BALTIC SEAENVIRONMENT PROCEEDINGS No. 59 - Helcom

power stations and from the Chernobyl accident. The report
will describe the monitoring network of the group MORS, the
assurance of quality of the data, and the temporal and spacial
evolution of artificial radioactivity in the various
compartments such as water, sediment and biota investigated
by the group EC MORS; the monitoring data will be used to
calculate inventories of radioactivity in the Baltic and to
model the radiation doses to humans by consumption of marine
food from the Baltic. It is expected that this report will be
ready by summer 1994.
CONCLUSION
The group EC MORS bases in its co-operation on the experience
gained during more than ten years including the IAEA CRP of
1981 to 1985. The group consists of a number of compentent
scientists of laboratories from all Baltic Sea States, which
were able to study the significant change of the inventory of
radioactivity during previous years in excellent international
co-operation. It was proved by several intercomparison
exercises that the data obtained by this expert group has a
very high quality standard. EC MORS is continuing its work as
a permanent expert group, in order to be able to detect any
harm to humans or biota caused by radioactive substances in
the Baltic Sea. Scientists from the new Baltic States are
cordially invited to co-operate in this group in the future
for exchange of knowledge in the field of monitoring of radioactive
substances.
