58. . Radiation treatment of prostate cancer. In many cases, BIO prostate cancer is treated by implanting 60 to 100 small seeds of radioactive material into the tumor. The energy released from the decays kills the tumor. One isotope that is used (there are others) is palladium (10Pd), with a half-life of 17 days. If a typical grain contains 0.250 g of 10Pd, (a) what is its initial activity rate in Bq, and (b) what is the rate 68 days later?

58. . Radiation treatment of prostate cancer. In many cases,
BIO prostate cancer is treated by implanting 60 to 100 small seeds
of radioactive material into the tumor. The energy released
from the decays kills the tumor. One isotope that is used (there
are others) is palladium (10°Pd), with a half-life of 17 days. If
a typical grain contains 0.250 g of 10°Pd, (a) what is its initial
activity rate in Bq, and (b) what is the rate 68 days later?
