持续曝露于超过80分贝的声音可能有害。

Continuous exposure to sound above 80 decibels could be harmful.

含有特别具有毒性的钸成分的混合氧化物燃料棒部分曝露。

Mixed oxide (MOX) fuel rods, partly composed of especially toxic plutonium are partially exposed.

那样的话，让燃料棒免受曝露的努力将会面临又一个严峻的挑战。

That would present another serious challenge to keeping the rods from being exposed.
