Therefore, we have to assume that the
probability of radiation induced cancer or serious
hereditary defects are proportional to the radiation
dose right down to the lowest levels.4,5 This
Linear doseeresponse relationship suggests that
no radiation dose, however low, can be considered
absolutely safe. Although this may be an overestimation
of the true radiation effects, at lowdose
levels, it is preferable to hold to the model
and it is the basis for the radiation-protection
standards of today
