Re: Microshield

Grove Engineering, in Rockville, MD supplies Microshield.  I have version
4.21, which is a great improvement.  Two especially helpful upgrades:  the
graphic of the source and shielding changes to keep the scale of the
dimensions you input, and the program includes equilibrium radionuclides;
e.g., older versions did not include the Ba-137m photon if Cs-137 was input
as a source term; the newer version asks you if you want it.  Extensive
documentation on both the use and validation of this program are available.
