At 1kt (max for the W54?) most of the effects are under 1 km: eg the radiation radius is only 0.84 km. Looks like if you shoot 1 mile away up wind, take cover from the flash, and then run away upwind you'd be fine with some hearing protection.

Sorry to be a pedant, and I also want to confirm my understanding is correct (yes, I've attempted checking definitions, but.. :)

In this case I think firing the device upwind would be ill-advised, as then the fallout will be blowing back to you.

Edit: thank you for the correction @erikerikson! Noted, and best wishes!

You seem to have reversed the terms.

Being upwind means the wind is blowing away from you towards your target and proceeds past your target further away from you.

Parent is right too, I mixed up one of them. I should have said: shoot toward s downwind and run away towards upwind.

Ah, indeed you did. My brain slipped over that, thank you for helping me see it.
