Can radiation be felt? If I pick up a tube containing radioactive material, would I feel the radiation coming off it in any way, or would it feel just like a regular metal tube?

Supposedly astronauts in orbit occasionally see blue flashes from the Cherenkov radiation emitted by high energy particles crossing through their eyeballs (https://www.nature.com/articles/228260a0), basically, the speed of light in water/the inside of an eyeball is about 2/3rds of the speed of light in air or a vacuum. So high energy particles can actually travel faster than the speed of light in an eyeball. That causes the blue glow we associate with the inside of a nuclear reactor
