Segment Reporting Disclosure [Text Block] | 10. Operating Segments In accordance with ASC 280, “Segment Reporting”, the Company defines an operating segment as a business activity: (a) from which we may earn revenue and incur expenses; (2) 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 (3) for which discrete financial information is available. Our reporting segments are defined as below: TREATMENT SEGMENT reporting includes:
| - | nuclear, low-level radioactive, mixed, hazardous and non-hazardous waste treatment, processing and disposal services primarily through four uniquely licensed and permitted treatment and storage facilities; and
| - | R&D activities to identify, develop and implement innovative waste processing techniques for problematic waste streams.
SERVICES SEGMENT, which includes:
| - | On-site waste management services to commercial and government customers;
| - | Technical services, which include:
| o | professional radiological measurement and site survey of large government and commercial installations using advanced methods, technology and engineering;
| o | integrated Occupational Safety and Health services including industrial hygiene (“IH”) assessments; hazardous materials surveys, e.g., exposure monitoring; lead and asbestos management/abatement oversight; indoor air quality evaluations; health risk and exposure assessments; health & safety plan/program development, compliance auditing and training services; and Occupational Safety and Health Administration (“OSHA”) citation assistance;

MEDICAL SEGMENT reporting includes: R&D costs for the new medical isotope production technology from our majority-owned Polish subsidiary, PF Medical. The Medical Segment has not generated any revenue as it continues to be primarily in the R&D stage. All costs incurred for the Medical Segment are reflected within R&D in the accompanying Consolidated Statements of Operations and consist primarily of employee salaries and benefits, laboratory costs, third party fees, and other related costs associated with the development of this new technology. Our reporting segments exclude our corporate headquarters and our discontinued operations (see Note 9 – “Discontinued Operations”) which do not generate revenues. The table below presents certain financial information of our operating segments for the three and six months ended June 30, 2016 and 2015 (in thousands).
