Final answer:
The statement is true; the molybdenum-99/technetium-99m generator allows for weekly delivery and daily access to the technetium-99m isotope due to the longer half-life of Mo-99 compared to Tc-99m. This system is essential for nuclear medical imaging in healthcare.
Step-by-step explanation:
The statement that 'The molybdenum generator allows once-weekly delivery of a generator with daily access to technetium' is true. The molybdenum-99/technetium-99m generator is a system used primarily in hospitals for the on-site generation of technetium-99m (Tc-99m), a radioisotope used in nuclear medical imaging. Molybdenum-99 has a half-life of 66 hours, which permits transportation to hospitals without significant decay. In the hospital, Mo-99 decays to Tc-99m, which has a short half-life of 6.01 hours. Through a process called elution, or 'milking,' Tc-99m is extracted daily from the generator to be used in various diagnostic procedures. This system allows for the efficient and timely provision of Tc-99m without the need for frequent deliveries, reducing costs and waste while ensuring that healthcare facilities have consistent access to the isotope for patient care.
