Image credit: Genevieve Martin, ORNL Neutron scattering for a better world eutron science began at Oak Ridge in 1944 when researcher Ernest Wollan took advantage of the world's first N continuously operating nuclear reactor—the X-10 Graphite Reactor—to study the diffraction of neutrons in a single crystal. In the intervening years, neutron scattering has proved to be an indispensable tool for scientific research, with neutron research at ORNL leading the way to such advances as better batteries, more effective drugs, and stronger armor for the military. The ability of neutrons to probe the magnetic properties of materials, to interact with light elements and to travel through materials that would stop X-rays or an electron beam make neutron scattering ideal for research areas ranging from quantum materials to biological systems to industrial applications in energy storage, automotive, aerospace and much more. Seven and a half decades after Wollan's groundbreaking work, ORNL is still at the forefront of neutron scattering research with two world-class facilities: the accelerator-based Spallation Neutron Source, which provides the world's most intense pulsed neutron beams, and the High Flux Isotope Reactor, which provides one of the highest rates of continuous-beam neutrons of any research reactor in the world. In the coming years, an upgrade to the SNS proton accelerator will double its power and increase the flux (quantity of neutrons) produced by SNS, and a second target station at the facility will add new research capabilities in complex materials and samples that need high resolution over a wide range of length and time scales. In this issue of ORNL Review, we look at the history of neutron research from early efforts to understand the atom to the present and beyond (see "Neutrons open a world of research," page 8), we explore the unique characteristics of neutrons and how they allow us to expand our knowledge (see "What makes neutron scattering unique," page 10), and we explain how upgrades at SNS will keep the United States at the cutting edge of neutron research for years to come (see "SNS upgrades will benefit researchers," page 12). Elsewhere in this issue, we profile nine extraordinary young researchers who have received prestigious early-career awards (see stories on pages 32 through 41). Seven received the DOE Early Career Research Award, a lab record and over a quarter of the 27 awarded to the 17 national laboratories. Two others received the Presidential Early Career Award for Scientists and Engineers, the U.S. government's highest honor for scientists and engi- neers in the early years of their careers. Also in this issue, we honor ORNL's Titan supercomputer, which was decommissioned this past August (see "Farewell, Titan: A long-running supercomputer with tremendous impact," page 18). Titan debuted as the world's fastest system in 2012, and as late as last June was ranked as high as number 12 in the world. Among its many achievements, it advanced the production of cellulosic ethanol and helped Southern California prepare for future earthquakes.

Box 100, A-1400 Vienna, Austria. Printed by the IAEA in Vienna April 2004 FOREWORD Occupational exposure to ionizing radiation can occur in a range of industries, such as mining and milling; medical institutions; educational and research establishments; and nuclear fuel facilities. Adequate radiation protection of workers is essential for the safe and acceptable use of radiation, radioactive materials and nuclear energy. Guidance on meeting the requirements for occupational protection in accordance with the Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (IAEA Safety Series No. 115) is provided in three interrelated Safety Guides (IAEA Safety Standards Series Nos. RS-G-1.1, 1.2 and 1.3) covering the general aspects of occupational radiation protection as well as the assessment of occupational exposure. These Safety Guides are in turn supplemented by Safety Reports providing practical information and technical details for a wide range of purposes, from methods for assessing intakes of radionuclides to optimization of radiation protection in the control of occupational exposure. Occupationally exposed workers need to have a basic awareness and understanding of the risks posed by exposure to radiation and the measures for managing these risks. To address this need, two series of publications, the Practical Radiation Safety Manuals (PRSMs) and the Practical Radiation Technical Manuals (PRTMs) were initiated in the 1990s.

