What does ALARA stand for in radiation safety?

• A. As low as reasonably attainable
• B. As low as reasonably achievable
• C. As low as radiologically acceptable
• D. As low as regulated allowable

Answer: (B)

ALARA stands for "As Low As Reasonably Achievable." This principle is central to radiation safety and is designed to minimize radiation exposure to both patients and healthcare workers. The concept emphasizes that all radiation exposure should be reduced to the lowest possible level while still achieving the necessary diagnostic or therapeutic objectives. This involves taking into account economic considerations and feasibility when making decisions about radiation doses.

The focus on reasonable achievement underscores the balance between keeping exposure low and ensuring that the benefits of using radiation outweigh the risks. This is a critical aspect of practice in medical imaging and intervention to promote both safety and effective patient care.

Other options do not accurately reflect the established terminology within radiation safety standards. The option referring to "attainable" implies a potential level that may not relate to practical methods in radiological practice, while terms like "acceptable" and "regulated allowable" do not reflect the proactive and ethically driven nature of the ALARA principle. The emphasis on "achievable" captures the iterative process of continually improving safety measures without compromising the quality of care.
