                           INTERNATIONAL ISOTOPES INC.

                                   THE COMPANY

International  Isotopes  Inc., a Texas  corporation,  (together  with its wholly
owned subsidiary, International Isotopes Idaho Inc. ("I4") hereafter referred to
as "we" or the "Company" or "I3") was initially formed as a Texas corporation in
1995 to produce,  market,  and  distribute  a broad  range of  products  used in
diagnostic and therapeutic nuclear medicine, research, and industry. In 2001, we
changed  our  mission  and  business  strategy  somewhat  to  focus  upon  other
radioisotope  products,  manufacture  calibration  and  reference  standards for
nuclear medicine,  and provide general radiological  measurement  capability for
processed  gemstones.  In 2003,  we put two new supply  agreements  in place for
Lu-177 and I-131  radioisotopes and expanded our processing  facility to include
processing and  distribution  capability  for these new isotopes.  The following
paragraphs provide some additional details on our various business areas.

Radioisotope Products

We  offer  a  selection  of  radioisotopes   and   radiochemicals   for  various
applications   including  clinical  research,   life  sciences,  and  industrial
applications.  In the past  these  isotopes  have  included  Cobalt-60  (Co-60),
Cobalt-57 (Co-57),  Cesium-137  (Cs-137),  and Barium-133  (Ba-133),  which were
typically  sold  as  radiochemicals  to be used in the  manufacture  of  various
reference or  calibration  standards  for industry or  medicine.  The  Cobalt-60
isotope  produced  by the  Company  is unique  in that it is very high  specific
activity material.  This high specific activity material can only be produced in
a few  nuclear  reactors  around  the  world  such as the  Department  of Energy
Advanced Test Reactor at the Idaho  National  Laboratory,  to which we currently
have  access.  This high  activity  cobalt is sold in bulk to  General  Electric
Nuclear who in turn fabricates sealed sources for the Leksell gamma knife.

During  2003 we put two new  supply  agreements  in place  with two  independent
producers  to supply  the  additional  isotopes  of  Lutetium-177  (Lu-177)  and
Iodine-131 (I-131)  radiochemical.  Lutetium-177 is currently being investigated
in several different clinical applications  including treatment of colon cancer,
metastic  bone cancer,  Non-Hodgkin's  Lymphoma,  and lung cancer.  In published
cancer statistics,  it is estimated that there are over half a million new cases
of these cancers  occurring  each year in the U. S. and nearly two million cases
worldwide.  Clinical  research  with  Lutetium-177  has been ongoing for several
years  and the  isotope  has  demonstrated  certain  chemical  and  radiological
properties  which  make it  potentially  very well  suited  as a cancer  therapy
product.  We are  obtaining  our  Lutetium-177  through  an  agreement  with the
University  of  Missouri  Research  Reactor  (MURR),  which  has been a  leading
developer of radioisotopes  suitable for patient trials and has also been a very
reliable production source for these isotopes.

Also in 2003,  we entered  into a  distribution  agreement  with a major  global
supplier  of  Iodine-131   radiochemical  and  started   distribution  in  2004.
Iodine-131 is currently being used on a large  commercial  scale within the U.S.
for the  treatment  and  diagnosis  of various  diseases of the thyroid  such as
Graves disease,  thyroid cancer, and  hyperthyroidism.  Iodine-131 is also being
used in a host of investigational  and clinical trials such as for the treatment
of breast, lung, prostate, and ovarian cancers.



                                       3


Calibration and Reference Standards

We are a contract  manufacturer  for a wide range of NIST traceable  calibration
standards and Quality  Assurance check sources for various nuclear  pharmacy and
SPECT related  equipment.  These items include flood sources,  dose calibrators,
rod sources, flexible and rigid rulers, spot markers and penpoint markers. I3 is
an exclusive contract manufacturer for Radqual LLC for these products. There are
over 5,000 nuclear  medicine centers around the country that require these types
of products on a regular basis.

General Measurement and Radiological Services

The Company provides a host of analytical,  measurement, and processing services
on a contract basis to clients.  Some of these services offered include detailed
radioactivity  analysis,  gamma assay, ICP analysis,  Type A package development
and testing,  and Health Physics consulting.  The largest single product service
in this area involves our packaging and post irradiation examination process for
gemstone that has undergone  irradiation for color  enhancement.  We have had an
exclusive contract with Quali-Tech Inc. since 2001 to provide this service.

