International Isotopes Inc. Announces Execution of an Agreement With the State
of New Mexico Environment Department

IDAHO FALLS, Idaho, Oct. 26 /PRNewswire-FirstCall/ -- International Isotopes
Inc. (OTC Bulletin Board: INIS) announces it has entered into an Agreement
with the State of New Mexico Environment Department (NMED) that establishes
mutually agreed upon license limits for INIS's planned uranium de-conversion
and fluorine extraction processing facility. The completion of this Agreement
is an important step towards licensing and constructing a uranium
de-conversion and fluorine extraction processing facility in the State of New
Mexico.

International Isotopes announced the selection of Hobbs, New Mexico as the
site for the uranium de-conversion processing facility this past March. Prior
to, and since that time, the Company has been working diligently to address
regulatory issues associated with the facility and educating the public and
investment community about the important "green" ecological aspects of the
facility. The facility is expected to have a significant positive economic
impact in New Mexico and public support for the project remains strongly
positive. The Company has been active in working with the State of New Mexico
and local area residents since site selection to ensure continued
understanding of the project and its benefits to New Mexico and to the nuclear
industry.

Steve Laflin, the Company's President and CEO said," This Memorandum of
Agreement is important for two reasons. First, it represents completion of an
important step in the preparation of the NRC license application. Second, it
typifies the Company's continued commitment to protecting the environment and
working closely with NMED to ensure project transparency and regulatory
cooperation. The Agreement implements certain terms for the facility that
have been mutually agreed upon. Both parties have agreed that these terms
will be incorporated into the Company's Nuclear Regulatory Commission (NRC)
license application and eventually into the NRC license itself, where
applicable."

Ron Curry, New Mexico Cabinet Secretary for the Environment Department, stated
"We've diligently worked out an agreement that will protect the state and the
citizens of New Mexico into the future while also allowing International
Isotopes to operate here. The agreement exceeds specifications for the
facility that New Mexico could have achieved through the federal licensing
process. We are gratified to reach an agreement that stipulates no waste from
the facility will be disposed within the State of New Mexico."

The INIS facility is planned for a location about 15 miles west of Hobbs, New
Mexico and will consist of both depleted uranium de-conversion and fluorine
gas extraction processes. INIS holds patents that give it exclusive rights to
the Fluorine Extraction Process (FEP), which produces high value, high purity
gases in conjunction with uranium de-conversion, and thus, provides a key
commercial advantage to the de-conversion plant. INIS expects to hire about
150 construction workers for the project and anticipates that it will
eventually have a full time staff of approximately 130 to 150 employees for
plant operations. Construction of the facility is anticipated to begin in the
third quarter in 2011, after Nuclear Regulatory Commission licensing is
complete, and to begin operations in late 2012.
