The leaves and nuts contain the highest amounts of the toxin, I do not believe 50 feet is far enough. Once a plant/tree is impacted, there is nothing you can do to save the plant.
Squirrels are the most effective planters of those nasty walnuts. If you have one on your property you will have many, many, many trees on your property unless you are constantly on top of all the transplants.
Blackberries will survive the toxin.