Fluorine products

We initiated  evaluation and  acquisition in 2003 of seven patents related to an
entirely new product line for the Company - fluorine  extraction  process (FEP).
We closed this acquisition on January 30, 2004. The FEP patents and intellectual
property will be used for  production of several high purity  fluorine  products
and we will establish a new fluorine  products  division to capitalize upon this
technology.

High purity fluorine gases are in ever-increasing demand for ion-implantation or
chemical  vapor  deposition  processes  for   microelectronics   components  and
high-speed  silicon chip  manufacture.  The FEP fluorine  product is equal to or
greater than 99.99% pure with no  detectable  uranium in the product  gas.  This
makes our FEP products  ideally  suited to these  specialty  applications  where
ultra high purity  gases are  required.  In  addition,  we  anticipate  that the
production  costs of FEP  products  will be low in  comparison  with  ultra pure
fluorine products  manufactured by other common commercial methods,  enabling us
to effectively compete with existing high purity fluorine product suppliers both
on cost and purity.

To support the start-up of FEP we have entered into a marketing  and  technology
consulting  agreement with  individuals  knowledgeable  and experienced with the
processing  technology  and market  applications  for FEP products and leased an
additional  industrial facility for production of FEP gases. We believe that the
market size and growth  outlook for high purity  fluorine  products is excellent
and should provide the Company an opportunity to grow our revenue  substantially
in coming years.


                                       4


We believe  that  revenues  generated  from  these  business  activities  can be
expected to have a positive effect upon our projections for continued  growth in
2004 and should produce sufficient cash to meet our operational needs.  However,
prospective  investors are cautioned  regarding  the  speculative  nature of any
forward-looking projections. Also see "Risk Factors," below, for a discussion of
these and other  risk  factors  relating  to the  Company  when  considering  an
investment in our securities.

Company Licensing, Capabilities, and Qualifications

We are a  participating  member  of the  National  Institute  of  Standards  and
Technology/ Nuclear Energy Institute's  (NIST/NEI) Measurement Assurance Program
(MAP) for the  radiopharmaceutical  industry. This program participation ensures
that we can provide  analytical  methods and  standards  necessary  for accurate
radioactivity  measurement  and  is a  requirement  for  most  of  the  products
manufactured for nuclear medicine  reference and calibration  standards.  We are
also a registered Food and Drug Administration (FDA) medical device manufacturer
for  Class I medical  devices,  including  Nuclear  Sealed  Calibration  Sources
(892.1400)  and  Nuclear  Flood  Source  Phantoms  (892.1380),  and have a fully
implemented  Quality Assurance program which meets the requirements of ANSI/ASME
NQA-1 and 10 CFR 830.120.

We have an operating license issued from the Nuclear Regulatory Commission which
defines  the types and amounts of  radioactive  materials  permitted  within our
facility.  In 2003  the  Company  completed  two  additional  revisions  to this
licensing to allow expanded  production of our new  radioisotopes,  Lutetium-177
and Iodine -131.

Industry Overview, Target Markets, and Competition

The  industries  and  markets  that  require or involve  the use of  radioactive
material are diverse. Our current operations involve products that are used in a
wide variety of applications and in various markets.

Radioisotope  products  are  supplied  typically  in a bulk form and are  highly
competitive.  The  target  market's  for these  products  are  customers  who 1)
incorporate  them into  finished  industrial  or  medical  devices  2) use these
products in  clinical  trials for various  medical  applications,  or 3) further
process and include the material into a pharmaceutical  product for FDA approved
therapy or imaging.

Calibration  and  Reference  Standards  are required  for the daily  operational
checks and calibration of the  measurement of SPECT imaging  devices  frequently
used in nuclear  medicine.  This  calibration and quality  assurance  testing is
required as a routine part of the normal  operations of this equipment to ensure
its  reliability  and accuracy.  We exclusively  manufacture  these products for
Radqual LLC, which in turn sells the products to several distributors around the
U.S. We directly ship these products to all 50 states and Canada.  There are two
other major  producers of these products  within the U.S. that directly  compete
with us for these products.



