MicroShield® is a comprehensive photon/gamma ray shielding and
dose assessment program that is widely used for designing shields, estimating
source strength from radiation measurements, minimizing exposure to people, and
teaching shielding principles.
MicroShield® is useful to health physicists, waste managers, design engineers,
and radiological engineers and only requires a basic knowledge of radiation and
shielding principles.
MicroShield® is fully interactive and utilizes extensive input error checking.
Integrated tools provide graphing of results, material and source file
creation, source inference with decay (dose-to-Ci calculations accounting for
decay and daughter buildup), projection of exposure rate versus time as a
result of decay, access to material and nuclide data, and decay heat
calculations.
MicroShield's® Features include:
-
Sixteen geometries that accommodate offset dose points and as many as ten
standard shields plus source self-shielding and cylinder cladding.
-
The geometry display for entry is re-scaled as dimensions are entered.
Dimensional data are accepted in meters, centimeters, feet, or inches. Display
can be rotated in 3-D for viewing and printing.
-
Library data (radionuclides, attenuation, buildup, and dose conversion) reflect
standard data from RSICC, ANS, and ICRP.
-
Provides the ability to access and use the Optional ICRP-38 Nuclide Library.
This library, which is significantly larger than the standard library, is
currently being distributed with RadDecay® 2.0. Microshield® will keep track of
which library is used an analysis or the creation of a source file.
-
Buildup and uncollided results are both automatically and simultaneously
calculated.
-
Provides the ability to design and save up to eight custom materials for any
case to add to the twelve built-in materials.
-
Sources may be created and saved and moved among cases, either as nuclides or
energies, and as concentrations or totals. Several photon grouping methods are
provided including custom (user defined).
-
Source decay can be calculated with daughter products generated.
-
As many as twenty-five energy groups (with an energy range of 15 keV to 10 MeV)
may be used; input may be concentration or totals.
-
Sensitivity of exposure rate to time, source dimension, shield thickness, or
distance can be investigated. Integration conversion verification can be
conducted with sensitivity to quadrature order.
-
Decay heat/energy can be calculated.
-
Improved flexibility for users to control input and output units, case file
saving, printing, and emailing, export of results including graphs to office
documents.
-
Provides the ability to define multiple (up to six) dose points for a case for
almost all geometries.
-
Provides the ability to operate on multiple cases simultaneously.
-
Improved handling of graphics including displayed and printed graphs as well as
the case model.
