(acronym for As Low As Reasonably Achievable) making every reasonable effort to maintain exposures to radiation as far below the dose limits as is practical consistent with the purpose for which the licensed activity is undertaken, taking into account the state of technology, the economics of improvements in relation to state of technology, the economics of improvements in relation to benefits to the public health and safety, and other societal and socioeconomic considerations, and in relation to utilization of nuclear energy and licensed materials in the public interest.
Refers to a substance, that measures must be taken to keep a worker's exposure to a level as low as is reasonably achievable.
As low as reasonably achievable. basic radiation protection concept to reduce doses to the lowest possible levels through the proper use of time, distance and shielding.
"As Low As is Reasonably Achievable," which is the approach to radiation protection to manage and control exposures (both individual and collective) to the work force and to the general public to as low as is reasonable, taking into account social, technical, economic, practical, and public policy considerations. As used in this part, ALARA is not a dose limit but a process which has the objective of attaining doses as far below the applicable limits of this part as is reasonably achievable.
As Low As Reasonably Achievable. Principle used in radation protection relating to doses to people which should always be as low as possible, after all 'reasonable' methods of reduction have been applied.
As low as reasonably achievable. An approach to radiation protection designed to manage and control individual and collective radiation doses to the workforce and the general public and to ensure that exposure is kept to the lowest level reasonably achievable. The ALARA approach considers aspects of the social, technical, economic, practical, and public impacts.
a principle which is used to reduce unnecessary, potentially hazardous exposure to individuals, by keeping doses As Low As Reasonably Achievable. As shown throughout this guideline, application of the ALARA principle to diagnostic ultrasound differs from its common usage in diagnostic X-ray imaging where it is assumed that there is no threshold exposure. In the use of diagnostic ultrasound, there are three ranges of exposure, i.e., combinations of Thermal or Mechanical Indices and dwell time, that need to be considered. At exposures that are clearly below the thresholds for health effects, further reduction of exposure is not justified, whether it is via reductions in dwell time or acoustic output. There can also be exposures that are or may be above thresholds for health effects. In these cases, ALARA refers to using the lowest value of potentially hazardous exposure, i.e. combination of acoustic output and dwell time, needed to achieve the required diagnostic information.
As low as reasonably achievable (practicable) In GBR regulations relating to worker exposure In USA goal of risk management (USNRC regulations)
The approach to hazardous agent (e.g., radiation, chemical, physical, or carcinogen) protection to manage and control exposures (both individual and collective) to the work force, the general public, and the environment to as low as is reasonable, taking into account social, technical, economic, practical, and public policy considerations. ALARA is not a dose limit but a process that has the objective of attaining doses as far below the applicable limits as is reasonably achievable.
ALARA stands for "as low as reasonably achievable." Taking into account the state of technology, we shall make every reasonable effort to maintain exposures to radiation far below the federal and state dose limits. ALARA is the core of the radiation protection program.
As low as reasonably achievable; a concept meaning that the design and use of nuclear facilities should be such as to ensure that radiation exposures should be ALARA, economic and social factors being taken into account
As low as reasonably achievable, a radiation safety principle, social and economic factors considered.
Since exposure to radiation always carries some risk, the exposure should be kept "As Low As Reasonably Achievable", as defined by 10 CFR 20.
As Low As reasonably Achievable. refers to maintaining offsite radioactive releases and occupational radiation exposures as low as achievable in a reasonable, cost-effective manner.
As Low As Reasonably Achievable (Typically in reference to exposure to hazardous materials or hazards such as radiation)
Acronym for "as low as reasonably achievable." The Nuclear Regulatory Commission defines ALARA as making every reasonable effort to maintain radiation exposures to as far below the dose limits as is practical considering the state of technology, the economics of improvements in relation to the state of technology, the economics of improvements in relation to the benefits to the public health and safety, and other societal and socioeconomic considerations, and in relation to utilization of nuclear energy and license materials in the public interest.
The guiding principle behind radiation protection is that radiation exposures should be kept "As Low As Reasonably Achievable (ALARA)," economic and social factors being taken into account. This common sense approach means that radiation doses for both workers and the public are typically kept lower than their regulatory limits. back to
As Low As Reasonably Achievable, or keeping radiation emissions and exposures to levels set as far below regulatory limits as is reasonably possible in order to protect public health and the environment.
A philosophy and system of dose limitation based on keeping doses As Low As Reasonably Achievable, economic and social factors being taken into account.
As Low As Reasonably Achievable, economic and social factors being taken into account. This is the optimisation principle of radiation protection.
ALARA is an acronym for an important principle in radiation protection and stands for "As Low As Reasonably Achievable". The aim is to minimize the risk of radioactive exposure. This compromise is well illustrated in radiology.
