NOTES FOR MOBILE VERSION:
Optimized for a 320 x 480 screen, as that's what the G1 has, and I have one.
r is used as shorthand for radius.
is used as shorthand for "degree"; as in 1 Burn = '1st Degree Burn'.

All figures assume optimum burst height for device; and the HOB for no local fallout is merely an approximation which can be off by as much as 30%; and while there may be local fallout; it will be at levels acceptable under emergency conditions.

Programmed by Ryan Crierie, based off a nuclear weapons calculator by Michael Wong, with special thanks to Michael Wilson for helping me with the value increment buttons for the mobile version.
