Radiation and litigation : analyses of the ALARA principle and low dose radiation in the courts, and the future of radiation in court cases
… radiation doses in the work place is the ALARA principle which stands for "as low as reasonably achievable". Within the phrase, "reasonably achievable" there is an implied element of subjectivity. Because "reasonably achievable" can vary in meaning for different people, this paper will …

Spatial Coherence-Based Adaptive Acoustic Output Selection for Diagnostic Ultrasound
… societies advise users to observe the ALARA (as low as reasonably achievable) principle with regard to acoustic exposure, but several studies have shown that the majority of ultrasound users do not monitor safety indices. To address this discrepancy, an adaptive ultrasound method has …

Facility-Specific Radiation Exposure Risks and Their Implications for Radiation Workers at Department of Energy Laboratories
… setting where As Low As Reasonably Achievable (ALARA) practices are mandated or used. The evaluation is performed by developing a hypothesis-test-based procedure for evaluating the homogeneity of various epidemiological cohorts, and thus the appropriateness of the application of aggregate …

A generic methodology for the three dimensional display of radiation fields
… training and As Low As Reasonably Achievable (ALARA) radiation dose planning. This thesis describes a novel technique for the creation of 3d visualizations of radiation fields. The methodology is developed and shown to be effective within the Google SketchUp Computer Aided Design (CAD) software …

Co-production of Science and Regulation: Radiation Health and the Linear No-Threshold Model
… de minimis exposure to the general public, the ALARA principle emerged as an important ordering instrument even before the linear no-threshold model had gained wide support. Even before ALARA became the law, it had taken hold in a manner that allowed the nuclear industry to rationalize its …

Characterization of Radiation Fields and Dose Assessment From Fuels Manufacturing For Advanced Fuel Cycles
… radiation dose as low as reasonable achievable (ALARA), dose rates were calculated for various fuel compositions for light water reactors (LWR) and fast reactor (FR) mixed oxide (MOX) fuels with and without MA. The impact of varying the separation efficiency of americium (Am) and curium (Cm) was …

Feasibility Study of Low Dose Chest CT for Initial Evaluation of Blunt Chest Trauma Patient
… trauma evaluation. Therefore, according to the ALARA (as low as reasonable achievable) principle, radiation dose adjustment in the patients with blunt chest trauma is inevitable. We aimed to evaluate the diagnostic performance and inter-observer consistency of low-dose chest CT (LDCT) in the …

Estudio prospectivo comparativo de dos métodos de cálculo individual de la actividad de 131I en el tratamiento del hipertiroidismo.
… básicos de radioprotección (como el principio ALARA, As Low As Reasonably Achievable) aconsejan el empleo de "dosis calculadas" (mediante cálculos dosimétricos de mayor o menor complejidad). Los factores que deberían contemplarse al menos serían la captación tiroidea de 131I, y su vida media en …

Ein effektiver und verlässlicher Ansatz zur Reduktion der Strahlenexposition des medizinischen Personals im Kontext der Radiojodtherapie
Die Validierung der Aktivität der Jod-131-Kapseln vor der Radiojodtherapie ist gesetzlich vorgeschrieben. Die Anwendung des dargestellten alternativen Messverfahrens führt zu einer erheblichen Reduktion der Strahlenbelastung des medizinischen Personals und insbesondere der Hände. Es ermöglicht eine …
