International Isotopes Achieves Major Milestone In Commercial 
Operation of LINAC  

- Upgraded Superconducting Super Collider LINAC Accelerates 
Beam -  

DENTON, Texas, May 14 /PRNewswire/ -- International Isotopes 
Inc (Nasdaq: INIS - news; BSE: ITL - news; III), a contract 
manufacturer of finished radiopharmaceuticals, producer of 
radioisotopes, pharmaceutical grade radiochemicals and medical 
devices, today announced final assembly and testing of the 
upgraded LINAC obtained from the Superconducting Super Collider, 
achieving the current operational objectives.  

The upgraded LINAC is capable of irradiating six targets 
simultaneously for the production of radioisotopes and 
radiochemicals widely used in nuclear medicine for diagnosis and 
therapy. These radioisotopes include Tl-201, I-123, In-111, Pd-103, 
Ga-67, Co-57, Cu-67, Cu-64, Zn-62 and other research nuclides 
which are used to satisfy a portion of the $170,000,000 
radioisotope and radiochemical market. These radioisotopes are 
the basis of the radiopharmaceutical industry and are used to 
provide finished radiopharmaceuticals for the $900,000,000 nuclear 
medicine diagnostic market.  

``'The Phoenix has risen from the ashes.' The LINAC was taken 
from the terminated Superconducting Super Collider program and 
has been upgraded, installed and placed in operation. This major 
portion of our business plan as set out in our IPO prospectus will 
greatly enhance shareholder value, future revenues and earnings,'' 
stated Dr. Ira Lon Morgan Chairman and Treasurer.  

``This event marks the achievement of another major objective for 
the start of commercial operation of the LINAC toward the goal of 
being a complete supplier of radioisotopes, radiochemicals, 
finished radiopharmaceuticals and brachytherapy medical devices 
needed for medical diagnostic and therapeutic applications,'' stated 
Carl Seidel President & CEO.  

``The achievement of this milestone is significant with respect to 
the commercial production of radioisotopes and radiochemicals. 
Our personnel has accomplished a monumental task in the 
upgrade, installation, testing and commissioning of the LINAC 
during the last seven months,'' stated Tommy Thompson, 
Executive VP & COO.
