1 For a definition of millisievert, see the list of symbols and definitions.
2 Frequent fliers who travel for more than 1,200 hours per year
could receive doses of up to 5 mSv.
3 Range in individual doses exceeded for only 1 per cent of patients receiving
diagnostic radiology,and some patients receive up to a few tens of millisieverts.
4 Average annual dose some 90 per cent from natural radiation.
5 The range figure for individual doses is an average in high deposition areas,
mainly from Chernobyl, but some individuals might receive more than this.
6 Average annual dose some 25 per cent from natural radioactivity.
In 2000, maximum individual doses were less than half the annual limit for the
public of 1mSv.
