12 feet of seawater has the same effect as 6 inches of lead.
That is how the NR-1 can getaway with having only the forward half of the reactor shielded with lead.

Just to clarify. The glow associated with Cherenkov radiation seldom occurs further than 4-5 meters from the source. However that 4-5 meter glow of Chernkov radiation can be seen from further than 4-5 meters.
Just wanted to clear up a possible misunderstanding. If anyone on this forum has not seen Cherenkov radiation glows, go take a tour of a nuclear power plant or nuclear lab. I have not seen any picture do any justice to seeing it in person. It is beautiful.
I still remember my first look. It was at Ginna NPP in New York in 1970. It was probably that first look at the glow that started me on my interest in nuclear technology. It was a beautiful thing to see.