                                       5


Most of our general  measurement  and  radiological  services  are  performed in
support of gemstone processing. This material has undergone color enhancement by
irradiation at the University of Missouri  Research  reactor.  The gemstones are
used  in  commercial  jewelry   manufactured  by  other  companies  in  overseas
locations.  The color enhancement  process is a highly competitive  industry and
there are several  alternatives to irradiation  treatment.  There are also other
reactors  located in other regions of the world that also offer this irradiation
service  capability.  The  jewelry  manufacturing  industry  is  also  a  highly
competitive industry.

We are developing our fluorine products in 2004 to address an opportunity we see
in the increased market demand for certain high purity fluorine compounds in the
microelectronics  industry.  Emerging  technologies such as the increased use of
silicon  germanium  processing chips for the wireless  industry will require the
use of high purity fluorine compounds such as germanium tetra fluoride.  We plan
to establish some manufacturing  capacity for at least one of these compounds in
2004.  Several of these fluorine compounds are already under production by other
businesses. Since the cost of the FEP process is low we anticipate being able to
be very  price  competitive  with our  fluorine  products.  However,  this price
advantage may initially be our only competitive advantage in this market.

Government Regulation

The  Company has  obtained a license  from the  Nuclear  Regulatory  Commission,
Region IV that permits use and possession of by-product  material.  The scope of
this license  includes  calibration  and reference  standard  manufacturing  and
distribution,  radioisotope  processing and distribution,  radioactive  gemstone
processing,  environmental sample analysis, and various research and development
activities.  The existing  license and permit's are adequate to allow all of our
business  operations.  Expansion  into FEP  production  will require  additional
permitting both through the NRC, State of Idaho, and the EPA. We will make every
effort to prepare well planned and detailed  applications  for these  additional
permits,  however,  there can be no assurance of the time frame required for the
various governmental agencies to review and approve these permits.

Regulation of Radioisotope Production Radioactive Waste

All of our manufacturing  processes result in the generation of some radioactive
waste. We must handle these wastes pursuant to the Low Level  Radioactive  Waste
Policy Act of 1980,  which states we are required to assure the safe disposal of
mildly  radioactive  materials.  The estimated costs for storage and disposal of
these materials have been included into the manufacturing and sales price of our
products. However, actual disposal costs are subject to change at the discretion
of the disposal  site and are  ultimately  applied at the time of disposal.  The
operating  permit from the NRC also  requires  that we maintain an adequate cash
reserve,  in the form of a  certificate  of deposit  and  irrevocable  letter of
credit to the NRC to support our estimated  decommissioning  and disposal  costs
for the facility.  We do not handle "special nuclear  materials"  (i.e.  nuclear
fuels and weapons grade uranium,  thorium and  plutonium)  and,  therefore,  our
facility is not designated as a "nuclear" facility.



                                       6


Other Regulations

Our sale of the isotopes  Lutetium-177 and Iodine -131 for medical  applications
could  cause us to be subject  to  additional  regulations  of the Food and Drug
Administration (FDA). The Company is registered as a medical device manufacturer
through  the  U.S.  FDA  for  several  of our  nuclear  medicine  reference  and
calibration standards.


                                  RISK FACTORS

An investment in the securities  offered hereby  involves a high degree of risk.
In addition to the other  information  in this  Prospectus,  the following  Risk
Factors  should be  considered  carefully in  evaluating  an  investment  in the
securities offered hereby.

International  Isotopes has incurred and may continue to incur losses.  With the
exception of the three-month and six-month  periods ended June 30, 2002, we have
incurred net losses for most fiscal periods since our inception.  From inception
(November 1995) through December 31, 2003 the Company  generated  $19,316,817 in
revenues and had an accumulated deficit (including preferred stock dividends and
returns) in the amount of $87,968,650.  However,  although we cannot provide any
assurance  we  believe  the  Company's  continued  growth  and our new  business
products  will  produce  sufficient  revenue  to meet  our  2004  cash  flow and
operational needs.

We may need additional financing to continue operations. As of December 31, 2003
we have an  outstanding  debt of  $733,595 on a short term note with Texas State
Bank.  That note  matures on February 1, 2006 and is secured  with our  accounts
receivable  and fixed assets.  The Company also has a ten-year note for $840,753
at 7%  interest  to our former  Chairman of the Board.  Principal  and  interest
payments  on this note are to be paid  annually  based  upon net  profits of the
Company (annual principal payment to equal 30% of net pre-tax profits).

