Homework #5:

1.  If you have a parallelepiped volumetric isotropic source with a strength of 100 particles/cc/sec and W=20 cm, L=10 cm, H=200 cm:
a. Find the equivalent surface source if the analyst judges that L is insignificant.

b. Find the equivalent line source if the analyst judges that W is also insignificant; and

c. Find the equivalent point source if the analyst judges that H is insignificant as well.

For each of these be sure the source size, placement and strength (in appropriate units) is specified.

2. Use the Appendix H data to give me the appropriate source description for an isotropic 1 microCurie Co-60 point source that is 10 years old.  Express the answer as a distribution in direction and energy.  (It will be the sum of two terms containing a SINGLE Dirac delta each.)
