Immediately after the nuclear accident at Chernobyl, both the International Atomic Energy Agency (IAEA) and the Commission of the European Communities (CEC) set up a system to meet the requirements for early warning and exchange of information; the Emercom system for the IAEA and the ECURIE system for the CEC. Since several of the aims and needs for both systems overlap, it was decided to harmonise them as far as possible, in order to reduce the duplication of effort that might be required of personnel in member states, particularly in the stressful time immediately after an accident. This co-operation between IAEA and CEC resulted in the Convention Information Structure (C.I.Structure), a coding system by which radiological data are to be transmitted. In order to avoid language translation problems it was developed as a short code of specific meaning. Each type of message that might be transmitted is represented as a block of code. Within each block the parts of a message are labelled as line numbers. Since encoding or decoding messages in a manual way is a time consuming job and since it does not improve the reliability of the message contents, the C.I.Structure encoding-decoding software has been developed by the IAEA and the CEC.
