The National Council on Radiation Protection and Measurements (NCRP), formerly the National Committee on Radiation Protection and Measurements, and before that the Advisory Committee on X-Ray and Radium Protection (ACXRP), is a U.S. organization. It has a congressional charter under Title 36 of the United States Code, but this does not imply any sort of oversight by Congress; NCRP is not a government entity. The Advisory Committee on X-Ray and Radium Protection was established in 1929. Initially, the organization was an informal collective of scientists seeking to proffer accurate information and appropriate recommendations for radiation protection. In 1946, the organization changed its name to the National Committee on Radiation Protection and Measurements. In 1964, the U.S. Congress reorganized and chartered the organization as the National Council on Radiation Protection and Measurements. Lauriston S. Taylor was an American physicist known for his work in the field of radiation protection and measurement. He established standards for X-ray radiation exposure for the first time in the 1920s. The first rigorously measurable field quantity, exposure, was defined in terms of specific instrument, the free-air chamber (FAC), introduced in the 1920s. FAC exposure standardization provided a sound foundation for external beam radiotherapy of the time, which was limited to x-ray spectra of 300 kVp. However, the FAC could not accurately measure 226 Ra exposure rates due to the difficulty of establishing secondary charged-particle equilibrium for high-energy (about 1.2 MeV on average) radium gamma rays. Dr. Wyckoff earned his Ph.D. in 1940 During WWII he supported operations research for the Ninth Air Force. After the war he returned to the National Bureau of Standards. After he retired from the Bureau he became Scientific Deputy Director of the Armed Forces Radiation Research Institute. He continue to consultant after his second retirement.…

Carl Bjorn Braestrup, worked on the Manhattan Project and was one of the first scientists to warn of the dangers of exposure to radiation. At the time he authored this work, he was associated with Columbia University and was a Member of the Executive Committee of the National Committee on Radiation Protection and Measurements. From an obituary posted on-line: "Dr Harold O. Wyckoff of Mitchellville, Md, a pioneer in the measurement and achievement of protection against radiation, died.at the age of 89 years on May 6, 1999. He was born in Traverse City, Mich, in 1910. During his long career, he was influenced by the discovery of new and more powerful radiations, a world war followed by a cold war, and international concern over the growing.applications of radiation. He came to the Washington, DC, area in 1940 after receiving degrees in physics from the University of Washington (Seattle), including a BS degree in 1934 and a PhD degree in 1940. In 1943, while working at the National Bureau of Standards, his services were sought because of war pressures. He was loaned to the U.S. Army, Ninth Air Force, to serve in Europe with the Operations Research Division.providing analysis and advice to the commanding generals of the Ninth Bomber and Fighter Commands. After the invasion of Normandy, France, he worked in this capacity close to the front lines at times. In 1945, President Truman awarded him the Bronze Star, one of the highest military awards given to a civilian. From 1941 to 1966, he was chief of the X-ray Standards Section, chief of the Radiation Physics Laboratory, and, later, assistant chief of the Radiation Physics Division at the National Bureau of Standards (now the National Institute of Science and Technology). From 1966 to 1971, he was the first scientific director of the Armed Forces Radiobiology Research Institute in Bethesda, Md, which was.deeply involved in studies of radiation effects and conditions.expected in the environment of a nuclear battlefield or a major nuclear attack on the country. From 1971 to 1974, he served as a consultant to the Bureau of Radiological Health.In addition to all of his duties in the United States, Dr Wyckoff was deeply involved with the International Commission on Radiation Units and Measurements (ICRU), the international authority on the quantities and units used for radiation measurement. He was a member of the ICRU from 1953 to 1956 and went on to serve as its secretary until 1969 and as its chairman until 1985.In the early 1970s, Dr Wyckoff was a member of the U.S. delegation to the United Nations Scientific Committee on the Effects of Atomic Radiation. Throughout his career in Washington, DC, he was active with the National Council on Radiation Protection and Measurements and was responsible for the introduction of radiation measurement as a part of its mission. He subsequently chaired several committees that produced reports covering radiation protection in the field of radiology. He was a member of the council's board of directors from 1966 to 1971 and was named an honorary member when he retired.In 1971, he was awarded a medal for exceptional civilian service from the Defense Atomic Support Agency. During his career, he published 44 scientific articles or book chapters. With Carl B. Braestrup, he co-authored Radiation Protection (Springfield, Ill: Thomas, 1958), which served as a standard text for students at that time. " Very good. No dust jacket.
