Which of the following is an example of an ALARA (As Low As Reasonably Achievable) practice?

Question

Question

Answer 1

Correct Answer: Both b and c

Rationale:

ALARA (As Low As Reasonably Achievable) is a safety principle designed to minimize radiation exposure and its effects, focusing on reducing doses to the lowest possible level while considering economic and practical factors.
Wearing a lead apron during procedures (Option 2) is a key practice in ALARA. Lead aprons are effective in shielding the body from harmful radiation, thus reducing the dose absorbed by the person wearing it.
Using non-ionizing radiation whenever possible (Option 3) aligns with ALARA principles because non-ionizing radiation does not carry enough energy to ionize atoms or molecules, thus posing less risk of biological damage compared to ionizing radiation.

Explanation of Other Options:

Using the highest possible kVp

Rationale: Using the highest possible kVp (kilovolt peak) is not an ALARA practice. High kVp settings increase the energy of the X-rays and potentially the radiation dose to the patient. While higher kVp can reduce the dose by reducing the quantity of radiation required, it must be balanced carefully to not increase exposure unnecessarily.

Wearing a lead apron during procedures

Rationale: Wearing a lead apron is a protective measure to minimize exposure to ionizing radiation. Lead aprons effectively block or attenuate the radiation, thus protecting healthcare workers from its harmful effects.

Using non-ionizing radiation whenever possible

Rationale: Non-ionizing radiation, such as ultrasound or MRI, is preferred when suitable because it does not have enough energy to remove tightly bound electrons or ionize atoms. This minimizes the risk of radiation-induced damage.

Both b and c

Rationale: Combining the use of protective measures like lead aprons and opting for non-ionizing radiation techniques whenever possible is in line with ALARA principles, aiming to reduce radiation exposure to the lowest possible level.

Conclusion:

The ALARA principle focuses on minimizing radiation exposure through practical and effective measures. Wearing lead aprons and using non-ionizing radiation are two key practices that help achieve this goal, ensuring safety and reducing potential risks associated with ionizing radiation.
