Background Comprehensive assessments of the frequency and associated doses from radiologic nuclear medicine procedures are rarely conducted. The use these population-based radiation dose increased remarkably 1980 to 2006. Purpose To determine change in per capita exposure United States 2006 2016. Materials Methods U.S. National Council on Radiation Protection Measurements conducted a retrospective assessment for 2016 compared results previously published data year Effective values were...
Epidemiologic studies of radiation-exposed populations form the basis for human safety standards. They also help shape public health policy and evidence-based practices by identifying quantifying risks exposure in defined populations. For more than a century, epidemiologists have studied consequences radiation exposures, yet effects low levels delivered at low-dose rate remain equivocal.
Abstract In the event of a nuclear explosion in an urban environment, contaminated persons may be directed to Community Reception Centers (CRC) and/or public shelters. This paper is companion document previous that addresses inhalation hazard workers at CRC from resuspension fallout evacuees. To limit evacuees must screened prevent severely entering CRC. The suggested screening level 10,000 dpm cm −2 and rapid methods arriving are presented. Practical advice provided on can used...
The goal of this study was to investigate the willingness Medical Reserve Corps (MRC) volunteers participate in public health emergency–related activities by assessing their attitudes and beliefs. MRC responded an online survey organized around Extended Parallel Process Model (EPPM). Respondents reported agreement with attitude/belief statements representing perceived threat, efficacy, personal/organizational preparedness 4 scenarios: a weather-related disaster, pandemic influenza emergency,...
One of the key issues in aftermath an exploded radiological dispersal device from a terrorist event is that contaminated victim and concern among healthcare providers for harmful exposures they may receive treating patients, especially if patient has not been thoroughly decontaminated. This critically important mass casualties nuclear or incident because essential rapidity acute medical decisions those who have life- limb-threatening injuries treatment unduly delayed by decontamination...
This article summarizes major points from a newly released guide published online by the Office of Assistant Secretary for Preparedness and Response (ASPR). The reviews basic principles about radiation its measurement, short-term long-term effects radiation, medical countermeasures as well essential information how to prepare respond nuclear detonation. A link is provided manual itself, which in turn heavily referenced readers who wish have more detail.
ABSTRACTOne of the biggest medical challenges after detonation a nuclear device will be implementing strategy to assess severity radiation exposure among survivors and triage them appropriately. Those found at significant risk for injury can prioritized receive potentially lifesaving myeloid cytokines evacuated other communities with intact health care infrastructure prior onset severe complications bone marrow suppression. Currently, most efficient accessible method is use sequential...
Following a radiological or nuclear emergency, first responders and the public may become internally contaminated with radioactive materials, as demonstrated during Goiânia, Chernobyl Fukushima accidents. Timely monitoring of affected populations for potential internal contamination, assessment radiation dose provision necessary medical treatment are required to minimize health risks from contamination. This paper summarizes guidelines tools that have been developed, identifies gaps...
On 11 March 2011, northern Japan was struck by first a magnitude 9.0 earthquake off the eastern coast and then an ensuing tsunami. At Fukushima Dai-ichi Nuclear Power Plant (NPP), these twin disasters initiated cascade of events that led to radionuclide releases. Radioactive material from subsequently transported locations around globe, including U.S. The levels radioactive arrived in were never large enough cause health effects, but presence this environment require response public...
The detonation of a radiological dispersion device or other incidents could result in the radioactive materials and intakes radionuclides by affected individuals. Transportable radiation monitoring instruments be used to measure photon from body for triaging individuals assigning priorities their bioassay samples further assessments. Computer simulations experimental measurements are required these assessing radionuclides. Count rates calibrated sources 60Co, 137Cs, 241Am were measured on...
A growing body of audience research reveals medical personnel in hospitals are unprepared for a large-scale radiological emergency such as terrorist event involving radioactive or nuclear materials. Also, lack basic understanding radiation principles, well diagnostic and treatment guidelines exposure. Clinicians have indicated that they sufficient training on preparedness; potentially unwilling to treat patients if those perceived be radiologically contaminated; major concerns about public...

After a radiological dispersal device (RDD) event, people could become internally contaminated by inhaling dispersed radioactive particles. A rapid method to screen individuals who are is desirable. Such initial screening can help in prompt identification of those highly and prioritising for further more definitive evaluation such as laboratory testing. The use handheld plastic scintillators rapidly exposed an RDD with gamma-emitting radionuclides was investigated this study. Monte Carlo...

Transportable radiation monitoring instruments be used to measure from gamma-emitting the body for triaging individuals assigning priorities their bioassay samples vitro assessments. present study derived sets calibration factors four instruments: Ludlum Model 44-2 gamma scintillator, survey meter containing 2.54 ×...
Following a radioactive dispersal device (RDD) incident, it may be necessary to evaluate the internal contamination levels of large number potentially affected individuals determine if immediate medical follow-up is necessary. Since current laboratory capacity screen for limited, rapid field screening methods can useful in prioritising individuals. This study evaluated suitability radiation portal monitor such screening.
