3. NATURE OF PHYSICAL PROBLEM SOLVED

Calculation of dose rate, heat sources or energy flux. The sources are self-absorbing radioactive rods. The shielding consists of blocks of which the cross section can be defined.
top ]
4. METHOD OF SOLUTION

Exponential attenuation and build-up factor between source points and detector points. Source integration with error estimate. Automatic or controlled build-up with monitor print-out.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Number of energy points, regions, detector points, abscissa points of the rod, vertical position of the rod, are all limited to ten. The maximum total number of vertical steps is 124.
