About 100 times as bright as the sun's visible radiation, but it only lasts for a few hours at most, and dissipates in the upper atmosphere.

Still, human life on the side facing the blast would be gone, wouldn't it?

No, not if it was 10 light years away. The radiation would not reach the ground, and the heat might not propagate to the surface either. It would be more easily noticed at night if there were no clouds.

The quote from the article claimed there would be mass extinction due to the ozone layer being damaged, but that is not really possible. The ozone layer is caused by UV (sunlight) disassociating oxygen molecules in the upper atmosphere.

If you still have sunlight and oxygen, you will have ozone.
