Commitments and Contingencies Disclosure [Text Block]	(7) Commitments and Contingencies Dependence on Third Parties The production of High Specific Activity Cobalt is dependent upon the U.S. Department of Energy (DOE), and its prime operating contractor, which controls the Advanced Test Reactor (ATR) and laboratory operations at the ATR located outside of Idaho Falls, Idaho. In October 2014, the Company signed a ten-year contract with the DOE for the irradiation of cobalt targets for the production of cobalt-60. The Company will be able to purchase cobalt targets for a fixed price per target with an annual 5% escalation in price. The contract term is October 1, 2014 through September 30, 2024. The Company is currently working on an extension to this contract. Also, the DOE may end the contract if it determines termination is necessary for the national defense, security or environmental safety of the United States. Sales of our most predominant Theranostics products are dependent upon a few key suppliers. An interruption in production by any of these individual suppliers could have an immediate negative impact upon radiochemical sales until material could be purchased from alternate suppliers including obtaining regulatory approval to use material from alternative suppliers if necessary. The Nuclear Medicine Reference and Calibration Standard products sold by the Company are dependent upon certain radioisotopes that are supplied to the Company through agreements with several suppliers. A loss of any of these suppliers could adversely affect operating results by causing a delay in production or a possible loss of sales. In six months ended June 30, 2024, there was a global shortage of Cobalt-57 isotopes, a key isotope for this business segment that resulted in significant lost sales. The Company has added additional suppliers in 2024 and continue to search for additional means to produce and procure certain critical isotopes, including through our Chinese Joint Venture. In July 2024, the Company began receiving Cobalt-57 from our main supplier again. We expect a revenue catch-up for the second half of 2024 and potentially into the first quarter of 2025 as we fulfill all pending orders that have been delayed due to the global shortage. Contingencies Because all the Company’s business segments involve the handling or use of radioactive material, the Company is required to have an operating license from the NRC and specially trained staff to handle these materials. The Company has amended this operating license numerous times to increase the amount of material permitted within the Company’s facility. Although this license does not currently restrict the volume of business operations performed or projected to be performed in the upcoming year, additional processing capabilities and license amendments could be implemented that would permit processing of other reactor-produced radioisotopes by the Company. The financial assurance required by the NRC to support this license has been provided for with a surety bond held with North American Specialty Insurance Company which is supported by a restricted money market account held with Merrill Lynch. In the six months ended June 30, 2024 the Company funded an additional $484,000 to this restricted money market account. At June 30, 2024, the balance of this account was $1,396,423. In August 2011, the Company received land from Lea County, New Mexico, pursuant to a Project Participation Agreement (PPA), whereby the land was deeded to the Company for no monetary consideration. In return, the Company committed to construct a uranium de-conversion and Fluorine Extraction Process facility on the land. In order to retain title to the property, the Company was to begin construction of the de-conversion facility no later than December 31, 2014, and complete Phase I of the project and have hired at least 75 persons to operate the facility no later than December 31, 2015, although commercial operations need not have begun by that date. In 2015, the Company negotiated a modification to the PPA that extended the start of construction date to December 31, 2015, and the hiring milestone to December 31, 2016. Those dates were also not met. On February 8, 2024, the Company entered into a definitive agreement to sell all of our assets related to the Fluorine Products segment and the Planned Uranium De-Conversion Facility, including the Lea County land, for an aggregate purchase price of approximately $12.5 million, subject to conditions. The Company expects to close the agreement within 12 to 24 months of signing. Closing is contingent on various conditions being met, including approvals and agreements by the NRC and other third parties. The Company has not recorded the value of this property as an asset and will not do so until such time that material changes to or sufficient progress on the project has been made to meet the Company’s obligations under the agreements for permanent transfer of the title.
