  • Main Attributes of Nuclides Presented in This Book
    Appendix A Main Attributes of Nuclides Presented in This Book Data given in TableA.1 can be used to determine the various decay energies for the specific radioactive decay examples as well as for the nuclear activation examples presented in this book. M stands for the nuclear rest mass; M stands for the atomic rest mass. The data were obtained from the NIST and are based on CODATA 2010 as follows: 1. Data for atomic masses M are given in atomic mass constants u and were obtained from the NIST at: (http://www.physics.nist.gov/pml/data/comp.cfm). 2. Rest mass of proton mp, neutron mn, electron me, and of the atomic mass constant u are from the NIST (http://www.physics.nist.gov/cuu/constants/index. html) as follows: −27 2 mp = 1.672 621 777×10 kg = 1.007 276 467 u = 938.272 046 MeV/c (A.1) −27 2 mn = 1.674 927 351×10 kg = 1.008 664 916 u = 939.565 379 MeV/c (A.2) −31 −4 2 me = 9.109 382 91×10 kg = 5.485 799 095×10 u = 0.510 998 928 MeV/c (A.3) − 1u= 1.660 538 922×10 27 kg = 931.494 060 MeV/c2 (A.4) 3. For a given nuclide, its nuclear rest energy was determined by subtracting the 2 rest energy of all atomic orbital electrons (Zmec ) from the atomic rest energy M(u)c2 as follows 2 2 2 Mc = M(u)c − Zmec = M(u) × 931.494 060 MeV/u − Z × 0.510 999 MeV.

Dial painting jobs did not require many skills but were well-paying professions. These careers attracted many young women and girls to work there. However, unknown to the painters at the time, the radium that they were using to paint the dial faces was slowly poisoning them and would later cause major health defects. Many of these women that did not die directly from the radium developed various forms of cancer and radium poisoning, which led to many lawsuits.

    Chapter 20 Detectors in Medicine and Biology P. Lecoq 20.1 Dosimetry and Medical Imaging The invention by Crookes at the end of the nineteenth century of a device called spinthariscope, which made use of the scintillating properties of Lead Sulfide allowed Rutherford to count α particles in an experiment, opening the way towards modern dosimetry. When at the same time Wilhelm C. Roentgen, also using a similar device, was able to record the first X-ray picture of his wife’s hand 2 weeks only after the X-ray discovery, he initiated the first and fastest technology transfer between particle physics and medical imaging and the beginning of a long and common history. Since that time, physics, and particularly particle physics has contributed to a significant amount to the development of instrumentation for research, diagnosis and therapy in the biomedical area. This has been a direct consequence, one century ago, of the recognition of the role of ionizing radiation for medical imaging as well as for therapy. 20.1.1 Radiotherapy and Dosimetry The curative role of ionizing radiation for the treatment of skin cancers has been exploited in the beginning of the twentieth century through the pioneering work of some physicists and medical doctors in France and in Sweden.

Jacobsohn (Advisor) Dr. John M. Ballato Dr. Colin D. McMillen i Abstract The effects of thermal post-fabrication processing in O2 flux on the luminescence and scintillation of Y2O3:Tm transparent ceramics were investigated. The material’s microstructure, optical properties, and scintillation properties were characterized using X- ray diffraction, attenuated total reflectance Fourier transform infrared spectroscopy, thermoluminescence measurements, differential pulse height distribution measurements, Archimedes density measurements, photoluminescence measurements, and ultra violet- visible transmission measurements. The processing is effective if performed in the time frame of 60-120mins at 1050°C under oxygen flow. After the first hour of processing, about 40% enhancement in the luminescence output together with about 20% enhancement in the scintillation light yield were observed.

  • Radium-226, Releases Half of Its Radiation in About 1,600 Years
    TOXICOLOGICAL PROFILE FOR RADIUM Agency for Toxic Substances and Disease Registry U.S. Public Health Service In collaboration with: U.S. Environmental Protection Agency December 1990 ii DISCLAIMER The use of company or product name(s) is for identification only and does not imply endorbement by the Agency for Toxic Substances and Disease Registry. 1 1. PUBLIC HEALTH STATEMENT This Statement was prepared to give you information about radium and to emphasize the human health effects that may result from exposure to it. The Environmental Protection Agency (EPA) has identified 1,177 sites on its National Priorities List (NPL). Radium has been found above background levels at 18 of these sites. However, we do not know how many of the 1,177 NPL sites have been evaluated for radium. As EPA evaluates more sites, the number of sites at which radium is found above background levels may change. The information is important for you because radium may cause harmful health effects and because these sites are potential or actual sources of human exposure to radium. When a radioactive chemical is released from a large area, such as an industrial plant, or from a container, such as a drum or bottle, it enters the environment as a radioactive chemical emission. This emission, which is also called a release, does not always lead to exposure. You can be exposed to a radioactive chemical when you come into contact with that chemical alone or with a substance that contains it. You may be exposed to it in the environment by breathing, eating, or drinking substances containing the radioactive chemical or from skin contact with it.

  • PRESERVATION SNAPSHOT Radium Girls
    PRESERVATION SNAPSHOT This monthly feature highlights National Register listings and eligible properties, tax act projects & compliance review success stories, as well as outstanding local efforts in New Jersey’s history. Radium Girls The Story of US Radium’s Superfund Site Orange, New Jersey US Radium Dial Painters, c. 1922 , Paint Application Building, 2nd floor Credit: Argonne National Laboratory At peak production during World War I, as many as 300 young women worked as ‘dial painters’ at their neighborhood US Radium Corporation plant in Orange, New Jersey. Seated at long benches on the second floor of the concrete Paint Application building with its large windows and skylights, they meticulously wielded minute brushes painting luminous paint on the numerals and hands of wrist watches and airplane cockpit dials. Within ten years, many would be dead. US Radium Corporation produced luminous paints and other radium products for military and medical purposes in Orange, NJ from 1917-1926. However, they operated with a dual set of health & safety standards. Their chemists and scientists were provided protective measures against exposure to the radioactive radium. The dial painters had no such measures in place. Nearly every surface inside their factory buildings sparkled with radioluminescence. Their supervisors told the dial painters the flavorless paint was perfectly safe, and encouraged them to “point” their camel hair brushes with their lips to keep a fine point. 1 Radium It was 1896 when Henri Becquerel discovered radium as a new element – Ra. Marie Curie and her husband, Pierre, jointly won the Nobel Prize with Becquerel in 1903 for their work on radioactivity.

Flakus* Ionizing radiation causes neutral atoms or molecules Emergence of radiation detectors to acquire either a positive or negative electrical charge. from the early discoveries The most commonly known types of ionizing radiation are alpha, beta, gamma, X, and neutron rays. On the evening of 8 November 1895, while working Charged-particle radiation, such as alpha or beta rays, in a carefully darkened room, Rontgen noticed that a has a direct ionizing effect; whereas neutral radiation, piece of a cardboard coated with barium platinocyanide such as X, gamma, or neutron rays, have an indirect showed a faint, flickering, greenish light (fluorescence) ionizing effect, i.e. these radiations first generate charged when electrical discharges took place in a Hittorf-Crookes particles which then have the ionizing effect. tube near the screen. The tube itself was carefully covered with a black shield impervious to any visible light. Radiation is a form of energy. This energy can be Rontgen verified that the tube was the source of a new partly or wholly deposited in a suitable medium and kind of radiation, which was invisible but which revealed thus produce an effect. The detection and measurement its existence when hitting the luminescent screen. of radiation is based upon the detection and Rontgen subsequently performed many careful experiments measurement of its effects in a medium, and the history on the radiation which he named X-rays.
