I never take Lead Belly, since I am constantly making large quantities of Purified Water and always carry some with me. I also have the canteen from the Classic preorder pack, which reduces my need to drink in the first place.
I do take Rad Absorption though, since I rarely have much Rad-Away on hand and do not use the Rad Child perk. In fact, I altered how much radiation Cave Fungus removes and increased its availability somewhat so that I could go full-bore Survivalist mode and not be dependent solely on Rad-Away for my radiation reduction needs. In fact, I have some characters that only use the fungus and sell any Rad-Away they find.
Is either one 'needed'? No. Can you make an interesting character concept based on manipulation of internal radiation levels? Absolutely, so if you want to use them, go for it. Heck, with proper use of these and a couple of other perks you can practically play as a Ghoul, if that's your thing.
