The approximate number of decays this represent is
Explanation:
From the question we are told that
The amount of Radiation received by an average american is
The source of the radiation is
Generally
Therefore
Also
Therefore
An Average american weighs 88.7 kg
The total energy received is mathematically evaluated as
Cross-multiplying and making x the subject
Therefore the total energy deposited is
The approximate number of decays this represent is mathematically evaluated as
N =
Where n is the approximate number of decay
Substituting values
