I turned the radioactive symbol into a textured pencil brush and it somehow turned out really good.
It's the radioactive symbol as a brush. That's about it.
At a small size, it is very crunchy and textured, I usually use it for sketches at a 4-6px size.
At a larger size it becomes smoother. I don't typically draw with brushes that large but it might be useful still.

Feel free to use for whatever, enjoy!
