Final answer:
The dose in rem to the tumor from a 1.50 kg tumor exposed to y rays can be calculated using the given information. Consult with a healthcare professional to determine if the dose is consistent with therapeutic doses.
Step-by-step explanation:
For a 1.50 kg tumor exposed to y rays from a 5000-Ci Co transillumination unit for 32.0 s, the dose in rem to the tumor can be calculated as follows:
- Calculate the number of y rays striking the patient: 5000 Ci x 1.00% (collimated rays) = 50 Ci
- Calculate the number of rays absorbed by the tumor: 50 Ci x 20.0% = 10 Ci
- Convert the absorbed dose from Ci to rem: 10 Ci x 2400 rem/Ci = 24000 rem
Therefore, the dose in rem to the tumor is 24000 rem.
Whether this dose is consistent with stated therapeutic doses depends on the specific requirements and goals of the treatment. It is best to consult with a healthcare professional or radiation oncologist for a comprehensive evaluation.
