Final answer:
True, recording the radiation dose for each radiation-producing modality is necessary for patient safety and the assessment of the risk versus benefit of medical procedures involving radiation.
Step-by-step explanation:
The statement is true; there is a need for each radiation-producing modality to record patient radiation dose. Accurate dosimetry is crucial for ensuring patient safety and for evaluating the risks versus the benefits of procedures involving radiation. Diagnostic doses are tailored to be as low as reasonably achievable while still providing the necessary diagnostic information. For example, a CT scan may expose a patient to about 10 mSv of radiation, affecting only the tissue imaged. On the other hand, therapeutic exposure, like in cancer treatment using Cobalt-60, involves higher doses that are carefully calculated to maximize treatment efficacy while minimizing harm to surrounding healthy tissues.
Medical personnel use devices such as film badges or dosimeters to measure radiation exposure in rems or sieverts. Additionally, with the development of new techniques and more sensitive films, the doses from diagnostic procedures like chest x-rays or radiopharmaceuticals have been further reduced over time. In any case, the provided radiation dose is justified by the significant benefit gained from accurate diagnosis or effective treatment of diseases.
