Segment Reporting Disclosure [Text Block] | NOTE 16 SEGMENT REPORTING In accordance with ASC 280, “Segment Reporting”, we define an operating segment as a business activity:
● | from which we may earn revenue and incur expenses;
● | whose operating results are regularly reviewed by the chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance; and
● | for which discrete financial information is available.
We currently have three reporting segments, which include Treatment and Services Segments, which are based on a service offering approach; and Medical, whose primary purpose at this time is the continuation of R&D of a new medical isotope production technology. The Medical Segment has not generated any revenues and all costs incurred are reflected within R&D in the accompanying Statements of Operations. Our reporting segments exclude our corporate headquarter and our discontinued operations (see Note 8 – “Discontinued Operations and Divestitures”) which do not generate revenues. The table below shows certain financial information of our reporting segments for 2015 and 2014 (in thousands). Segment Reporting as of and for the year ended December 31, 2015