  • Evaluation of Annual External Radiation Doses at Values Near Minimum Detection Levels of Dosimeters at the Hanford Nuclear Facility
    Journal of Exposure Analysis and Environmental Epidemiology (2000) 10, 27±35 # 2000 Nature America, Inc. All rights reserved 1053-4245/00/$15.00 www.nature.com/jea Evaluation of annual external radiation doses at values near minimum detection levels of dosimeters at the Hanford nuclear facility DAVID RICHARDSON,a STEVE WING,a JAMES WATSONb AND SUSANNE WOLFa aDepartment of Epidemiology, School of Public Health, University of North Carolina, Chapel Hill, North Carolina 27599 bDepartment of Environmental Science and Engineering, School of Public Health, University of North Carolina, Chapel Hill, North Carolina 27599 In epidemiological studies of workers exposed to ionizing radiation, recognition of the limitations of available radiation dosimetry data is important to interpretation of a study's findings. This paper provides an investigation of external radiation dosimetry data for workers at the Hanford nuclear facility, focusing on changes over time in practices for recording dosimetry measurements that were between zero and the minimum detectable level of a radiation dosimeter. Reported annual external radiation doses for the years 1944±1989 were examined for 33,459 workers; these records are the sum of periodic dosimetry measurements within a calendar year. For each year, the proportion of annual external doses with values in the range of minimum detectable level was examined. Contrary to previous researchers, we conclude that there is evidence that dosimetry measurements with values between zero and the minimum detectable level may have been recorded as zero in some historical periods. This conclusion is supported by evidence drawn from historical documentation about radiation dosimetry practices at the Hanford facility. Although workers at the Hanford facility have relatively complete and detailed external radiation dosimetry data compared to some other nuclear facilities that began operation in the 1940s, these data may suffer limitations related to dosimetry recording practices at the facility.

When the distance from the source of radiation is doubled, the amount of radiation received by the operator will be? a. Tripled b. Doubled c. The same d. Reduced by ½ e. Reduced by 3/4 Increasing the distance between the operator and the radiation source, will reduce exposure by the square of the distance from the source. Doubling the distance between the operator and the radiation source will reduc radiation exposure by a factor of 4. 2. During X-ray diagnostics, a staff member wears personal protective clothing – which of the following offers the best protection? a. an apron with a thickness of 0.25 lead-equivalent without a thyroid collar b. an apron with a thickness of 0.25 lead-equivalent and a thyroid collar c. an apron with a thickness of 0.35 lead-equivalent without a thyroid collar d. an apron with a thickness of 0.35 lead-equivalent and a thyroid collar e. an apron with a thickness of 0.15 lead-equivalent and a thyroid collar Lead aprons are the primary radiation protective garments used by staff during exposure to X rays. The radiation protection provided by a lead apron is approximately the same as 0.25- to 1-mm thick lead. Thicker aprons are usually more protective but heavier. An apron with 0.5-mm thickness can attenuate approximately 90% or more of the scatter radiation.

  • Radiation Hazard, Safety, Control and Protection Review Article
    Faridpur Med. Coll. J. 2019;14(2):100-103 Review Article Radiation Hazard, Safety, Control and Protection MH Rahman Abstract: The field of Radiology and Nuclear medicine has advanced from era of X-rays to today's modern imaging techniques, most of which use the ionizing radiation. With the benefits of better diagnosis and treatment, it has caused manifold increase in radiation exposure to the patients and the radiology and nuclear medicine personnel. Many studies done till date have clearly documented the harmful effects of ionizing radiation from radiation exposure, especially cancer. This is more important in paediatric population as their tissues are more radiosensitive, and they have more years to live. Diagnostic and therapeutic radiological procedures including nuclear medicine are integral part of modern medical practices, exposing both patients and medical staff to ionizing radiation. Without proper protective measures, this radiation causes many negative health effects. Hence, proper knowledge and awareness regarding the radiation hazards and radiation protection is mandatory for health professionals, especially the nuclear medicine and radiology professionals. International Commission on Radiation Protection (ICRP) has recommended two basic principles of radiation protection, justification of the practice and optimization of protection. Key words: Radiation, Hazard, Safety. Introduction: Ionizing radiation is a type of energy released by atoms gets inside the body. Staff must understand how they that travels in the form of electromagnetic waves are exposed to external radiation from radioactive (gamma or X-ray) or particles (neutrons, beta, alpha). sources, and how to avoid radioactive contamination on The spontaneous disintegration of atoms is called themselves or their personal clothing, or on work radioactivity, and the excess energy emitted is in the surfaces such as benches and counting equipment.
