low-energy electrons in great abundance. Studies with water, a main constituent
of living systems, can be partially checked by radiochemical measurements. They
shed considerable light on the physical and chemical changes induced by radiation
that must ultimately lead to biological effects. The subsequent chemical evolution
that follows energy deposition within the tracks of charged particles in water is
described in Chapter 13.
