I did hear about that. I did not see the info on the tube leak or what might have been released, but I suspect that it was quite low. You certainly wouldn't want to swim in the spent fuel pool, but the water does offer a lot of shielding from direct radiation. There are accidents in every field. The number in the nuclear industry is very low, but things do happen. The media does make even minor things into something major when "nuclear" is mentioned. You wonder how many people are killed/hurt in accidents relating to coal, nat. gas, and other power sources that you just never hear about. It is almost expected that people get hurt (especially in the mines) in these other fields, so it isn't news worthy. It is sad, but it is the way it is.
Radiation scares people because they can't see it. Explosions, mine collapse, fires, etc. in other areas can be seen and people know where the damage radius is. Personally, I would rather get a bit of dose versus getting black lung, stuck in a collapsed mine, etc. Also, burning coal releases more radiation than a nuke plant does (uranium, etc. in the coal). Radiation is everywhere at all times. People just don't see it or feel it, so they don't know it is there.
