This summary document on nitrogen (nitrate, nitrite and ammonia) is one in a series which establishes ambient water quality guidelines (criteria) for British Columbia. These are used to set ambient water quality objectives to protect the most sensitive designated water use in a specific body of water. Use may be in the preparation of waste management plans, waste management permits, orders or approvals. The water uses protected include raw drinking, public water supply and food processing water, aquatic life and wildlife use, agricultural use including livestock watering and irrigation, recreation and aesthics and industrial water supplies.

Evolutionary changes in educational food service operations progess from the self-operated, straight-line service of pre- World War II through food service management firms' marketing efforts toward pleasing students; through the creation of the National Association of College and University Food Services and increased demand for hotel/restaurant management academic programs to the present. Current influences cited are: increased usage of a la carte service to limit waste factors; and development of innovative foods, packaging, equipment, and food handling techniques which contributed to a more varied menu. Trends such as increased demand for on-campus housing and larger college (student) unions are forecasted to influence the future of educational food service.(mjs)

Abstract: A comprehensive technical handbook emphasizes various aspects of radiation safety from the regulatory of management standpoint, gleaned largely from past experiences covering early mistakes, radiation litigation, or in the aftermath of the Three Mile Island accident. The 9 text chapters, prepared by experts in their respective fields, cover; experiences in radiation litigation; public relations in health physics; appropriate methods for disseminating information concerning radiation and nuclear power to the public; radioactive waste management; operational aspects and strategies of a radiation safety office; methods for radiation emergency planning and radiation damage control; predetermined conditions and actions for planing emergency response decisions; and methods of radioactive materials transport. | Extensive information on federal and state regulations concerning the shipping of radioactive materials is provided in 23 appendices, which comprise 45% of the text. The text material is directed toward: industrial, academic, medical, and governmental institutions and public health officials; scientists, engineers, and applied health physicists concerned with radiation safety programs; and toward physicians involved in caring for patients exposed to radioactive materials.
