Best Medical International Inc. Prospective Buyer of Nordion Belgium Operations

OTTAWA, December 2, 2010 - Nordion Inc. (TSX: NDN; NYSE: NDZ), a leading provider of products and
services to the global health science market, today announced it has signed a
non-binding letter of agreement with Best Medical International Inc. for the
divestiture of MDS Nordion S.A.

The MDS Nordion S.A. operations currently support four lines of business
out of the Fleurus, Belgium location.

    - Agiris - Non-destructive testing equipment and sources
    - Glucotrace - FDG imaging agent
    - TheraSphere - Targeted liver cancer radiotherapeutic
    - Radiochemical business - Generic cyclotron and reactor isotopes

The Letter of Agreement for the divestiture will include three lines of
business and exclude the TheraSphere business which will be retained by
Nordion Inc. It is expected that proceeds received for the divested
operations will be nominal and that Nordion will leave sufficient working
capital in the business to support its operations through an initial
transition period.

During this process, MDS Nordion S.A. remains focused on continuing to
deliver quality product to its customers and managing the business

In July, 2010, Nordion initiated an Intention to Restructure of its
operations in Fleurus, Belgium. This announcement triggered a process
required under Belgium law to be conducted prior to any restructuring
activity decisions being taken. With the signing of this recent agreement,
the Intention to Restructure process will be paused until the negotiations
with the potential acquirer have concluded at which time a decision will be
made in the best interest of the Company and its employees.
