Uhh… not quite.
The radiation level on the surface of the “Elephant’s foot” is around 10,000 roentgens per hour, which is a lot (an exposure of 500 roentgens in five hours is a lethal dose).
However, simply looking at it would not instantly kill you you would have enough time to take a few steps toward it and admire the glass formation before collapsing.
A quick peek around the corner and a direct glance would give you only around 2-5% of a deadly dose. In fact, you could view it with your own eyes through a mirror perfectly safe(-ish), as only visible light would be refected.
