Power output of nuclear battery

  1. Apr 20, 2008 #1
    [SOLVED] Power output of nuclear battery

    1. The problem statement, all variables and given/known data

    An alpha emitter 210Po is used in a nuclear battery. The kinetic energy of the emitted alpha particle is converted into electrical energy at 5% efficiency.

    a) determine the initial power output (W) of the battery if it contains 200g of 210Po.
    b) determine the power output (W) of the battery in part a after 1 year of operation.


    3. The attempt at a solution

    I have worked out the following:
    alpha particle= 2protons, 2 neutrons, mass= 4.031882u=3.75567GeV= ~ 6.0166x10^-10 Joules. T1/2= 138.376days

    I am having difficulties applying this data I have worked out into energy from 200g of 210Po. Can some one enlighten me and put me on the right track? thanks
