Then you'll need to get it checked before you go making decisions about it. (8+)

The way Curie detected radiation was by holding radium very close to her eye in a dim room. When the alpha particles hit your retina, you see a little flash or "scintillation".

Then she died of cancer.

Alpha particles wouldn't penetrate past the cornea. They only really become a problem when ingested, such as that Russian bloke and the Polonium 210.

If one is diving so close to the limits that +/- 1% will make a difference then the error has already been made.

In fairness, you're not wrong. Just a truncated version of her life. :lol:
