I recall when the 64kb DRAMs first appeared and alpha particle hits were
suddenly a critical issue - the doomsayers were claiming DRAM cells couldn't
be shrunk any further.  I suspect moving from CERDIP to plastic packages
and adding suitable coatings to stop alpha particles helped.  In any case,
things have shrunk by about 5 orders of magnitude and no-one mentions alpha
particles any more.
