Given information
Every decay of 
emits a 
ray of 
radiation
To get the dosage of radiation 
in curie.
Step-by-step explanation
Step 1.
Information about the task:
. 
-Mass.
. 
Ci-Activity.
. 
-Efficiency. Requested data: 
, the rate of energy.
, the rate of energy.
decay 
to express as the decay rate We then notice that energy is deposited in the body, thus we calculate 
as the rate of energy deposition.
as the decay rate We then notice that energy is deposited in the body, thus we calculate as the rate of energy deposition. 
Finally, noting that 
, we can divide 
with , and convert to
