Nine-Months Revenue Increases 23% Compared to 2007; Gross Profit Percentage

Increases from 45% to 50% of Revenue

IDAHO FALLS, Idaho, Nov. 11 /PRNewswire-FirstCall/ -- International Isotopes Inc. (OTC Bulletin Board: INIS) announces financial results for the third quarter and nine-months ending September 30, 2008.

Revenue for the three and nine-month period ended September 30, 2008, was $1,245,164 and $4,429,144 respectively as compared to $1,486,112 and $3,592,049 for the same periods in 2007, a decrease of $240,948, or 16%, for the three-month period and an increase of $837,095, or 23%, for the nine-month period. The increase in total revenue for the nine-month period was attributable to strong performance in cobalt and radiochemical product business segments. The decline in revenue for the three-month period was attributable to normal variations in the sale of bulk cobalt for the period comparisons. Since the timing of large bulk cobalt product sales during the course of the calendar year has a significant impact upon period comparisons, the Company believes excluding sales of bulk cobalt product from the period comparisons of revenue provides useful information to investors.

Excluding bulk cobalt sales, revenue for the three-month period ended September 30, 2008 was $1,245,164 as compared to $1,038,835 for the same period in 2007, which represents an increase of 20%. Excluding bulk cobalt product sales, revenue for the nine-month period ended September 30, 2008 was $3,940,888 as compared to $3,144,773 for the same period in 2007, which represents an increase of 25%.
