Question

The isotope of Nickel, ⁶⁶Ni decays by β emission, has a half-life of 2.3 days. and the β particles have an average energy of 65 keV. A source consisting of this isotope has an initial number of atoms N₀ = 5 x 10²⁰ atoms.

What is the power per unit area initially deposited by this source in a small target placed at 1m distance from the source?

Select one:

a. 1.45 W/m²

b. 7.6 MW/m²

c. 4.5 kW/m²
