Yes, that's exactly the way I build my setting - my ideas mixed with COTI brainstorming. You will all be credited when I "publish" it for free online eventually.

Oh, talking of my setting, 4 of the 18 subsectors of my map are ready... 14 more to go (I'm using Galactic).

"The purpose was to completely disrupt the supply lines in one, limited raid behind the enemy lines, not kill everything on the planet. Human deathes are "collateral damage", not the mission objective. The matriarchate could use "feet", that is large astroid bombardment, for that purpose, and on a water world they would be even more devastating than nukes."

Oh yeah, rocks hurt, but they take time to organise. A single warship could do either of the nuke raids in an hour or so. My version is blunter - just smash the place and go. Yours is more surgical - targetting needs to be more precise (therefore takes more time), and there's no guarantee you'll be 100% successful unless you're going to hang around and monitor the world.

If you want a few pics of what your world might look like you can go to elenafilatova.com and look at the Ghost Town section. Or if you don't want to leave CotI to do it skip down to Random static, reset your browser to; show all topics and find the "Nice day for a ride to... Chernobyl" thread on page 17.

If the setting has damper tech, you don't need a reactor at all, nor a warhead.

A simple sabotage of a damper box from Lengthen to Shorten mode would result in some pretty effective neutron and other radiations.

Using dampers, you can easily use Cesium dust, or even some of the synthetics... hehehe... and dust it with really hot, really short lived materials. Hit the shelters later with focussed beams set to shorten half-lifes, and away goes the population.

Hope no one minds my stepping into this discussion.

That is both fascinating and troubling. I'll pass on that free ride on the Skate, thank you!

Correct me if I'm wrong, but the ships that became active radiologically, this was as a result of Baker (the underwater shot), and not Able, correct? These bits of info really aid the reality-minded campaigns, and I thank you all for it!

In one of his articles on his web page Andy Slack has a great series of points to made about the use of nuclear & chemical weapons in nice crunchy PDF. Of course, if you are lucky enough to have a complete run of White Dwarf magazines (other than me wanting to contact you...), you will find the original article in there.

After reading this thread, I wonder if anyone had ever read or looked at the DA Pamplet, Effects of Nuclear Weapons. I have a couple of copies, including one with the blast effects circular slide rule in the back. Against that, calculators and spread sheet programs make calculating damage effects using the formulas given in the book a lot easier to do.

The idea of using nuclear weapons to create tsunamis is really the stuff of science fiction. The energy required to generate a tsunami makes even a 20 megaton nuke look like a .22 Long Rifle round. As for scrubbing the island with one, given the mountains in the middle, dream on.

The radiation from a couple of 20 kiloton air bursts in not going to be any form of a long term problem. The bomb at Hiroshima was somewhere between 12.5 to 15 kilotons, while the Nagasaki bomb was about 22 kilotons, using plutonium, which is a much longer headache than the U-235 in the Hiroshima bomb. As for usiing nuclear explosions to drive the radiation plume from the land burst further into the island, no winner there. You do not get any form of sustained wind from a nuclear burst, as the fireball and heated air in the plume with suck air in, not blow it out. The shock wave propagates outward, but the following wind flow is in the opposite direction. The result is opposite pressure patterns on damaged buildings and structures which can increase the damage within the initial burst radius to a degree, depending on building construction. Earthquake-proof structures will survive much better than standard construction.

With respect ot half-life of isotopes, ten half lives reduce the radiation by 1000, 20 half lives reduce it by 1,000,000. So a 5 year half life isotope would have decayed to 1/1,000,000th of activity after 100 years. The most likely source of long-term radiation from a nuclear burst is Cesium-137 and Strontium-90. For anything else, you would have to manufacture that in a nuclear facility. To contaminate the entire large island adequately is going to take a lot of material, and then you still have to deal with your contaminant in the environment. it is not going to stay in one spot, but is going to keep moving. If highly radioactive, then there is likely going to be a fairly short half life. Remember the 10-20 rule, after ten, activity drops 1000, after twenty, activity drops 1,000,000.

One other factor that no one seems to have considered is how reliable are the nuclear weapons used? How long have they been in the stockpile?

If anyone is interested in chemical weapons, a good starting point is the U.S. Army's history of World War 2 series, specifically, the Chemical Warfare Service histories, starting with From Laboratory to Field. Every chemical mentioned in that book is in common use today in the chemical industries. A current Phosgene plant will likely produce 10.000 tons per year, as it is used in the making of PVC plastic, and a chemical engineering manual has a detailed plan on how to make a plant. It should be noted that for purposes in World War 2, a U.S. production of 700 tons per month, 8400 per year was viewed as adequate. There is a lot of chemical warfare material online from World War One, including how to set up a Chemical Warfare Service.

One more comment, a plant sufficient to produce a ton of VX nerve agent a day could be built in a building the size of a 2 to 3 car garage. VX is a liquid resembling light motor oil, for contamination of an area for up to 2 weeks.

Pleasnt Dreams everyone.

And since the original post, we have had a tsunami-induced nuclear plant explosion in Japan, to provide another set of data for study and adaptation to the game purposes. This one came pretty close to the 'chain reaction disaster' OP was trying to craft.
