True. I don't know what kinds of properties would make lead stand out from other solids, though...
That it blocks the effects of PLUT and URAN and, POLO.
BRILLIANT
Lead blocks the effects from PLUT and URAN and, POLO also DEUT. It also shields everything from Radiation or Radon. The gas is produced from decayed URAN, this could be produced from all the radioactive elements. I had an element idea but not sure if I'd post it. About a semiconductor that turns into NBLE. Lead absorbs radiation and produces OXYG.
