So... the encounter states:
The characters approach a huge crater from a nuclear strike, once aimed at a large mechanized force gathered here. The crater is 6D6 (I rolled for 18 = 180m) hexes wide and twice that many meters deep. There is a small lake of greenish water in the bottom of it. The entire visible crater, as well as an area twice as wide around it, is still radioactive. Moving through this area inflicts 1 rad every stretch. In all of this area, there are dozens of rusting wrecks of armored vehicles. These are destroyed beyond repair, but D6 of them can be scavenged for parts. Note that the PCs will likely be severely affected by radiation if they stay to scavenge the vehicles. The road is destroyed here. To pass around the crater, a vehicle needs to go off-road and lose one hex of movement this shift (modified by terrain) before movement can continue.
Scavenging a single vehicle takes a Shift, which would mean the players would get a ridiculous amount of radiation, something in excess of 30 rads (6 per hour and a shift is 5-10 hours). How am I supposed to run this encounter without turning my players into walking mutated glowsticks? Will that radiation kill them outright or just give them max rads?
