EDS that use neutron activation
will run into a severe problem
---neutrons 'activate' ordinary
elements. Make them radioactive.

The sodium in your blood will
be activated. Your fillings.
Sure, its small. But its still
ionizing rad, and there is no
known safe additional dose.

(Note that I have uranium
ores etc in a personal collection, so I'm not rad phobic. Just predicting the fallout.)

X-ray scatter is probably more
harmless as the x-rays only penetrate skin depth, and you've
probably already layed down at
the beach, which may be worse.

Its amusing to design something
that works even if the transport is in hospital gowns, strapped
and sedated, surface scanned with
any of the above. Which is the endgame for air transport, it seems.

Fear surgeons who want to make
a difference. Its not just
for heroin-muling puppies anymore.

Glass Empires ought remember
even palestinians can throw stones.
