| Abstract: | A non-uniform line
source has a continuous spatial variation of activity along its length. It may
not be possible to divide such a source into smaller sources of uniform
activity. Such situation may arise in case of a pipe carrying radioactivity in
liquid form. A Mathematica based code was developed for calculating uncollided
flux due to a line source having Gaussian distribution of activity and also a
line source with uniform activity placed in air or a non-attenuating medium for
comparison. Uncollided flux due to a uniform cylindrical source behind a slab
shield was also calculated by replacing it with an equivalent uniform line
source using another Mathematica based code and it’s output was compared to a
point kernel method based code GUI2QAD-3D. Both the codes employ numerical
integration. |
