WADMAN III .ri-- :?-.\:Kx.:-i ;S Uf»:ji, PREFACE Radiation Instrumentation is an essential part of health physics. Opera- tional monitoring is impossible without it. The H.P.S. Eleventh Midyear Topical Symposium addressed the need to exchange state of the art instru- mentation information with coverage of laboratory and field applications of it in operational and research areas of health physics. These proceedings have been published after the meeting, held January 16-19, 1978 to enable the editor the tune to include questions and answers-in essence-peer review, prior to final printing. These proceedings should not be used as the only current reference on the topic, but are meant to serve as one resource to fill source immediate needs. No textual editing of the questions and answers were performed, and as these comments were spoken, may tend to read strangely. It is felt that much of the value of topical meetings comes from exchanges at the end of each presentation, and hence worthy of inclusion. These proceedings, and the symposium it reports, were made possible by the support of numerous people. Initially, one must recognize the authors, without whose cooperation, this would only appear as a summary. Principally, however, the Southern California Chapters Board of Directors and Officers made them possible because of the conceptualization of the meeting and selection of the very able General Chair and Committee Chair. Members of the chapter that served the committees performed superbly to the person, to the end, truly a fine team effort. It has been a privilege to serve as the anchorman in wrapping up the second, highly successful symposium hosted by the Southern California Chapter in less than a decade. William W.

Wadman III Southern California Chapter President OPENING OF THE SYMPOSIUM JANET TRUNZO, GENERAL CHAIR I'd first like to welcome everyone to San Diego, and especially to the Health Physics Society 11th Midyear Topical Symposium. As you know the topic of this Symposium is Radiation Instrumentation and I think there is a fine program ahead of you for the next 2% days. Before I make a few comments abnut the program, I'd like to discuss a few of the social activities that we have planned for the next few days. This evening we have the annual night out and this is a Luau, a California-type of Luau, for those of you from Hawaii. But I'd like to explain what fun this is going to be. The costs of the tickets include drinks, a complete buffet and entertainment in the form of a show and continuous music from 7 to 11 p.m, the whole evening's en- tertainment with food and beverages. So I hope that you can all come. Also the spouse activity scheduled for today is the Tijuana tour. I believe it's going to be leaving around 9ish. Tomorrow we have a harbor cruise. Both of them are very entertaining and enjoyable. To- morrow at noon is the luncheon and we will have a speaker at that lun- cheon and everyone has a ticket for that with registration. There are a few changes in the program that I think you should be aware of. Today, Technical Session B, Environmental Monitoring, a paper was not listed that will be given at 11:40 a.m. The name of the paper is "Radiation Measuring Instrumentation for the Uranium Mining Industry" by Robert Gray. Two papers have been cancelled: Tuesday, January 17, Session C, Radiation Detectors, 1:50 p.m., "The Low Tem- perature Scintillation Properties of Bismuth Germanate and its Appli- cation to High Energy Gamma Radiation Imaging Devices". Next page, Session D, one paper cancelled, 4:40 p.m., "A Radiation Detection System for Vehicular Traffic Monitoring". All papers given today will be of 20 minutes duration: 15 minutes for the presentation, 5 minutes for questions, except one session on Portable Instrumen- tation, the papers will be of 15 minutes duration.

