treating uncertainty are to apply statistical methods of
estimation, which are, in turn, based upon
fhe concept
of probability. Even in cases where the source of
uncertainty is of non-statistical nature,
formal
application of statistical methods of analysis is often
made to deal quantitatively with uncertainty, tacitly
accepting the premise that uncertainty - whatever its
nature - can be equated with randomness. Most of the
work on risk analysis or risk assessment has been done
using such methods. In the fuzzy set concept set
uncertainties are accepted as uncertain with the
introduction of the membership function. Instead of the
non-fuzzy two-valued logic ‘true or false’ any
intermediate value between zero
(false)
and one
(true)
can be assumed for the membership function in the fuzzy
set theory. Use of the fuzzy set theory is proposed in
an attempt to analyse the causal relation between dose
and effects under emergency conditions. After the atomic
bombings in Hiroshima and Nagasaki and the Bikini
Accident many efforts have been made to estimate the
dose of survivors.
However,
because of various
uncertainties involved in this type of estimation under
the emergency conditions, the accurate estimation of the
individual dose is very difficult. It was recently
reported that ESR dosimetry could be applied to estimate
the radiation doses of the individual using the enamel
of the teeth of the survivors or material such as
shell-button,
sugar etc.
found on the person.

Bikini Atoll in the Marshall Islands of the South
Pacific was extensively contaminated with radionuclides
deposited by thermonuclear weapons testing in the 1940s
and 1950s. In recent years, the U.S. government has
attempted to restore the habitability of the islands by
cleaning up the remaining radioactive material. Although
the island no longer presents an acute radiation risk to
inhabitants, plants growing on the island concentrate
