Abstract
Over recent years, it has been
established that deposition of various types of pollutant aerosols (e.g.,
radioactive) on human skin can have serious deleterious effects on health.
However,
only few investigations in the past have been devoted to measurement of deposition
velocities on skin of particles of the potentially problematic sizes.
An
experimental programme has shown the deposition velocities on skin of particles
in the ca. 0.5e5 mm AMAD range to be high and generally associated with great
variations. A series of investigations have been made to identify some of the
factors that lead to this variation. Part of the variation was found to be
caused by differences between individuals, whereas another part was found to be
related to environmental factors.
The identification of major influences on
skin contaminant deposition is important in estimating health effects as well
as in identifying means for their reduction.
Excerpted from Article:
“Until the late
1990s, surprisingly little attention had been given to the implications of
contaminant aerosol (either radioactive or non-radioactive) depositing on human
skin. Consequently, published data were at that point far too sparse to allow
reliable nuclear emergency consequence modelling. By 1998, the severity of this
problem had been recognised by, for instance, the developers of the European
standard model COSYMA (Jones et al., 1998), and an experimental
project had been initiated to investigate the mechanisms governing both beta
and gamma doses from deposition of contaminant aerosol on the human body (Fogh
et al., 1999; Fogh and Andersson, 2000; Andersson et al., 2002).
