3. DESCRIPTION OF PROBLEM OR FUNCTION

The REBEL-3 adjoint Monte Carlo code calculates the doses in the whole body, in the testicles, ovaries, red or yellow marrow, or in the lungs of an inhomogeneous phantom standing in a dwelling room. In addition it can calculate also the kerma rate in free air. Separate results are given for the three most important gamma emitters (K-40, U-Ra-chain and Th- chain) of the usual wall materials. The dimensions of the room, the thicknesses and the material composition of the walls as well as any number of neighbouring rooms can be specified in the input.
Basic geometrical approximations:
-  the room is a rectangular block
-  the parallel walls have equal thicknesses
-  the walls are homogeneous
-  there are no doors or windows

Basic physical approximations:
- energies of the gammas emitted during the decay of the U-Ra and  Th series are represented by 24 and 20 lines, respectively - the Compton scattering is described by the Klein-Nishina formula    and coherent scattering is not taken into account

4. METHOD OF SOLUTION:  Adjoint Monte Carlo.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

(Besides those listed in 3.):
- if the spectrum of the photons is calculated: maximum number of    energy groups:  20
- maximum 10 different specific activities (i.e. activity per unit    mass of the wall material) can be specified for one run.

6. TYPICAL RUNNING TIME

It depends strongly on the accuracy needed. For standard deviations of 2-3%, about 10-20 minutes are needed on the R-40.  Most probably less on other computers.

11. MACHINE REQUIREMENTS

-  high speed memory:  100 K bytes
-  card reader
-  line printer
-  clock for the measurement of the CPU time, in our version:
subroutine TIMEL(T) gives in T the time in seconds (8 byte real)  elapsed from the last call of TIMEL or TIMSET. Time is set to    zero by subroutine TIMSET at the beginning.
IAEA0846/01
To execute the test case included in this package on an IBM 3081 computer, 240K bytes of main storage are required.
