Polonium-218 is an alpha emitter with a half-life of 3.0 minutes.

**)If a sample contains 55 mg of Po−218 (atomic mass = 218.008965 amu), how many alpha emissions would occur in 27.0 minutes?

**)If the polonium were ingested by a person, to what dose of radiation (in Ci) would the person be exposed? (I need correct answer for this please)

Polonium , is a radioactive element ,

the element decays as follows ,

Half life of a reaction is the time at which the concentration of the reactant reduced to half.

According to definition,

A_t = (1/2)*A₀

Applying in the integrated rate law as:
