Radioactive Iodine-125 and Palladium-103 Decay by X-Ray Emission and Are ×\times

Question 105

Multiple Choice

Radioactive iodine-125 and palladium-103 decay by X-ray emission and are used in brachytherapy to treat cancer. Consider two patients, one being treated with I-125 and the other with Pd-103. Both receive a total dose of 145 Gy delivered over 10 months. What can be concluded from the data in the table about these treatments? Note: 1 keV = 1.602 ×\times 10-16 J.