Remaining  Company  Obligations  on the Texas State Bank Loan for the Waxahachie
Property.  In 2002 the  Company  and Texas  State  Bank  agreed to have our loan
assumed  by an  individual  in  consideration  of our  sale  of  the  Waxahachie
property. As of December 31, 2003 the remaining outstanding balance on this loan
was $329,357.  Should this individual default on the assumed note, the liability
for the loan would revert to the Company.

We will continue to be dependent upon our remaining  facilities and equipment to
function properly in order to provide  consistent,  timely shipments of products
that meet our customers' specifications.  If we experience equipment failures or
breakdowns we may be unable to satisfy our customers,  which could result in the
cancellation of contracts and the loss of revenues.

There is no long-term  contract in place with the DOE  Contractor  for continued
HSA  Cobalt  production.  The  Company  has put short  term  specific  "work for
non-government  sponsor agreements" in place with the DOE contractor to continue
sales of HSA cobalt  irradiated  at the Idaho reactor  facility.  We expect that
these agreements will continue,  however,  there is no assurance these contracts
will be equitable or continuing.

Operational hazards (i.e.,  spills,  faults,  ventilation  failure,  etc.) could
result in the spread of contamination within our facility and require additional
funding to correct. An irrevocable, automatic renewable letter of credit against
a $150,000  Certificate  of Deposit at Texas State Bank has been used to provide
the financial  assurance required by the Nuclear  Regulatory  Commission for our
Idaho facility license.  If a contamination  event resulted in greater liability
to us we  would  have to  borrow  money or fund the  liability  from our  future
revenue.


                                       7


Government regulation could adversely affect our business. Operations within our
Idaho facility are subject to the U.S.  Nuclear  Regulatory  Commission and Food
and Drug Administration regulations.  Nuclear medicine calibration and reference
standards are licensed and  regulated.  To the extent these  regulations  are or
become burdensome, our business development could be adversely affected.

We are dependent  upon key  personnel.  Our ongoing  operations are dependent on
Steve T. Laflin,  President and Chief Executive  Officer.  The Company is highly
dependent upon this person and the loss of this individual could have a material
adverse effect on us. We have a $2 million dollar key man life insurance  policy
on Mr.  Laflin and a 5-year  employment  agreement  with him  extending  through
February 2007. The Company has revised our employee stock options to assist with
offering  incentives  and  retaining  key  personnel.  In addition,  there is no
assurance  the Company will be able to retain our existing  personnel or attract
additional qualified employees.  Loss of any of these relationships would result
in a significant decline in revenue.

We are  dependent  on various  third  parties in  connection  with our  business
operations.  The  production of HSA Cobalt is dependent  upon the  Department of
Energy, and its prime-operating  contractor,  who controls the Idaho reactor and
laboratory operations. Our gemstone production is tied to an exclusive agreement
with Quali Tech Inc.  and this  current  agreement  expires  in  November  2004.
Nuclear medicine  calibration and reference standard  manufacturing is conducted
under an exclusive  contract with RadQual,  LLC, which in turn has agreements in
place with several companies for marketing and sales.

We are subject to competition from other  companies.  Each of the business areas
of the  Company  has direct  competition  from other  businesses.  HSA cobalt is
supplied  by  other  reactor  facilities  around  the  world.  Nuclear  medicine
calibration  and  reference  standards  are  being  produced  by  several  other
manufacturers in the U.S. and overseas, and there is at least one other gemstone
processor in Europe.  Lutetium-177  and I-131 isotope is manufactured by several
other companies in the world,  and there are also other suppliers of high purity
fluorine products.  Each of our competitors has significantly  greater financial
resources  than us and that could create a  competitive  advantage for them over
us.

We are named as Defendant in a lawsuit filed by Iso-Science  Laboratories Inc. A
lawsuit has been filed by Iso-Science  Laboratories,  Inc. dba Isotope  Products
Laboratories  against  International  Isotopes  Inc.  and  others.  The  Company
believes the  allegations of the petition are totally  without  merit.  However,
there can be no guarantee of the outcome of this suit and an unfavorable outcome
could  result in the loss of a major line of revenues  and  require  substantial
payments to the Plaintiff.
