  AlfaMC is a Monte Carlo simulation code for the transport of alpha particles.
The code is based on the Continuous Slowing Down Approximation and uses the
NIST/ASTAR stopping-power database. The code uses a powerful geometrical
package allowing the coding of complex geometries. A flexible histogramming
package is used which greatly easies the scoring of results. The code is
tailored for microdosimetric applications where speed is a key factor.
Comparison with the SRIM code is made for transmitted energy in thin layers and
range for air, mylar, aluminum and gold. The general agreement between the two
codes is good for beam energies between 1 and 12 MeV. The code is open-source
and released under the General Public Licence.
