even speculating on the require­ ments for bringing N M R / R D to the point of a workable instrument with commercial viability. This writer feels that nuclear chemistry is being assimilated into our science and educational system at much too slow a rate, especially in an era of exponential growth in population and knowledge. An ex­ cellent article by Peter C. Goldmark (Trans. New York Acad. Sci., May 1969, ρ 584) brings this into sharper focus: "Nuclear explosions, put to such peacetime uses as the creation of rivers and lakes, will be one of the forces used to provide suste­ nance for the Earth's increasing population." Consonant with this thesis is the need for nuclear studies in every phase of scientific achieve­ ment and related human require­ ment ancillary to the sheer move­ ment of tons of the Earth's matter. Geochemical exploration, environ­ mental and life sciences, industry, and agriculture benefit directly from nuclear chemistry. The disturbing facts are that 70% of the chemistry departments in this nation have no nuclear chemists at all, and 70% of the total number of academic nuclear chemists are clus­ tered in 11% of the 134 PhD-granting departments (data from "Nu­ clear Chemistry—A Current Re­ view," National Academy of Sci­ ences, Washington, 1966). This very low distribution of persons knowledgable in nuclear chemistry in our universities is due in part to the limited number of major equip­ ment installations (reactors or ac­ celerators) and in part to the very low total number of people qualified by education to teach nuclear chem­ istry" (2% of Ph.D.'s in chemistry, 10% of all Ph.D.'s in nuclear struc­ ture research). Only limited success has been achieved at bringing the study of the nucleus—and a familiarity with nuclear chemistry—into the high school and beginning college levels. College general chemistry textbooks often relegate nuclear chemistry to one of the last—if not the last chap­ ter. John K. Crum

Isolate Na, K, Hg, Li with Confidence When you use Laser Optics Isolation Filters (l-F's) for chemical analysis, you expect and get positive indication of hard to isolate elements. Even calcium in blood serum can be easily identified using l-F's with flame techniques. Strong signal to noise ratios typify all l-F's and make pos­ sible precision electro-optical detection or sensing sys­ tems of simplified design. You can identify with confidence a wider range of ele­ ments and compounds than ever before possible with your electro-optical system. All l-F's retain their integ­ rity in unfriendly environments such as high humidity. Even high ultraviolet (UV) energy will not degrade their performance. These filters are designed for any electro-optical detection or sensing system operating in the Ultraviolet (UV), Visible (VIS) or Infrared (IR) frequency ranges. They are described in a new LOI bulletin entitled l-F's — High Performance Isolation Filters. Write or call Laser Optics, Inc. for your free copy and a quotation.
