There are a few ppl who use cheap "tin horns" or culverts to
make a budget shelter.
The fact that it is metal would likely help a great deal with EMP
and it needs 3 feet of earthen equivalent mass around it.
Round tubes do better with pressure, than square boxes.
Another man has shown how to make a short term one with
just a shovel and a folding saw from the wilderness.
There is more than one way listed.
The longest you should have to stay underground is 2 - 3 weeks,
unless in an area that was saturation nuked.
You can get an old civil defense meter with a booklet on how to
operate it and calibrate it off Ebay, or you can make your own
makeshift kearny meter, some ppl even sell them as kits.
After that there are particles out there that can get in the food,
but they have a half life of 27 years or more.
Standard fallout meters will not pick up some of the trace amounts
of these isotopes and it will require something beyond a CDV-777.
The water issue can be dealt with via a solar still, nuclear winter
could last for years and all animal life will likely be dead if it is a
large scale attack.
The still will likely accumulate radioactivity over time, some materials
do not accumulate as much.
Plants can pull up radioactive particles into them, so it will take great
care to make it after a large scale event.
Chernobyl showed the radioactive plants as an example.
