| 内容简介: |
The biological models for radiation and many chemicals have been seen as
having
substantial differences. Radiation has no lowest exposure at which
adverse health effects result and the dose–response curve has been assumed to
be linear from levels at which it can be measured to the no-exposure level—
lower doses are less likely to cause adverse health effects, but they are never
nonexistent. In contrast, at least some chemical exposures have been assumed to
have threshold effects for individuals, exposure levels below which for a chemical
taken in isolation no adverse health effects occur. Thus, although there can
be exposures above the threshold at which humans are adversely affected, once
exposure is less than the threshold level, there are no adverse effects. However,
thresholds might be different for different individuals and identifying thresholds
for populations is more difficult |
