SUMMARY
The initial power calculated for a Plutonium-238 powered pacemaker, using 180 mg of the isotope with a half-life of 90 years and an alpha particle energy of 5.10 MeV, is derived from the decay energy conversion. Assuming 100% efficiency, the power output can be calculated using the formula P = W/t, where W is the total energy released from the decays occurring in the first second. The discussion clarifies that "initial" refers to the power output before any decay has occurred.
