Question
The dosage of technetium-99m for a lung scan is 20. Ci/kg of body mass. How many millicuries of technetium-99m should be given to a 60 kg person? (Recall that 1 mCi = 1000 Ci.)
Express the radiation dose in millicuries to two significant figures.

To calculate the dosage of technetium-99m for a 60 kg person, we first convert the body mass from kg to Ci.
Body mass in Ci = (20 Ci/kg) * (60 kg) = 1200 Ci
Since 1 mCi = 1000 Ci, we can convert the dosage to millicuries.
Dosage in millicuries = 1200 Ci * (1 mCi/1000 Ci) = 1.2 mCi
Therefore, the 60 kg person should be given 1.2 millicuries of technetium-99m.
Body mass in Ci = (20 Ci/kg) * (60 kg) = 1200 Ci
Since 1 mCi = 1000 Ci, we can convert the dosage to millicuries.
Dosage in millicuries = 1200 Ci * (1 mCi/1000 Ci) = 1.2 mCi
Therefore, the 60 kg person should be given 1.2 millicuries of technetium-99m.
