ICNIRP was pleased to organize the "International
Workshop on UV exposure guidance", 17-18
October 2005, Munich, Germany. The Workshop was
hosted by the German Radiation Protection Office
(BfS) and co-sponsored by the German Federal Ministry
for the Environment (BMU), WHO and EuroSkin. The
proceedings are published in the Journal "Progress
in Biophysics and Molecular Biology", 92(1);
July 2006 - ISSN 0079-6107.
Rational: UV-exposure is well recognized as the
main cause of skin cancer. As a consequence, sun
protection is required at times and locations
where the UV radiation levels are high. Many international
and national public health programmes are engaged
in sun protective measures in order to reduce
the risk of skin cancer. This is of utmost importance
in countries where the incidence of skin cancer
has been increasing mainly due to changing recreational
activities and behaviour.
Small amounts of sun exposure are essential to
good health. Vitamin D, which is produced in the
skin by exposure to ultraviolet B, regulates calcium
levels in the blood and is needed for bone and
musculoskeletal health. Only recently, some epidemiological
studies supported the beneficial effects of sun
exposure by revealing a link between a number
of cancers and low Vitamin D levels. The studies
suggest that sun exposure might reduce the risk
of certain cancers or increase the survival rates.
Even if the mechanisms underlying the observed
associations are not yet known, it is necessary
to work on a balance between avoiding skin cancer
and maintaining optimal vitamin D status.
It has been estimated, that most people in most
countries achieve adequate Vitamin D levels by
normal outdoor activities. However, studies on
the quantitative relationship of sun exposure
and Vitamin D synthesis are rare. Increasing age
and dark skin types are frequently correlated
with Vitamin D deficiency.
The workshop brought together experts in the field
of radioprotection and Vitamin D. The contributions
of the invited speakers are published as Proceedings
in the Journal "Progress in Biophysics and
Molecular Biology", 92(1); July 2006 - ISSN
