though it has nothing to do with the Mongolian people.
[3]Actually, all waves have some of the characteristics of particles and
all particles have some of the characteristics of waves. Usually,
however, the radiation is predominantly one or the other and little
confusion arises under ordinary circumstances in speaking of waves
and particles as though they were separate phenomena.

[9]Nevertheless, it should be pointed out that the precautions taken in
the atomic energy industry are such that absorption of radiation is
not as severe a problem as one might suspect. Fully 95% of those
engaged in this work receive less than 1 rem a year. Only 1% receive
more than 5 rems.
