Can't I try dodge? Grenades don't have a high blast rating, and I got 3 agility bonus.

Eh. I am unsure as to specific rulings here, but given the massive area in which shrapnel covers, I don't really see a way you can dodge through it... It'd be like trying to dodge through a gas, it doesn't really work. Besides, it's only light damage.
