I don't think that is the case. The kinetic energy of these super-energetic particles is often compared to a tennis ball. But that energy isn't released at once, so even if it would interact with yourself, that interaction creates a particle shower that takes most of the energy with it. I don't think we can feel one of our atoms getting violently ripped apart.
There’s Anatoli Bugorski [1] who accidentally put his head into the path of a high energy proton beam.
The injury resembled nothing like being hit by tennis balls.
> He reportedly saw a flash "brighter than a thousand suns" but did not feel any pain.
He’s still alive today, age 83.
