OFFICIAL USE ONLY reactors for research, medical therapy and energy. The public is becom ing increasingly alarmed with plans for reactors in populated areas and the attendant danger, A single comprehensive authoritative manual would greatly relieve apprehension and also serve to prevent the development of a heterogeneous series of codes and regulations by many independent groups, An example of the unavoidable situations that arise because of this void on our health physics staff is the Borax reactor incident at Idaho where the Biophysics Branch received its information after-the-fact from, oddly enough, the Weather Bureau, Dr, Claus stressed the point that more assistance in these areas of responsibility is nceded, Trends in the Radiation Instruments Program Mr. Butenhoff reviewed the trends in the radiation instruments program and prefaced his remarks by reading the following excerpts from an article by Dr, A, V. Astin, Director, National Bureau of Standards, which had been published in the Scptember issue of "The Journal of the Instrument Society of America", "The impact of instrumentation is extremely wide, affecting not only science and engineering but also manufacturing, commerce and government activities. Measurement is so important to the progress of science that all scientists sooner or later become involved in some phase of an instrument problem, With the increased range and complexity of science, the limit as to what can be observed or studied is frequently set by the characteristics of available instruments, ~16 = OFFICIAL USE ONLY The
