I'm trying to wrap my mind around how fallout radiation effects flora
and structures/contents.  First, I understand the 7:10 and 7/7/7 rules,
but what I haven't been able to find is just how radioactive is the
fallout.  A lot of examples are used, and that's cool, but that doesn't
help trying to build some reasonable numbers for what the players might
face.

So...in no real order, here are some questions for the following scenario:

The world is relatively similar to Earth in size, composition, gravity,
water percentages, atmosphere percentages, etc; for all intents and
purposes, other than the specific shape and such of land features, it
could be Earth.  The enemy shows up and from orbit thoroughly bombards
it with nuclear weapons (both "enhanced radiation" as well as
thermonuclear weapons - sub/surface/air bursts as the target requires)
striking population, military, government, and key infrastructure
centers.  The attack happens over several hours, no more than six or
eight.  (Essentially, the characters are going to be either on or having
to visit a planet that was attacked in much the same way that BSG showed
Caprica and the other colonies being attacked for visual reference.)

1.  Is the atmospheric disruption and increased particulates in the air
likely to cause increased rainfall?

2.  What is good estimate on the output of the fallout after an hour?

3.  Items that are in a house, say canned goods, dry foods, and meats in
hermetically sealed packets, a danger to the person eating the contents
if the packet has been washed off (decontaminated)?

4.  How much insulating material will be needed to protect someone from
the fallout provided that they are in a shelter that is sealed and has a
way of effectively filtering the air?

Thanks!
