As i understand it, Krypton's core (according to Jor-El) was made of uranium and became unstable, hence its explosion. By a quirk of science (unexplained in my time of the 60's), it became green kryptonite. Until receintly, it was harmless to us Earthlings; now it emits radiation that can affect us but not as quickly as it does Superman. In any case, lead will still block green k radiation. Thanx.
awesome guys tttt!!
