A1-mci source of^60 co is placed in the center of a cylindrical water-filled tank with an inside diameter of 20 cm and depth of 100 cm. the tank is made of iron with a wall thickness of 1 cm. what is the uncollided flux density at the outer surface of the tank nearest the source?

To solve this problem we need the concepts of Energy fluency and Intensity from chemical elements.

The energy fluency is given by the equation

Where

The energy fluency

c = Activity of the source

r = distance

E = electric field

In the other hand we have the equation for current in materials, which is given by

Then replacing our values we have that

We can conclude in this part that 1.3*10^7Bq is the activity coming out of the cylinder.

Now the energy fluency would be,

The  uncollided flux density at the outer surface of the tank nearest the source is
