No, technetium is still a natural product, it just takes a little processing. An organic miner dug up some raw uranium ore, then someone refined it, irradiated it, and isolated the resulting molybdenum-99, and finally a radiologist extracts the all-natural technetium from the decay process of that molybdenum.

Natural = found in nature.

[LeifCarrotson]

It is found in nature, it just has a slightly different number of protons when it's raw.

I know what you mean, but it's just the definition of natural at least on our "earth". If you find some technetium somewhere let me know.

You can argue that, and I might agree with it, but it's not regulated as such.
