The fuel element 4 within the container 14 is drawn into a cylindrical column 17 by a lifting device. The column 17 is enclosed by a cylinder 18 of BeO which emits neutrons when acted upon by high-energy -rays. Four collimators 19 disposed in the cylinder 18 guide neutrons from the ...
Step 3: Calculate the Number of Neutrons for Each ElementThe number of neutrons (N) can be calculated using the formula:N=A−Zwhere A is the atomic mass number and Z is the atomic number. 1. For Argon (Ar): - A = 40, Z = 18 - N = 40 - 18 = 22 2. For Calcium (Ca):...
