The RATEMA project is an international cooperation between the University o
f Ulm in Germany and the Urals Research Centre for Radiation Medicine in Ch
elyabinsk, Russia. For one year we conducted weekly conferences between the
two sites, based on a satellite link with a 384 kbit/s connection. During
the videoconferences the physicians on both sides-experts in radiation medi
cine-discussed the health status of Russian patients who had been chronical
ly exposed to ionizing radiation in the South Urals region. The German part
ners presented patients with comparable haematological and oncological dise
ases. The project has shown the advantages and difficulties of working in a
n international and interdisciplinary environment. The experience gained ha
s been very valuable for planning new projects with similar tasks. The resu
lts and the contents of the RATEMA database are the basis for education and
research for physicians involved in the management of radiation victims.
