DHA Radiotherapy Technician Sample Test

You perform an imaging procedure of a patient’s hand. The patient is sitting erect and is seated with his hand on the end of the table. Which of the following is used to protect the patient from radiation?

Correct Answer:
a gonadal shield
in medical imaging, particularly procedures involving x-rays, protecting patients from unnecessary radiation exposure is crucial. one of the primary methods to achieve this is through the use of protective shields, with the gonadal shield being one of the most commonly used types.

the gonadal shield is specifically designed to protect the reproductive organs, which are particularly sensitive to radiation. this is important because radiation can cause damage at the cellular level, potentially leading to mutations and increasing the risk of cancer and genetic defects. the reproductive organs are considered critical organs when it comes to radiation protection because any damage can not only affect the individual but also potentially affect future generations.

in the scenario described, where a patient undergoes an imaging procedure of the hand, you might wonder why a gonadal shield would be necessary since the hand is far from the gonads. the rationale lies in the principle of "as low as reasonably achievable" (alara) in radiation protection. alara is a safety principle designed to minimize radiation doses and releases of radioactive materials by employing all reasonable methods.

even though the primary beam of the x-ray might be directed at the hand, scatter radiation can travel to other parts of the body. scatter radiation refers to radiation that is deflected from its path as it interacts with matter, in this case, parts of the patient's body. this scattered radiation can inadvertently expose other parts of the body to radiation, including the reproductive organs.

the use of a gonadal shield in such procedures, even though the target area is the hand, is a precautionary measure to ensure that scattered radiation does not reach and harm the reproductive organs. the shield is typically made of lead or similar radiation-absorbing materials and is placed over the patient’s pelvic area to protect the gonads.

thus, the use of a gonadal shield not only adheres to the alara principle but also ensures that the patient’s health and reproductive capabilities are not compromised due to the necessary medical imaging of a different body part. this approach underlines the comprehensive safety measures undertaken in radiological practices to safeguard patient health during diagnostic procedures.
