I was in Hawaii last year when there was the nuclear bomb scare - something like this would have been infinitely helpful (the suggestion by the author to share the page via Twitter/FB etc with other people if they’re about to get hit seems like a good one).

There might be affiliate links on this but I don’t think most people looking for something to save their life would really care :)

I made it and there are no affiliate links on this page.

Affiliate sales page thinly veiled as a PSA.

Agreed. The "main source" link contains pretty much the same info but without the affiliate marketing:

Mate, I made this and I promise you there are no affiliate links and I'm making no money from the site.

I have a real job and don't need an extra $7 a year in kickbacks for selling crank radios.

These SOP's are older stuff, there are very different munitions that have a different demand. In addition to the atomic tall boy, and fatman bombs we need to make different preparations for Neutron flux; nuclear EMP; cobalt salted munitions, and that puts us up to date. in a few years we will have issues with unidirectional discharge munitions, essentially high energy gamma ray lazing devices, and if current directions of research pan out, nuclear isomer munitions of halfnium/actinium may be a concern if they prove to be feasable.

In any event a properly oriented and rivetted trench, and sealed water food supplies are the major necessities.
