Ammonia Smell correlates to NH3 quality?

[18294]

SWIM was wondering if true refrigerant grade NH3 has a more powerful smell than Nh3 made by mister clean or krackleback's method.

Someone a while back wrote about RG, so I was wondering... let's say you had a liter of RG NH3 and you drained it outta your tank and let it sit in an unrefrigerated coffee can, or something of that size. You run away to avoid the smell. How far away would you be able to smell it from? 1 acre? 2 acres? 1/4 mile?
