The dosage of technetium99m for a lung scan is 20 microCikg

The dosage of technetium-99m for a lung scan is 20. microCi/kg of body mass. How many millicuries of technetium-99m are needed for a 50.0 kg patient? 0.0025 mCi 0.4 mCi 1.0 mCi 2.5 mCi 1000 mCi 2500 mCi 1.0 times 10^6 mCi

Solution

Technetium 99m is the nuclear isomer of technetium which is used in millions of medical Diagnostic procedures annually and is the most commonly used medical radioisotope

If 20 microCI technetium is used for per kg body mass of a patient for diagnosing them

Then according to 50 kg patient the amount required will be 50 into 20 micro CI that comes out to be approximately 1000 microCI option E
