Program-name Package-ID Status BRIGITTE NEA-0390/01 Tested

Machines used: Package-ID Orig.Computer Test Computer NEA-0390/01 IBM 370 series IBM 370 series

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.

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.

6. TYPICAL RUNNING TIME - Under one minute for IBM 360/75.
