ICRP developed the concept of “acceptable risk."
Unless man
wishes to dispense with activities involving exposures to ionizing
radiation, he must recognize that there is a degree of risk and
limit the radiation dose toa level at which the assumed risk is

For planning purposes, dose limits for
members of the public are set a factor of ten below those for
radiation workers.
The dose limits for members of the public are
a somewhat theoretical concept intended for planning purposes.
It
will seldom be possible to ensure that no single individual exceeds
this dose limit.
Even when individual exposures are sufficiently
low so that the risk to the individual is acceptably small, the sum
