, it all has to reconstitute with cold water, there's no fuel to cook with. A half ton of instant potato powder is useful, the same weight of rice or pasta will just be a lethal frustration. You've also placed enough 1-ton filled water butts (they're reinforced 3-foot 224 gallon cubic plastic containers with taps) to provide at least a gallon per head per day.
An hour or so after the explosion, radiation will rapidly build up outside. If you're in a hotspot then anyone still out there is at risk. If you're not in a hotspot you're extremely fortunate. If you bought a Geiger counter you can tell. What you can't do is know whether wind shifts will change the radiation levels outside. Stay put where you're safer.
Do you let people into the shelter space after the first hour? Of course you do. Get them to strip and soap-wash top to toe before they come through the outer door. If you managed to set up an external double door with those polythene groundsheets then between the doors is a good place for the decontamination.
The radiation outside will peak within the first day (though more may arrive as fresh explosions and wind changes dictate). It will halve in strength every three days thereafter. That's a drop to a tenth of the peak after ten days, a hundredth after twenty, a thousandth after thirty. One hour's exposure during the first three days is as dangerous as two hours in the next three days, as four hours in the three days after that and so on. Staying away from the radiation becomes less necessary as time goes on but those first few days, if you're in a hotspot, can be lethal. By the end of the first month the lethality is, to all intents and purposes, gone. So long as you avoid bringing significant quantities of radioactive dust in during the early days the shelter will be your protection. Ingesting it is your greatest danger, that's why you're keeping it out as much as possible.
Other bits you might find useful include spare clothes, disinfectant and wipes, several wind-up torches and radios, sleeping bags to stay warm in, a large septic tank and a first aid kit. You don't have enough water to flush toilets, they'll be inoperable. Get the septic tank or you'll be completely adrift in days.
What you'll find after you walk out I've no idea. The trick is to get through that first month without killing yourselves.
