Suppose that a scientist is going to do an experiment using αparticles from the radioactive source containing one milligram 210Po. This is a very intense source producing 1.65 x 1012 decays/s (=1.65 x 1012 Bq). The αparticles go off in random directions, but only the ones inthe direction of your target may be used for the experiment. Suppose that the target being irradiated is 10 cm from the source. What is the flux, Φ,of αparticles hitting the target?A useful fact is that the area A of a sphere isA=4πr2.

a and b sometimes have a positive value
