Sure. But the question remains, how dangerous? And you can’t go straight from severity of symptoms. You can make someone throw up with a glass of salt water, but we don’t ordinarily consider salt water “dangerous AF”. On the flip side, strontium-90 can produce essentially no symptoms until the cancer starts, and so is more likely to count as “dangerous AF.”
Things like this are why it’s so useful to be able to prosecute for any of poisoning, attempted poisoning, or depraved indifference. Even if what was in the syringe was half and half acetone and Axe.