  • Personnel Monitoring
    RADIOLOGICAL MONITORING, METHOD, INSTRUMENTATION AND TECHNIQUES: PERSONNEL MONITORING Agensi Nuklear Malaysia Contents Introduction Objective of Personnel Monitoring Personnel Monitoring Instrument for External Radiation Personnel Monitoring Instrument for Internal radiation Calibration and Quality Control Introduction Atomic Energy Licensing Regulations (BSS) 2010 (Act 304) require monitoring to be carried out on all personnel who work in controlled areas (and selectively in supervised areas). Occupational exposure can be delivered to personnel either by sources outside the body in the form of external radiation or by intake of radioactive contaminants. Atomic Energy Licensing Regulations (BSS) 2010 (Act 304) require the radiation exposures both from external and internal sources be evaluated to represent an individual dose in a year. A devices that is accepted by the AELB are required by all personnel to measure the radiation dose received while working with radiation sources or working in classified areas. Objective of Personnel Monitoring To provide information on radiation dose received by workers. To observe the trends of exposure histories of individuals or groups of workers in order to assess the need for improved standards of radiation protection. To provide information in the event of accidental over exposure. To provide information about the condition of radiation level at workplace. To improve the workers attitudes toward radiation protection in order to reduce future exposures as a results of information given to them. To demonstrate the adequacy of supervision, training and engineering standards. To provide a record of information which may be needed for legal or epidemiological purposes. Personal monitoring External monitoring Internal monitoring (the measurement of dose due to (the measurement of dose due to sources outside the body) sources inside the body) Whole body Partial body monitoring (extremity) 1.

  • Chem 481 Lecture Material 3/13/09
    Chem 481 Lecture Material 3/13/09 Radiation Detection and Measurement When radiation interacts with matter electronic excitation and ionization occur. When de-excitation results in the emission of photons these can be detected by suitable light- sensitive devices. When charge carriers (ion pairs, electron/hole pairs) are produced these can be collected to generate an electrical signal. The dead time of a detector is the length of time between the formation of an output signal (pulse) and when the detector conditions are able to produce another output signal (see figure below). Initially this second output is insufficient in size to be recognized by the counting electronics (less than the discriminator level). The resolving time is the interval between the initial pulse and the formation of a detectable pulse (see figure below). The recovery time is the interval between two full-size pulses. Events that occur during the resolving time will not be recorded and are known as coincidence losses. Gas Ionization Detectors Imagine a gas-filled container with 2 electrodes of opposite charge (see figure below). As radiation enters the gas filling and ionizes the gas (creates primary cation-electron pairs), the cations will drift toward the negatively-charged electrode and the electrons Radiation Detection and Measurement 3/13/09 page 2 will be collected at the positive anode resulting in a current that can be measured. Some cations and electrons may recombine. As the electric potential across the electrodes is increased a voltage is reached where the electrode attraction is greater than the attraction between cations and electrons and all primary ion pairs are collected.

  • Dosimeter 1 Dosimeter
    Dosimeter 1 Dosimeter Dosimeters measure an individual's or an object's[1] exposure to something in the environment — particularly to a hazard inflicting cumulative impact over long periods of time, or over a lifetime. This article concentrates on the radiation dosimeter, which measures Fiber dosimeter exposure to ionizing radiation, but other dosimeters also exist, such as sound dosimeters, ultraviolet dosimeters, and electromagnetic field dosimeters. Ionizing radiation, such as X-rays, alpha rays, beta rays, and gamma rays, remains undetectable by the senses, and the damage it causes to the body is cumulative, related to the total dose received. Therefore, workers who are exposed to radiation, such as radiographers, nuclear power plant workers, doctors using radiotherapy, workers in laboratories using radionuclides, and some HAZMAT teams are required to wear dosimeters so their employers can keep a record of their exposure, to verify that it is below legally prescribed limits. Common types of wearable dosimeters for ionizing radiation include: • Quartz fiber dosimeter • Film badge dosimeter • Thermoluminescent dosimeter • Solid state (MOSFET or silicon diode) dosimeter The quartz fiber dosimeters have to be prepared, usually daily, with a positive charge from either a hand-wound or battery-powered charging unit. As the dosimeter is affected by nuclear radiation the charge leaks away causing the fiber indicator to rise up the graduated scale. Factories prepare film-badge dosimeters for one-time use. The level of radiation absorption is indicated by a change of color on the film badge's surface, which is compared to an indicator chart. Manufacturing processes that treat products with ionizing radiation, such as food irradiation, use dosimeters to calibrate doses.
