In connection with the acquisition of GPS, during the first quarter of fiscal 2010, the Company began to operate in two reportable segments, Radiation Monitoring and Medical Physics. Historically the Company operated in the Radiation Monitoring segment exclusively. The factors for determining the reportable segments include the products and services offered combined with the nature of the individual business activities, as well as key financial information reviewed by management.

The Radiation Monitoring segment provides analytical services to determine occupational and environmental radiation exposure. These services are provided internationally primarily to hospitals, medical and dental offices, universities, national laboratories, and nuclear facilities. Radiation Monitoring activities include the manufacture of various types of radiation detection monitors, the distribution and collection of the monitors to and from customers, and the analysis and reporting of exposure findings. In addition to providing analytical services, the Radiation Monitoring segment leases or sells dosimetry detectors and reading equipment.

The Medical Physics segment provides therapeutic and imaging physics services to domestic hospitals, free standing imaging centers and radiation therapy centers. Service offerings include clinical physics support, equipment commissioning, accreditation support and imaging equipment testing. These professional services are provided to customers on-site by skilled physicists. Medical Physics services are provided through the Company's GPS subsidiary.

The Company evaluates performance of the individual segments based upon, among other metrics, segment operating income or loss. Segment operating income or loss is segment revenue less segment cost of sales and segment selling, general and administrative expense. Corporate expenses for shared functions, including corporate management, corporate finance and human resources, are recognized in the Radiation Monitoring segment where they have been reported historically. In addition, acquisition and reorganization costs are not allocated to the segments. Information about net other income, including interest income and expense, and income taxes is not provided at the segment level. As the operational integration activities of the Medical Physics segment progress, including transaction processing, human resources and benefits administration, and sales and marketing activities, the Company expects to reevaluate the allocation of costs if or when these costs become material.

The following tables summarize financial information for each reportable segment:
